New Year's Interval Training: 2 Sets by 2.5 K + 1 Set by 1 K

Jan. 1, 2020

Happy New Year! Where did you spend the moment the year changed? And how?
I spent it under the starry sky doing interval training! The streets were deserted and I kept them all to myself as I looked up at the beautiful Orion constellation every now and then.

Warm Up 3.16 K: 20:39.25
Rest: 1:00.05

Tokyo Marathon Test-Run 2019

Dec. 29, 2019.


I test-ran part of the Tokyo Marathon course with some runner friends of mine.
The weather was gorgerous, and the training was enjoyable.
We made many small stops along the way, sometimes to fuel ourselves, and other times to hydrate, and yet other times just take some photos taken.

We had lunch after running about 16 K.
Last year when me and my friends did the same,
we had lunch at the Ginza location of the Yoshinoya chain.
It was crowded, and we had to wait outside for quite a while.
It was freezing.
This year we had learned a lesson.
We went to the Kyobashi location, which is less crowded.
As we expected, we got to eat without waiting.

After lunch, we ran around the Imperial Palace.
The road around the Palace is perfect for running.
It consists of three sections: flat, uphill, and downhill.
The road that faces Tokyo Station is flat. The section from the north-eastern corner next to the meteorological agency onward up to the western side around the Chidorigafuchi Park is uphill.
Then from there on it's all down hill until the Sakuradamon Gate.

The road was crowded with holiday runners,
some jogging and others into a serious tempo run.
We were the slowest bunch of runners, being overtaken by one faster runner after another,
but we didn't care.

Around three o'clock we finished running it twice.
We called it a day, and headed back to our run base in Kanda.

After taking a warm long shower,
we went to a nearby restaurant
and congratulated each other on covering 30 K.

Midnight Barefoot Run

Dec. 23, 2019
7.7 K: 42:36.13

It's been a while since I ran last. I've been busy with corporate seminars, and had no choice but give priority to them. I was then going to do some quality training on the weekend, but a sudden seizure hit my stomach on early Sunday morning, and I had to stay in bed almost all day. It's quite unusual of me. I've experienced quite a few psychosomatic symptoms when I was under extreme pressure, but I was always aware that they were psychologically induced, and they would be gone soon once I was aware of it.  But this stomachache was totally unexpected, and wouldn't go away soon. It was definitely largely caused by a highly stressful work schedule, but I believed my mindbody would cope with it. It didn't. I suspect my sympathetic nervous system was too dominant, trying to cope with the busy schedule while the parasympathetic was subdued, which negatively affected my digestive system, thus resulting in the stomachache.


The pain's gone, and I felt strong enough for a jog, so I hit the road in bare feet. It felt good. In five days I'm scheduled to go for a long run in Central Tokyo with several friends of mine. It's going to be fun. I will run again on Friday night when two seven-hour seminars are over.

Yokohama Night Run

Dec. 28, 2019
13 K: 1:11:11

I ran around the Minato Mirai District.
I have an early start tomorrow, and am staying at a business hotel in Kannai.

Central Yokohama and the Bay area were both very quiet, good for a lonesome night run.

Barefoot Jog

Dec.17, 2019
8.64 K: 49:29.41


I jogged in bare feet tonight. It was cold, but there was little wind, so it was comfortable to run.


I ran the course above. It's rich in undulation, and most of it offers good road condition. Some parts have a rather deteriorated surface, and I had to slow down significantly. 

I've had run barefooted less often over the last couple of months, so my soles have softened a bit. I need to run without shoes more often to toughen them up, so that I will be strong enough by April to run the fastest barefoot marathon in the Kasumigaura Marathon 2020.

Park Workout: 100 M Sprint By 5 Sets & Others

Dec. 13, 2019
Today is my day off. It's one of the few opportunities for me to do substantial workout other than weekends. I hit the nearby park in bare feet to warm up by jogging 4 kilometers.

Warm Up 4 K: 21:36.98
Rest: 1:00.06


Once I reasonably got warmed up, I threw tires, something that I hadn't done since summer. I felt awesome. You can hit your back big time, but it's a total body workout that engages pretty much all major muscle groups. It's highly recommended if you have an open space like the one in the picture above, and an old tire that you don't give a damn about throwing.

70 Tire Throws: 10:25.83
Rest: 30.26


After 70 tire throws, I felt I'd done enough. But my legs were still kicking and alive, so I wanted to train them real hard. I chose to do 100-m sprint. I did it 5 sets. I timed each lap. When I saw my first time, which was 16.44, I wanted to run under 16.00, so I tried. I didn't run fast enough in the following lap, but successfully ran under the target in the following two runs. I was satisfied. 

<100-M Sprint>
1st: 16.44
Rest: 1:00.13
2nd: 16.16
Rest: 1:00.31
3rd: 15.81
Rest: 1:00.38
4th: 15.87
Rest: 1:00.16
5th: 16.24
Rest: 3:03.27


Warm Down 4 K: 24:12.34

I could have finished for the day after the sprints, but I didn't, because some fitness trainer said that you can increase the benefit of speed training if you jog after that. So I jogged 4 K before calling it a day.

I ran a total of 8.5 K in a little over one hour. The exercise included both fast runs and slow runs, as well as something that's of high intensity and explosive. I think it's a good mix, which usually helps me stay motivated while training.

Total: 1:06:10

Race Report: The Shonan International Marathon 2019

Dec. 1, 2019
42.195 K: 3:38:58 (Gross)/3:35:57 (Net)


On December 1, 2019 the Shonan International Marathon 2019 took place in Ohiso, Kanagawa Prefecture. I ran it in 999-yen marine shoes, and finished in 3:38:58 (Gross)/3:35:57 (Net). It's my first sub-3.40 marathon, smashing  my previous PR of 3:43:08 from the Tateyama Wakashio Marathon 2018 by 7 minutes and 11 seconds.

All in all, the event was enjoyable. The course is easy to run. Security is quite reliable. And aid is more than sufficient. Below I would like to write a brief summary of how I ran the race.

I arrived at JR Ninomiya Station at 6:08 a.m. Early arrival was strongly recommended by Toshi who ran a sub-3 marathon on this course some years ago. Thanks to his advice I was able to hop on a shuttle bus without waiting much. I was glad, because I was originally planning to walk from the station to the venue by walking for 35 minutes. This option was recommended by a female ultra-marathoner I talked with at Yokohama Marathon. She had run Shonan Marathon many times, and knowing how crowded shuttle buses always get, she would always walk to the venue. But I was able to save time and energy by taking the bus.

I waited for my runner friend Hashimoto-san in one of the tents put up for runners to get changed. He joined me about an hour after I arrived.

Runners are expected to gather in their respective corral an hour before the race. My corral is B, which is the one for those who aim at a sub-3.5 marathon. About half an hour before the start runners were guided into the start area from the waiting field. Once on the road where we directly faced the sea, there was nothing to block the sea breeze. I had a raincoat from a dollar shop on, so I was able to wait in comfort.



The gun went off at 9:00 a.m., and the race was under way!

 At 3.3 K I found my bilingual companion, so I handed the raincoat to her. I was originally planning to take it off and hand it to one of the volunteer workers, but the raincoat was a good one for the price, so I wanted to keep it. Though I had it on just to keep warm until the start, thanks to it I warmed up faster than usual.


I continued on at a comfortable pace, keeping my breathing in check. I was going to breathe in 4 beats, and breathe out 4 beats until I crossed halfway point. 

At the 10 K mark in Chigasaki, I saw the official time for the first time. I was 2 minutes ahead of schedule! I was surprised, because I thought I was going rather slowly. I slowed down a little, hoping to save energy for the latter half.

Shortly before the first turning point in Enoshima, I was expecting to meet my bilingual cheerleader, but to my disappointment I was not able to find her. 

Enoshima is one of the most popular cheering spots for sure, and there was a wall of cheerers on both sides of the street. I took off my marine shoes and ran in bare feet for a while. I felt great as the road condition was fairly good in the Enoshima area, and some of the spectators wildly reacted to my feat. Though I ran most of the course with shoes on in this race, this brief moment of barefoot running is one of the most memorable moments of that day.

At the 5th aid station at 19.2 K I grabbed 'uiroh' to fuel myself. It's a starchy snack made of rice, sugar, and a little bit of salt. I had three small packs. I felt a surge of energy. 

Between 20 and 30 K is the most crucial stage of the race. I was planning to increase the pace slightly, but not too much. A sudden increase in pace could take a toll on my legs, and I could need to pay a serious price later on. I seamlessly increase the pace, and whenever I felt a slight sign of spasm in legs, I slowed down to avoid any irreparable damage to them. 

When I finally reached the 30 K mark in one piece I felt a surge of relief. But there was still a long way to go. 


Shortly after I passed the Chigasaki Fishing Port a female runner talked me. She was interested in what I was wearing on my feet. She is a member of a running club, and two of the members are barefoot runners. She asked me if I was wearing socks, so I said to her that they were marine shoes with a meshy rubber sole. She and I talked for a while. Then we wish each other good luck, and parted. But from that point on, I kind of used her as a pacer, because she had such a beautiful running form and her pace was so metronomic. If I stuck with her, I would be able to run a pretty good race, I thought. And I proved right later on.

After 30 K there was a series of upward inclines including the Shonan Ohashi Bridge, but I like uphills. I spent so many hours hitting them in training. I attached them strongly by swinging my arms more dynamically than when running flat parts. 

When I finally saw the Ohiso Prince Hotel, I said to myself, "Now the real game begins!" Before the race I was told by Toshi that it's quite demotivating to see the finish area on your right, and yet there's still almost 5 more kilometers to run. But I was up for the challenge. I love the hardest part. All my previous training effort was for this particular moment, I said to myself. I looked down at the shoes other runners had on, and whenever I saw NIKE's latest model, I overtook him. When I say another, I overtook him also. I said to them in my mind, "Come on, brother, don't you have those state-of-the-art carbon-plated shoes on to run fast? How can you let a caveman with marine shoes with little cushioning run faster than you?" I'm kidding. That's how I wanted to run. The truth of the matter is that I was so preoccupied with my own pain I couldn't think about anything but taking each step forward. 

The 3 kilometers after the hotel was in sight on the right was the longest 3 kilometers that I had ever run. But when I finally turned around the second turning point and crossed the 40 K mark right after that, I could feel a surge of energy welling up inside me. I closed my eyes and ran. I wasn't looking at anything any more. I was following my mental vision. How on earth can you do it, you may ask. But I just do it. In my mind I visualized an imaginary K. I ran 100 meters in my mind, then the remaining distance is 2.1 K. I ran yet another 100 meters. So now the remaining distance is just 2 K. This way, I counted down the remaining distance in my mind. What I was doing, though, was tricking my mind so that when I thought I still had 500 meters to run, the actual remaining distance is only 300 meters, because it's motivating. It's far more motivating to find out that you need to run less that you thought you had to run, than when you need to run more than you thought you had to run.


Anyway, when I took the turn leff off the Seisho Bybass into a narrow driveway into the hotel, I knew it's almost over. A smile crept across my face, I could feel. There was a sharp left turn from a parking lot into yet another drive way that led to the amusement park adjacent to the hotel. The finish line is located in this park area. The driveway was a steep uphill, but it was short, and lined with a whole bunch of cheering spectators. 

Once I reached the top of the hill, the finish arch was in sight! It looked 200 meters away. I heard a deep voice of a female runners behind me. He seemed ready to kick. I didn't want be overtaken. I kicked first, suddenly into track mode like Eliud Kipchoge in the last 500 meters of the Ineos 1:59 Challenge in Vienna, Austria. The official clock was insight. I couldn't believe my eyes. It was clocking 3:38:55, 56, and 57...Goodness me! It's gonna be my first sub-3:40 marathon. And suppose it's gross time, my net time will be even better.

And sure enough, after I crossed the finish line, I discovered that my net was 3:35.57. I smashed my previous PR by 7 minutes and 11 seconds. In marine shoes, with no runner's watch on, and running part of the course in bare feet! 


After the race I had the most delicious beer with my runner friends Hashimoto san and Yuko.

1 K @ 4:30 Sandwiched with a 20-Minute Jog

Nov. 28, 2019

Warm up 3.5 K: 20:20.56
Rest: 30.28
1 K Fast Run: 3:59.41
Warm down 3.5 K: 20:52.20
Total 8 K: 45:42.45

With three days until the race, this is the last speed training. I jogged for 20 minutes before a fast K @ 4:30 pace. I ran carefully not to further damage the left calf that had lingering tension. I clocked 3:59.41. I was surprised, because I didn't feel like I was going fast. I even slowed down a little toward the end. And yet I finished under 4 minutes. I guess my cardio has gotten a lot stronger from running the Yotsukaido Gas Light 10 K Road Race.             


I was originally planning to do two fast runs, but after the first run, I felt a slight discomfort in the left calf, so I switched to jogging. As I jogged carefully so that stress on the calf would be minimum.

After taking a shower, I fueled myself  amply, and massaged both calves thoroughly. Hopefully, they will have been pain-free by tomorrow morning.

Tomorrow if I can get up early enough, I may go for a walk for 20 minutes and do some park work out. If I don't, I'll just run for 30 minutes or so, and the last stage of tapering before the race will be over.

One-Hour Jog in the Rain

Nov. 27, 2019
12.03 K: 1:02:00

Five more days to go before the Shonan Kokusai Marathon 2019. I've been roughly following the tapering method recommended by former ultra-marathon world best record holder Mr. Takahiro Sunada, and what he recommends five days before the race is one-hour jog, so that's what I did. 

It started raining just before I left home. I thought it perfect for acclimating myself for potential bad weather on the race day.

I put on a pair of 100-yen flip-flops turned into semi-handmade huaraches. 


I was planning to run at  6:30/K, but before I knew I was going a lot faster. When I almost finished running the 10.5 K loop below, it was still 8 minutes till one hour, so I ran an extra couple of kilometers to run just a little over one hour.


I felt a slight tension in the left calf. I gave it a thorough massage after taking a shower. I might skip running tomorrow, and do core training instead, just to rest my legs a little.

One-Hour Recovery Run

Nov. 25, 2019
Warm up 750 M: 4:23.56
2.5 K: 14:34.37
2.5 K: 14:13.60
2.5 K: 14:35.83
2.5 K: 14:25.33
Warm down 750 M: 4:26.82
11.5 K: 1:06:39

Six days to go before the race. I cruised around a 2.5 K loop near my home four times to check my running form as well as to relax the tension in the leg muscles resulting from the tempo run on the previous day. 

The course in the next race is pretty much flat. It's a shuttle course with little change in landscape, though it's all along the coast line and the view of the Pacific Ocean can be enjoyed from time to time. Water & food stations are frequently available and famous local sweets are offered at some of them, though I won't be bothered to enjoy many of them.  

I watched a video showing the course the other day, and have a pretty clear picture of how I want to run the race. I will probably go easy until the first turning point in Enoshima. It will be only after halfway that I will pick up the pace just a little bit. Even then, though, the pace increase will be very slight. I will be very patient until after 31.5 K where the 10th water station is supposed to be. 

I will then shift the gear and increase cadence. Once the finish area is visible on the right on my way to the second turning point in Ninomiya, I will increase the pace further. And then after the turning point, I will take off my aqua shoes and put on a spurt for the last two kilometers, hopefully overtaking those clad in NIKE's Next%.

3 Sets by 6 K

Nov. 24, 2019
Warm up 880 M: 4:57.83
Rest: 30.34
6 K: 30:06.54
Rest: 3:45.37
6 K: 26:25.71
Rest: 1:00.38
6 K: 33:31.50
Warm down 1.38 K: 11:03.44
Total 20.26 K: 1:51:21

After sleeping 8 hours, I woke up refreshed, ready to hit the road.

With one week remaining, this weekend is the last chance to do quality training.

I haven't been able to do the training I wanted to do mainly due to lingering pain in my left calf and fatigue resulting from insanely busy schedule. But the worst is over and the pain is gone. So I was up for a challenge.

I was going to run 6 K three times at increasingly faster paces, first around sub-4 marathon pace, next at sub-3.5, and finally even faster.

But I was much faster than the respective targets in the first two sets, but significantly slower in the last. But that's OK.

I ran in the aqua shoes above. I'm most likely to run the Shonan Kokosai Marathon 2019 wearing the same shoes. They are super light, don't soak water in the rain, give my feet the minimum protection that they need. My PR was achieved when I ran the Tateyama Wakashio Marathon 2018 in the same type of shoes of a different design. They are proven the best!

Yokohama 90-Minute Night Run

Nov. 19, 2019
16 K: 1:32:20

Yokohama was so beautiful at night, and it was perfect for a night run. The view of the Minatomirai district across the bay from the Ohsanbashi Pier was breath-takingly beautiful. It's perfect for a night walk with someone you love, or you are in love with. It takes your breath away, and his or hers as well for sure.

Yotsukaido Gas Light 10 K Road Race: Race Report

Nov. 17, 2019

On Nov. 17, 2019 the Yotsukaido Gas Light 10 K Road Race took place in Yotsukaido, Chiba. I ran it in bare feet, and finished at 44:18. The time is average, but the context of the race was unique in that two weeks later I was expecting a full marathon. I had never had a full marathon so close from the race. It caused me a lot of inner conflicts that I wasn't aware of. Here is what happened and how I coped with it.

First, I was going to go for a new PR this year. Last year I ran a 41:02. I was confident I could do better if I trained well. I did some intensive hill intervals to prepare for the race. A week before the race, I test-ran the course just for a mental rehearsal. While running, with a couple of kilometers remaining, I felt a nasty pain in my left calf. I walked awhile, and then ran again, but the pain wouldn't go away. I managed to run the remaining distance, but while riding my scooter back home, I was worried that the pain might not go away until the race day.

From the following day on, I stopped running, while doing some body weight core training to keep my cardio active and stay fit. 

The morning of the race, the pain was still there. I was ready to cancel it, but went to the venue anyway,  because two friends from my high school days were running, and I wanted to cheer them on even if I didn't run.

Once I got to the venue, saw my friends, and soaked up the festive atmosphere, though, I just couldn't control my urge to hit the road. So I decided to run. But since the pain was still lingering, my purpose of running was no longer time, but just to check my form and to run without causing much strain to the pained part in the calf.

Last year I started from the front corral for fast runners. This year I settled for a much slower corral to just to keep talking to with my friends from high school until the moment of the start. Running a fast race was no longer on my mind.

The gun went off, and runners flew through the first downhill. I ran with Akira, who ran a sub-3 marathon in his late twenties. I was surprised that once the race began, the pain in the left calf that had previously worried me so much seemed to fade away. I cruised along the street like a rolling stone. 

The pain in the left calf continued to be no problem for the rest of the first half, and I continued to increase pace to overtake one runner after another who was now paying the price of the fast pace in the first few kilometers.

Between 5.5 and 6 K or so, there is a long downhill that received a lot of sun. I hammered down it for time gain. I was surprised at what I was doing. I was trying to run fast! 

Once I got to the bottom of the downhill, I turned left, and there was a long stretch that lasted almost two kilometers. I slowed down slight at first because the road was going up a little. I tried to let my heart rates come down to recover from the latest surge. 

I ran carefully not to injure my left calf, and it worked. When I made the last left turn into the final stretch to the finish, I was almost pain-free, though slight tension was building in both of my calves, which seemed inevitable. 

The last stretch was one long downhill, one steep uphill, another long down hill, and another long uphill, and then a flat road to the finish. Considering the energy that I would need to attach the forthcoming two uphills, I didn't bang down the first downhill as aggressively as I had done the previous one near the 6 K mark. Then came the first of the two uphills. I swerved to the right to run on the yellow paint in the center of the road. The surface was smoother there. I took shorter strides for running economy, but by then building fatigue was making my breathing difficult, so I had to significantly compromise on speed when going down the second downhill not only because of the increasingly difficult breathing but also poorly-maintained road surface. 

The poor road condition remained while going up the last uphill and also on the last stretch leading to the finish line as well. I was hoping to surge there, but with the difficult breathing I had to settle for a rather average pace. I crossed the finish line with both my arms thrown into the air with joy!

My time wouldn't be so good, considering the slow pace in the first few kilometers. Plus, it wasn't the main purpose today after all. 

In no time Akira returned. And several minutes later Sakata, the other friend from my high school days came back. We exchanged high fives, and walked back to the gym to get changed. 

On our way there we went through a tent where finishers' certificates were given. I received mine. It said 44:18. I smiled, remembering the days when I first started running. Back then no matter how hard I ran, running under 45 minutes always seemed rather difficult to achieve. I pat myself on the shoulder for my personal growth over the years. Through commitment and hard work even an aging man can train to run faster.


After crossing the finish line some runners came to me to say hi and ask how my feet were. There was just one other barefoot runner in the race. I talked to him when I overtook him. He came to me because he wanted to get a photo taken with me. I was honored.

Another person who wanted to chat with me was a young boy who looked like a high school student. He excited told me that he was following me all throughout the race. I shook hands with him, saying, "You are a young man. Young men can do anything. You should run barefoot someday." He didn't say yes, but excitedly smiled as he left.


After the race Akira invited me and Sakata to his home near the venue. We wined and dined for three hours, updating each other and discussing some exciting things around our lives. I am glad I have such good friends to run and talk with.

To be continued...

Yotsukaido Gas Light 10 K Road Race Test Run

Nov. 11, 2019

Six days until Yotsukaido Gas Light 10 K Road Race 2019. Just wanting to get the feel for the course and mentally rehearse the race, I hopped on my scooter to the venue after dinner, and test-ran the entire course.

I parked the scooter in the park near the start line, and took off my windbreaker pants and down-jacket to get ready.

There was some traffic near the start area, but after running for a couple of kilometers into the residential district, it suddenly became quiet, and I was alone on the road.

In the first 2 kilometers there are two steep downhills and uphills. With my legs still fresh I'm hoping to run through this zone under 8:10, though there will be no knowing how fast I'll be going because I won't wear my Ironman running watch. It's too distracting to run with the watch on.

The last few hundred meters of the first 2 K are going down slightly. I want to pick up pace there. Then the course turns left into a long stretch. The road surface is very smooth there. It's perfect for barefoot run. But the last half of this zone is a slight upward incline. This is where running efficiency is most important. If I run too economically, increasing cadence, but shortening strides too much, I can sacrifice time. If I use my quads and calves too much here, my heart rates will go too high, and I can struggle in the second half. I will probably life my knees nice and well so that I can smoothly turn the landing motion into forward movement by using tendon more than muscle.

In the last K of the first half and the first K of the second half, the road condition suddenly gets worse. It gets rough, and the paint of the line is poorly-maintained. So it will be rather uncomfortable 2 kilometers.  But this is also the area where I get to see runners who are still on their way to the turning point. I usually get some real good cheering yells from my runner friends around here. I'm hoping they will lift my spirit.   

Once the poorly-maintained zone is over, the next 3 kilometers are downhill. This is the only opportunity for me to mark any significant gain, because the last 2 kilometers are ups and downs, and the legs are expected to be suffering from building lactic acid. With roaring cheers from both sides of the road I will give it everything I have to maintain the pace that leads me to the target.


During the test run, what was originally only a slight discomfort in my left calf became a pain, which I had to deal with by slowing down. It must be cure before any serious running training. So tomorrow and the day after tomorrow, I will avoid running and do some core training instead. But I will make it intense, and do it many sets so that I can keep my cardio.

6 K Tempo Run @ 4:05/K

Nov. 9, 2019
6 K: 26:09.66 (average 4:21.5/K)

With 8 days remaining until the Yotsukaido Gas Light 10 K Road Race I did a 6 K tempo run. The target was 4:05/K. I was originally planning to hit the road immediately after dinner, but I was so sleepy and exhausted from an insanely busy work schedule and a resultant chronic lack of sleep. So I took a short nap for a couple of hours, and finally got out past midnight.

It wasn't so cold for early November, but definitely cold for a shorts-& short-sleeved-shirt-clad run. But nonetheless I got out in shorts and no-sleeved running shirt, because quick rise of body temperature was expected because of the nature the training tonight.


I chose to run the loop above, because it's rich in undulation, similar to the race course. 

As soon as I started off,  I quickly realized that the two-hour nap wasn't enough to revitalize my mindbody. My legs were heavy and breathing wasn't easy. I immediately wanted to call it off. But I carried on. A few minutes into the run, I felt a sharp pain in the right lung. I suspected that the diaphragm was cramped. I felt suffocated. I wanted to quit. But I chose to accept my limitation and settle for less rather than totally quitting and gaining nothing. 

I did my best to shake ff the pain by changing the breathing tempo, or breathing out everything and get more of fresh air, and so on. But nothing really worked until I reached the goal.

The time was 26:09.66. Far from the target. But I came through the pain and completed the session. I am satisfied. 

I'm afraid I pushed too much. There is a slight pain in both of my calves. It's not good.  I'm going to rest tomorrow. The Yokohama Marathon 2019 takes place tomorrow and three of my runner friends are running. I'm going to there to cheer them on.  It's going to be a fun and enjoyable Sunday with no hard training on my side.  It's my friends who do all the running.  All I do is just cheering.

10 K Barefoot Run

Nov. 8, 2019
10.5 K: 57:27.00

I ran in bare feet for the first time in a long time. It felt good. I took care of a blister in my right sole, and that took awhile to heal. The treated area still looks slightly awkward, but that doesn't distract me from running comfortably.


Thanks to the interval training on the previous night, my legs felt light, and breathing was a lot easier than usual.


Tomorrow at night I will do a 6 K tempo run @ 4:05/K. The target is running it under 24:30. I'm thrilled to give it a try.

I made a promise with myself, and kept it. I did one set more than last time. I also threw in extra two sets at the end of the session tonight. I finished under the target of 4:05/K in five of the six sets.  I'm satisfied. My last speed training before the race is either 6 sets by 1 K intervals or 6 K tempo run. I will decide which to do depending on my mood when the day comes.

Hill Intervals: 3 Sets by 1 K @ 4:05

Nov. 4, 2019
Warm up 2 K: 11:51.54
<Hill Intervals>
1st K: 4:05
Rest: 1:00.00
2nd K: 4:03
Rest: 1:00.00
3rd K: 4:02
Warm Down 3 K: 16:29.31
Total 8 K: 44:11.68

I did hill intervals. I ran 18.6 K on the previous night at a very comfortable pace, so my body was reasonably loosed up. So I warmed up shorter, and got right into intervals after warming up by running just 2 K. 


I finished under the target in all three. But a second after I set off for the 4th set, I felt I was out of gas, so I switched to a jog and slowly headed back home from there.


I must be able to repeat this pace 10 times to meet my goal of running 10 K under 41 minutes. The real race course is a lot less hilly, so I should be able to run faster if the road is flatter. But I want to be able to repeat the K at this pace at least three more time to do a total of 6 sets. We'll see. The first time I tried, I only did twice. Tonight I did it 3 sets. Hopefully, next time I can do at least one set more than 3. Then this weekend, I want to try a 6 K tempo run @ 4:05/K. It's my weekend fitness goal. 

Tokyo Midnight LSD

Nov. 3, 2019
18.6 K: 2:45:00


I partied with an old friend of mine. We wined and dined, and I missed the last train. I jogged across Central Tokyo and reached the Keisei Ueno station at 4:15 am. I dropped by a buck-wheat noodles restaurant open 24 hours, and killed time. I caught the first train at 5:03 am. I fell asleep immediately. Next time I woke up, I had missed my stop. I turned around and finally got back home around 6:30 am. 

No sooner had I got home than I hit the bed. I slept like a log. Next time I woke up, it was 5:00 pm. I slept 10 hours straight to wake up a new man. I had oyster ramen for breakfast/dinner. I feel like I could run another 20 K. But I won't. Because tonight I am going do intervals, where I run shorter distances, but fast.

Hill Intervals: 2 Sets by 1 K @ 4:05

Oct. 31, 2019
Warm Up 3 K: 17:41.21
Rest: 1:00.07
<Intervals: Target 4:05/K>
1st K: 3:50.64
Rest: 1:00.11

Warm Down 3 K + Park Workout : 22:47.62
Total 8 K: 51:06.16


I did hill interval training this morning.
I don't usually do it in the morning. I'm nocturnal.
I tend to feel more focused at night.
Plus, traffic is less at night than in the morning.
So it's safter to run at night as well.
But last night I had a slight headache
probably from chronic shortage of sleep.
So I decided to take a short nap,
hoping that I'd be strong enough to run
after an hour of lying in bed.

When I opened my eyes again, it was 7 hours later,
and I still felt sleepy. So I slept two more hours
and got up at 10:00 am. I slept 9 and a half hours.
Though I missed my midnight training,
I felt reasonably recovered, ready to hit the road.

I changed into my running gear and headed for the hilly shuttle course
where I was planning to run last night.

My body felt heavy, and I was worried that I might not meet the challenge.
The challenge is running 1 K @ 4:05, and repeat it 5 more times with a minute's rest.

I calibrated the alignment of my joints as I ran along, trying to find the most efficient form that generated maximum power with minimum effort. I reached the venue before I was satisfied. But there was no waiting.

After taking a short break, I lifted off for the first set, hammering down the road like a thunder. I knew I was going a lot faster than my usual training pace. This time the goal is different. I usually train for full marathon. This morning I trained for 10 K. I must build greater lactic acid tolerance. To raise the threshold I must run faster, and sustain the effort at  least for 41 minutes.

The first half of the course is downhill. Iliacus muscles aren't that required. But quads are tremendously activated. I could feel them cry as I banged down the hill.

Then the second half is uphill. It's steep and long. This time iliacus muscles are  tremendously activated. I must raise my knees nice and quick and turn each kick into forward momentum. My strides got shorter to improve running economy. But if I do it too much, I sacrifice speed. I ran through a fine line between maintaining speed and optimizing running economy.

The first lap was 3:50.64. Well under the target. But I was out of breath, already on the verge of getting burned out.

I rested for a minute. While resting, I wondered whether I should go for another set or not. The first set was so fast. I felt like I'd had enough for the day. But I decided to give it another try, no matter how pathetic the set might become.

As I set off for the second run, I immediately knew that it wouldn't be a good set. My legs were heavy, and breathing was difficult. But I pressed on nonetheless.

The second set, which is going the route of the first set in the reverse direction, begins with a steep downhill. It sounds easy, but puts a tremendous amount of stress on the quads.

Once you hit the bottom of the downhill, a short flat stretch continues. This is where I readjust the alignment of my body, trying to find the best form to attack the forthcoming uphill. Then when I reach the bottom of the uphill, I change my gear, take a little shorter strides and quicker steps, and use my arm swing more to create a driving force up the hill.

The lap was 3:46.25. To my surprise the time was better than the first. I was satisfied. But there wasn't a drop of gas left in my tank. I feebly walked to and fro to calm down my breath. A minute later I weakly headed back home.

On the way back I stopped by a small park to get some water and do some bicep workout. Later on when I passed yet another park, much larger, I did hand-clap push-ups just because I was in a mood for it.

When I got home, took a warm quick shower, and had a healthy breakfast consisting of grilled fish, boiled pork guts, boiled veggies, yogurt, and fresh fruits, I felt like a new man who was so full of energy that he could do anything.
