Swing Push-Ups and 6 K Barefoot Run



I did some park workout followed by a 6 K barefoot run. It's a recent favorite combo of mine. Today I did swing push-ups. (To see what a swing push-up is click this link: https://www.youtube.com/watch?v=GmAgFUi_PHY)You put one hand on the seat of one swing and the other hand on the seat of another right next to it. As you push up, you bring the two seats inward until they touch each other. You can create peak contraction of your chest muscle this way. I tried an approach called "21" favored by Arnold Schwarzenegger. In this approach you start from the bottom position, push up halfway, instead of pushing all the way up. As you do this, of course, you bring the swing seats together inward. You creep down as you let the seats go apart from each other, and repeat. You do it seven reps. The next seven reps begin from the halfway position and end with the top position. Again the movement of bringing the seats inward is involved as you do it. The last seven reps involve full range motion. You begin from the bottom and push all the way up to the top as you squeeze the seats inward. I did this two sets before a 6 K run, and did another after it.

The 6 K that followed the park workout was refreshing. I love running in the morning. My body's will power batteries are fully charged. The air is fresh. And I'm full of legs. I am trying different running forms as I go along. It was shocking that I had a cramp in my thighs when I ran the Sakura Marathon this past March. I hadn't had any muscle problem whatsoever in major running races over the last couple of years. I was confident that I was strong enough to avoid problems of that sort. But the reality is that I was miserably brought to a halt because of a cramp in such a crucial muscle as the front thigh. The problem can be attributed to a number of reasons. It could be heat. It could be dehydration. It could be inefficiency in running form. It could be a combination of all or many of these. Anyhow, I want to fix something I can immediately get my hands on, that is, my running form. I can improve it when I run without shoes. This is because barefoot run is far more uncomfortable than shoe-clad run, and therefore you inevitably choose a running form that is least painful. And that is the form I want. Only that allows me to run a full marathon distance with least pain. I will continue this short test run. And when I feel comfortable enough with my running form, I want to increase mileage.

High Intensity Cardio Followed by a 6 K Barefoot Run


I did 7 sets of one-minute high intensity cardio using an old tire. The purpose of this training is to strength my cardio-vascular capacity.

After that I ran 6 K in bare feet. It was the third barefoot run after the Sakura Marathon. The time was the best out of three tonight: 31:07.65.

Experts say that it's a good idea to do long slow cardio such as running after using up much of the glycogen in your muscles, because your body has no choice but tap into your fat reserve for energy source to sustain the slow cardio activity. I'm not sure if it was the case tonight, but one thing I noticed was that as soon as I started running I was already sufficiently warmed up, so it was easy for me to pick up the pace. I may want to stick to this combination for a while: high intensity cardio first, and long slow cardio after that.

6 K Barefoot Run


I ran 6 K this morning in bare feet. The pace was a little faster than two days ago. I didn't mean to run faster. But when I got home and saw my watch, I was almost three minutes faster. I guest my will power tank was full after a good night's sleep, and I was physically fully recharged as well. I enjoyed overtaking cars caught in a traffic jam. It's a laughable irony that runners can be faster than cars during rush hours. There is some soreness left in my right foot from the Sakura Marathon, so I won't go for a longer and faster run any time soon. I will continue to run a short distance like this, but will do so frequently to stay in shape. I'm invited to a relay race held in the US Air Base in Yokota in May. So I will do some speed-focused training a few weeks prior to it. My mind is already set to run the race without shoes. I will continue to improve the durability of my sole until then.

First Run After the Sakura Marathon: 6 K in Bare Feet


I ran a 6 K shuttle course in my neighborhood after coming home from work. It was the first running training after the Sakura Marathon. I was a bit sore from high intensity cardio that I did on Sunday, and I wanted to loosen up my body with some slow cardio. And that's where a comfortable jog comes it. I ran barefoot as my sole had gotten quite tough after completing a full marathon in minimalist aqua shoes. It was largely painless throughout the entire 6 K except for a very few cases where I accidentally stepped on a tiny, edgy pebble. It was tremendously refreshing to run without shoes. I like feeling the cold of the road surface on my sole. I also like feeling the air directly on my feet. To me shoes are extra weights no matter how light they may be. Also, shoes get worn out as you wear them for long. But your sole, which is made of a genuinely organic material, maintains itself automatically after each use. You don't need to fix the heel with Shoe Goo, or anything like that. No shoe lace is needed either.  

As I had a very comfortable, and almost pain-free run for 6 K tonight, I became more and more interested in running more races entirely barefooted.  My next big race is almost 5 months away, and I have plenty of time to think about what kind of goal I want to set for the next race season. I can go for better times. I can go for a longer distance. But I can also run for a new kind of athletic challenge. Running without relying on modern athletic technology seems to me a good enough challenge. Because there are so many runners faster than me, but I don't see many who run without shoes.

Race Report: Sakura Asahi Kenko Marathon 2018

On March 25, Sunday Sakura Asahi Kenko Marathon 2018 took place in Sakura City, Chiba. I ran the race and finished in 4:03:21 gross (4:02:22 net). The time is the worst of the four races run in the last two years, and the race was by far the most painful one. But nonetheless it is one of the most memorable days for me, thanks to companionship of my runner friend, Hashimoto-san, as well as friendship of many who came over to cheer me: Ui-san, Yukie-chan, Kiuchi, Nemo-cchan, and the Nakajima Sisters. Although the time is far from what I wanted, I feel proud that I ran the race in aqua shoes with no cushioning, and that I took them off with 1.5 K remaining, and that I crossed the finish line in bare feet as a tribute to my all time fitness hero late Abebe Bikila of Ethiopia who won the gold medal in men's marathon in the 1960 Olympics in Rome without wearing shoes. Running with less reliance on modern athletic technology than the previous season was a big goal for me and I achieved that goal.

Below is how I ran the race. I hope those who consider joining the race next year can benefit by reading it as it describes some characteristics of the course and how I approached it to run it well.


(Two hours before the race)
The race was officially under way at 9:30 a.m. It doesn't take much time to reach the official start line from your corral as there aren't as many participants as major races such as the Tokyo Marathon or the Ohme 30 K Road Race. I always start my watch at the official start time, but it was only a minute or so after it when I crossed the start line. 

Once out of the stadium, the course begins a long steep descent into a road that eventually leads to Keisei Sakura Station. You go over a hill that stretches over almost two kilometers. My strategy here was to use it for warming up myself. It's a long, long race. You don't want to hammer it up and waste energy here. I enjoyed a comfortable climb at an easy pace. An episode to illustrate how relaxed I was is that I saw a guy running in a pair of "warachi" flip-flops and had a friendly chit-chat with him. 
(Shortly after the gun went off)

Soon I crossed the 10 K mark, and took a quick look at my watch, which said 57:00. I thought not bad. I wanted to run the fastest in the last 7 K, so I decided to keep the same pace until I reached the 30 K mark. I had water at almost every water station. It was important, because it was hot. Daytime highs were expected to reach 20 degrees Celsius. Also, I hadn't had much water before the race to control my urge to pee during the race. In the previous full marathon in January in Tateyama I took total 3 pee breaks during the race, and I had so much trouble catching up to the 3:45 pacers after taking the third one. I didn't want to make the same mistake. 


(Near the 14 K mark)

Near the 14 K mark I saw my bilingual companion. I asked her to prepare half a piece of sweet sponge cake when I pass the 18 K mark which was not so far from where she was. Soon after I left her behind came one of the biggest challenges the course had to offer--a long steep hill leading to the Kusabueno Oka Hill. I took shorter strides and slowed down so as not to increase my heart rates. A number of runners overtook me, but I didn't care. They are inexperienced runners who knew nothing about its consequence. At the top of the hill many were gasping for air. I ran past some of them like I picked apples from the tree. 

Near the 18 K mark I received the sponge cake from my bilingual companion and also had some water from her water bottle. Up to that point I had water as well as sports drink at every water station, but I found myself slightly dehydrated. At the halfway point my watch said 1:50:00. I was running faster than I had originally planned to. But I didn't feel like I was pushing, so I went with the flow. At the 26 K mark the course turned into the cycling road. I was feeling hotter and hotter with each step. I felt my heart beat harder though I was running any faster. I felt the need to slow down to save energy for the final phase of the race. No sooner had I slowed down a bit than I heard approaching foot steps from behind, and in less than a minute I found myself being overtaken by a large group of runners led by 3:45 pacers. Though I wasn't aware I was running in front of the pacers, I clearly realized at that moment that my pace was getting slower than theirs, and if I wanted to finish under 3:39:59, I had no choice but stick to them. So although it was getting tougher and tougher for me to keep the same pace as in the first half of the race, I decided to hang on to them. Soon I came to the largest cheering spot at the 28.5 K mark near the windmill, where I was cheered by local friends mine from my junior high school days. I looked hard for them and found them at last, but I made a fatal mistake at the same time. I missed the water station that was on the opposite side from the one my friends were on. The next station was between the 33 and 34 K mark. I prayed for god that I would last till there. 

(At the 28.5 mark by the windmill)

Unfortunately, I didn't last till there. With each step my dehydration became more and more apparent. And finally near the 30 K mark I got a first spasm in my left hamstring. I had to stop. My heart sank. I stopped there for about twenty seconds and did some stretching. I knew then that I would never renew my PR today. But I never wanted to quit just for that reason. I never want to be a quitter. I slowly started to run again, but was stopped from time to time by a series of painful cramps. I wanted to cry from misery. When I finally saw the next water station near the 34 K mark, although it was visible, it seemed like an unreachable paradise across the ocean. It seemed like a phantom that I could never touch. It looked so far far away... When I finally reached there, I came to a complete halt and gulped two cups in a row. I grabbed a cup of sports drink too and had it in one gulp. Soon my stomach felt like a balloon full of water inside. I started running again, but I felt heavy. I no longer felt like a runner. I felt like a patient. But I kept on dragging my legs forward. 


 (At the 35 K mark)

At the 35 K mark the bilingual companion was waiting. She knew something was wrong. I saw her face. She looked sad. I felt so bad that my running wasn't impressive. I put so much effort into it, and she believed that I'd run a good race, and now this. I briefly told her what happened, but that I would never quit. I left her behind and moved on. 7 K is a breeze when you are full of legs. But once they start malfunctioning, it feels like forever. When you are running well, cheerers encouraging comments bring out the best from you. But when you are not, they don't necessarily. In fact, there is nothing you can do to live up to their expectations, that you feel so miserable that you almost want to kill those well-intended people for a moment. You can be that desperate. 

Shortly past the 39 K mark I was finally overtaken by the 4:00 pacers. I made my utmost effort to stick with them, but I could only do so for a little less than one kilometers. And when I finally crossed the 40 K mark, my legs were so sore that I almost considered dropping that idea all together of taking off my shoes for that glorious barefoot finish as a tribute to my all time athletic hero, late Abebe Bikila. But the main street was in sight, where the road condition improved and there were more cheerers, I made up my mind to stick with my original plan. I stopped and took off my aqua shoes, and rolled them up and grabbed them in my hands. It was at that moment a switch was turned on and I felt like a reserve tank was untapped. I forced down the road like a new man. Taking a right turn into the street leading to the stadium, the sound of cheering drums became louder with each step. Suddenly I heard a female voice saying, "Gakuji senpai!" Not many people call me that. I turned to the right. And there was my team mate from my high school tennis team together with her older sister who is a hard-core sub-3 marathoner. I thanked them for their cheering, and headed for the final hill-climb which is the highlight of this course.   

(800 meters to the finish line)

With 500 meters remaining the road splits into two, one going right and down and the other going left and up. The course, of course, goes left and up. Some cheerers noticed I was going barefoot, and threw some words of admiration at me. They gave me some extra power to forcefully ascend the heart-break hill. The bilingual companion was halfway up the hill on the right side of the road, ready for memorial photo-shooting. The moment I saw her eye-catching green down vest, I threw my right arm up in the air with a clenched fist. I took steady quick steps up the hill with my back upright. I wanted to finish strongly. 

(400 meters to the finish line)

When I finally reached the top of the hill and the course became flat again, the large yellow arch above the finish line was in sight 300 meters ahead of me. I surged for the last time, swinging my arms like a track athlete. The track of the stadium was comfortable on my soles. All the effort was finally being rewarded. The time was far from what I wanted. But I was about to cross the line in bare feet. I couldn't run as fast as so many runners who had already finished the race before me, like Abebe Bikila beat all the shoe-clad rivals in the 1960 Olympics in Rome, but I beat the demon of the sport who whispered into my ear countless times that I could quit and that I should keep shoes on. Half a minute later I became an official finisher of Sakura Asahi Kenko Marathon 2018 with the gross time of 4:03:21.

As soon as I finished the race, I gave my runner chip to one of the volunteer people, and grabbed a few cups of water offered by another young volunteer worker.  I lay down on the grass inside the track after the drinks, and a moment later fell asleep. It was almost half an hour later that I was waken up by an aid worker who worried that I might be dead and asked, "Are you OK?" I said, "Yeah, I'm OK. I was just sleeping." I was that exhausted.

I went to Iwana Sports Park today to test-run the first 17 K of the course I'm running this weekend in Sakura Asahi Kenko Marathon 2018. I mixed in surges of varied lengths at regular intervals to build my fatigue resistance. 

I am so glad I ran the course today, because I was able to check the road condition. In much of the course the surface was very rough. The sole of one of my aqua shoes, which had resisted the shock and friction throughout the entire 42.195 K at the Tateyama Wakashio Marathon this past January, got a hole! I also got two blisters in my right sole. That didn't happen when I did similar training last week for a much longer distance in Tesla's Baretrek. I have an extra pair of aqua shoes, and I can use them at the race this coming week. I don't know if the same can happen there as well. I hope it won't. And I have reason to believe it won't. First, I won't run as fast in the race as I did in the training. And when I ran at my race pace in Tateyama, the sole didn't get damaged. Also, the sole probably was slready pretty worn out as a result of past frequent use. But the new pair is, as you see, brand-new and least worn-out. So I may run in Baretrek if the blisters don't heal, which is still a pretty good option for a minimalist (though a bit too protective for a man who respects Abebe Bikila), but I will mostly likely run in aqua shoes if the blisters present no problem.

Cruise Ks: 8 X 1K @ Half-Marathon Pace (4:30/K) with 60 Seconds Recovery Between Reps

I did cruise Ks. It's a close cousin of the tempo run. It's essentially a sustained effort broken into smaller chunks with a short recovery period between repetitions. It's a great way to get in some lactate threshold work without totally destroying yourself, whereby you can develop your ability to maintain decent performance under the influence of building lactic acid in your leg muscles. It's a decisive element in the final phase of a long-distance race.

Tonight I did 8 reps of 1K at my half-marathon pace of 4:30/K with 60 seconds recovery between reps.

The detail of the training tonight is shown below:
1st K: 4:22.75
Recovery: 1:00.33
2nd K: 4:20.41
Recovery: 1:00.45
3rd K: 4:21.62
Recovery: 1:00.51
4th K: 4:24.65
Recovery: 1:00.25
5th K: 4:27.25
Recovery: 1:00.54
6th K: 4:29.60
Recovery: 1:00.38
7th K: 4:17.53
Recovery: 1:00.23
8th K: 4:19.19
Total 8K: 42:05.69

I ran in aqua shoes that I'm planning to wear at Sakura Marathon on 25th. They are by far the best shoes for me right now. First, they are super light. For a long-distance runner, every extra gram in your footwear is a cause of energy loss. But my aqua shoes are as light as leathers. Second, they immediately correct any inefficiency in my running form, especially cadence. This is because there is little cushioning in these shoes. You inevitably choose the right cadence where landing shock is minimal. Thirdly, they are damn durable, AND cheap. A pair costs US$10. And I'm still using my first pair that I bought nearly half a year ago. I could add a couple of more merits, but I won't, because if I did, more people would buy them, which can result in a higher price! Just kidding. I'm not worried about that at all. Minimalist runners are still a minority.

My next training will be this coming Sunday. It's going to be my last quality session before the race on 25th. I'm thinking of doing another 2-hour race pace run with periodic surges of varied lengths. I may do something else. I don't know yet. Whatever I do, I must carefully choose to do what brings out my potential most without leaving unrecoverable fatigue.
