Midnight 10 K Jog in MUTEKI

Midnight One-Hour Jog in MUTEKI
Feb. 8, 2021
11.4 K: 1:06:11
Jogged for a little more than an hour in split-toe minimalist shoes MUTEKI. Ran the hilly course I use for tempo run. It was deserted and quiet, perfect for listening to an educational program. Listened to the new psychology of selling by Brian Tracy while running. Very insightful. Rich in content that I can share with my clients in corporate seminars.

Midnight Jog in MUTEKI
Sept. 27, 2020
12.7 K: 1:12:01
It's my first run since I got yelled at by a driver while running on the roadway. I kept on the right side of the road, and remained on the sidewalk wherever one was available. The surface was often less smooth on the sidewalk than on the roadway, and the width was rather narrow most of the way, but it wasn't so hard to adjust myself to the new habit of running on the right side and running on the sidewalk. I'll stick to it so as not to piss off drivers, and also to avoid accidents.

I went to see the Tokyo Marathon today. Suguru Osako finished 4th with a new national record of 2:05:29. It was inspiring.
At night I did a 20 K tempo run. It's my first major training session after Ohme. I wasn't sure if I could successfully carry it out. It's highly stressful training. Plus, I hadn't done much training for almost two weeks. But I wanted to know how far I could go anyway.
As I jogged to the start venue, I felt a stinging pain in my knee. For a moment I suspected it might be caused by the stress of the Ohme 30 K Road Race. But the next moment I just shrugged it off, saying to myself, "Well, it's just my sub-conscious saying, 'Don't make it too tough.'" As I look back on it, I think I was right, because once I started running, the pain somehow mysteriously disappeared.
I lapped the 2.5 K loop below. The target for each lap is 12:17. I ran the first 10 K a little faster than the target. Then in the second half it started becoming increasingly tougher to keep the same pace. I was outside the target two laps in a row. There was a tremendous amount of inner-talk, so to speak, regarding whether or not I should continue. I chose to continue, no matter what a miserable self I would have to be facing.
When the target distance was finally covered, and I found myself well inside the target time, I was glad that I didn't give up.

This training is THE most important training for me before the Ohme 30 K Road Race. It's something I've never done before. I didn't do it because I didn't like it. I didn't like it because I was scared of it. I was scared of it because it seemed difficult. However, I finally made up my mind to do what I was most scared of not just because Mark Twain once advised us to do what we're most afraid of, but also because it's what I should do in order to become a stronger version of myself.

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

100-Minute Jog in MUTEKI
Friday, August 30, 2019
10 K Run in MUTEKI
In the final K I increased cadence and put on a spurt. When I stopped my Ironman at the finish, I realized that I ran almost 3 minutes faster in the second half.
It's almost an hours now since I got home from the run. The pain that I didn't feel much while running probably because of adrenaline rush is back. It's amazing that now I must limp just to go to the kitchen from my room, and yet that while running pain was largely manageable. It's one of many wonders of mind-body!

After teaching a 5-hour seminar in Central Tokyo I came home in Chiba around 8 p.m. I had a light dinner, because I wanted to run. On the previous night I ran 10 K by running a 2.5 loop four times. But in the last K of the last two rounds I increased pace significantly. I didn't realize then but tonight when I went for interval training, a consequence of the surge was evident. I barely came under the target of 4:30 right from the first set. The following two sets went all right as I had warmed up after the first. But when I set off for the fourth after taking a minute of break, I felt so weak that I came to a complete halt after going only 20 meters or so. I gave up, because I was expecting to get up early the following morning to teach yet another 5-hour seminar. You got to get your priority straight. Work first. Training next.

Today is the first training day of the second last week before the race. I was originally scheduled to just jog for 60 minutes. But I wasn't too motivated to just run at a slow pace for an hour. I found it too mundane. So I decided to change the pace every 2.5 K, and also to run a different course.

22 K Jog in My New Pair of MUTEKI
11 K: 1:05:23
11 K: 1:00.29
Total 22 K: 2:05:52
Almost 24 hours after doing a weighted 10 K barefoot pace run, I was ready for another training session: 90-minute jog. I asked myself whether I should go barefooted or in shoes. I opted for a shoe-clad practice. There was slight soreness left in both of my soles.
I put on my new pair of MUTEKI split-toe minimalist shoes with no cushioning. NIKE's Vaporfly with thick cushioning is all the rage. But it's not for me. I'm a citizen runner who wants to become a stronger version of himself. Not a professional runner running for a prize money. I want to be faster. But I equally want to be more endurable. More accommodating of discomfort and more resistant to pain.
When I reached the far end of the water plant, I was still full of legs, so I decided to go back the same route that I came from to make it a 22 K session.
