11.4 K Barefoot Jog
Mar. 27, 2021
11.4 K: 1:02:06
I went for an easy run for an hour. I ran in bare feet. Nothing gives me a better feeling. It was absolutely awesome. Winter is over. There is no need to worry about frostbite. Legs felt light. A cold feeling of the evening asphalt on the sold is a constant reminder of the physical endurance that I have developed over the last few years. I'm so glad that I didn't give in to the initial discomfort with a barefoot run. Now I feel so free.

I got out in bare feet and ran for about an hour. The temperature was 2 degrees Celsius when I left home, and had dropped to below zero when I got back. Cold, but it was bearable.

After coming home from work, I wanted to a short lecture by Brian Tracy. I have an important corporate seminar tomorrow. I wanted to get some useful information from the world-renowned motivational speaker.
The temperature was -1.9 degrees Celsius when I left home. I had bundled up expect for my feet which had nothing on.

Midnight Barefoot Jog & Body Weight Muscle Training
Dec. 18, 2020
I got out in shoes. But it didn't feel right. So I returned home, kicked the shoes off, and hit the road again. This time it felt right though in no time both feet got numb from the freezing cold. The sky was so cloudless, and the stars were beautiful. The Winter Triangle is always the first one to greet me. It's so majestic. I like it when it looks as though it hadn't moved a bit when I return from an hour-long job.

Midnight Barefoot Jog Combined with Body Weight Muscle Training
Nov. 18, 2020
It was warm for the season. I dressed lightly. It's been a while since I last hit the road in bare feet. The course tonight is very poorly-maintained, and not very friendly to a barefooted runner. But nevertheless I went out without shoes, because I wanted to test my endurance. Or to be more precise, the endurance of my soles.

Sunset Park Barefoot Jog
Nov. 8, 2020
Woke up a new man after sleeping 10 hours straight. Had a huge breakfast of hotpot with anglerfish I had bought from a local store. It was significantly marked down.
Watched Japanese chess on NHK later. Defending champion Mr. Fukaura beat Mr. Ayumu Matsuo with 104 moves into the match.
Studied Spanish for one hour. Then watched "Sleepless in Seattle" for about 30 minutes when the sky started turning orangish from blue. Decided to hit the park for a jog while still warm.

4 K Barefoot Jog: 21:25.83
Tire Walk 10 sets by 30 seconds with a 15-sec rest between sets: 9:02.79
You raise the tire in the photo over you head and walk for 30 seconds. Rest 15 seconds. Repeat until you hit 10 sets. Easy at first. But it becomes progressively harder as you go through more sets with building lactic acid making it hard to hold the tire above your head. It hits traps and tri-ceps as well as shoulders.

Earlier today news spread across the country that IAAF may change their regulations to ban NIKE's Vaporfly Next%. It's been debated since many former records were smashed by athletes who ran in the NIKE's magic shoes. Some athletes openly attribute their new CRs to the shoes. An official announcement is yet to be made. But other shoe makers that produce carbon-fiber-plated shoes must be worried.
Whatever decisions may be made, fairness of the sport is maintained as long as all runners run under the same regulations. Let's see what decisions will be officially announced.

1-Hour Barefoot Jog
11.68 K: 1:01:46
I ran more than 10 K in bare feet after a long time. I didn't run barefoot much before the race on 15th to avoid injury just before the race. After the race my right foot hurt a little. I gave it a rest awhile. When I ran, I put shoes on. Tonight I finally felt reasonably recovered for the first time after the race, so I test-ran without shoe.

I had my first barefoot run after Ohme. I hadn't run barefoot for almost one month, so I was afraid that my soles had softened, but I could feel when I hit the road that they had actually toughened, and they were almost numb to slight roughness on the road.

Almost forty eight hours after the 42 K run, I found myself pounding the road again, this time in bare feet, and with a 2 kg dumbbell in each of my hands. When I first did it last week, it was hard. Now it feels less so. I am amazed at the human ability to quickly adapt to increased burden.
I carefully checked my running form so as not to damage my soles. Any injury at this stage of preparation will cause a huge setback. I can't let that happen.
Tomorrow is interval night. I may do 1 K by 15 sets inspired by Eliud Kipchoge. Or I may settle for a more moderate session, like 3 K + 1 K recommended by former ultra marathon world best record holder Mr. Sunada. Or I may do something between the two. I will make my choice depending on my mood.

Ran an hour in bare feet. Covered 10.2 K in 1:00:50. Carried a 2 kg dumbbell in each hand to increase the challenge. Another challenge came from running the second half faster, though speed wasn't main focus for tonight's training.
The soles are in pretty good condition after the run.
