Abebe Wannabe's 10 Sets by 1K Barefoot Hill Repeats

I did 10 sets by 1 K hill repeats without wearing shoes in order to further improve my running efficiency. I first jogged around my house for about ten minutes. I then headed for my favorite 1 K hilly stretch 1.7 K from home. I did 10 sets of 1 K hill repeats there. After that I jogged back home. I didn't measure the distance during the first 10-minute jog, but gathering from the time, it's probably somewhere around 3.5 K. The detail of the practice tonight is as follows:

Warm Up: 19:05.36
1st K: 5:27.65
2nd K: 5:24.45
3rd K: 5:23.97
4th K: 5:17.11
5th K: 5:18.57
6th K: 5:23.25
7th K: 5:15.11
8th K: 5:12.74
9th K: 5:16.70
10th K: 4:55.95
Warm Down 1.7 K: 9:35.87
Total 15.2 K: 1:21:36

I feel my soles have gotten tougher. The texture of the road was occasionally rather coarse, and it hurt a little. But that wasn't unbearably painful. I felt like I could go on even after doing ten repeats, but I stopped. My cardio was still strong, but the soles started feeling slightly sore. A blister would prevent me from training. So I called it a day.

I feel much more confident about running barefoot. I might go for a test run on the course of Gas Light 10 K Road Race held in Yotsukaido this coming November. I test-ran the course last year, but there were so many small edgy pebbles on the road, and I gave up within 5 minutes of starting off. Maybe this year my soles have gotten strong enough to run through the bad condition.
