I have been impressed with the outstanding performances of Olympic runners despite the scorching Tokyo temperatures and oppressive humidity. Inspired after watching the women’s marathon on Friday morning, I decided to see what time I could record for my regular 5K walk/jog through our Tokyo neighborhood.
The temperature was 32○C (89.6○F) with 70% humidity at 10:30AM, sunlight filtered through a heavy cloud cover.
Although weather conditions have caused me to curtail outdoor exercise activity, to my great surprise I clocked a 5K Personal Best time of 45:08. My split times were 9:30, 8:50, 8:59, 8:49 and 8:49. Since I did no jogging the first kilometer, limited my jog intervals to roughly 30% for the other four segments, and did not finish with any “sprint,” I was pleased with my performance.
A new pair of ASICS running shoes with features that are perfect for power walking really helped.
This fall, I plan enter some local 5K races to measure my improved fitness level and relative age group performance.
