Short Intervals: 6 Sets by 400 M + 3 Sets by 650 M

Oct.8, 2019

I was too tired to run. This past two days I had a big corporate seminar. The first was in Osaka. And the other was in Osaki. Yesterday I was scheduled to run 10 K. But when I got home from the business trip, I was so sleepy because I woke up at 5:30 that morning. Plus, I was scheduled to have another seminar that was four hours in total. I knew I should save energy for the job. So I hit the bed as soon as I got home. 

Tonight I was scheduled to run, but again felt so sleepy and exhausted to run. I was worried. Absence of training could kill the benefit of the good training on Sunday... I lay in bed for a couple of hours to see how I'd feel when I got up. 

Luckily when I woke up from a brief nap, I was ready to run. But I wasn't in a mood to go for a long monotonous one.  I wanted something nice and intensive, but not too long. I decided to do some short fast reps. I jogged from home to the 400 M stretch and did  6 repeats.

To my surprise when the session was over, my energy was back. I was prepared to do a little longer run. I jogged back to the quarter-pie-shaped loop above and did 3 fast runs around it. The result is shown below:
