Training days could go well or not so well. Today’s did not go well.
Today’s schedule were 2 mile warm up, 2 x 2.5 miles at 7:50 to 8:00 w/4 min rest, 2 mile cool down. And I decided to practice pacing during the tempo intervals.
My split times for the two 2.5 miles intervals were (8:09/7:24,/3:27) and (3:22/8:19/8:41).
For the first mile my time (8:09) was a bit slow. My breath was calm and stride open. So I sped up by pushing my strides, and as expected my breath became laborious. Judging from the splits (7:24 and 3:27 for the half), I over sped.
After the 4 minute break, I tried to find that pace of 7:50 to 8:00 by having running while my breath teetering right on the verge of becoming laborious.
Apparently that did not work so well, and I got tired. My split of 3:22 for the half mile was still too fast. So I backed off and got 8:19 for the next mile. Never could recover my pace for the last mile (8:41).
In hindsight, I might have paid too much attention on my breath. In any events, I need to practice more pacing to get a better feel on managing my pace. So I have a shot at achieving the race I want.
How could you tell what pace you are running?
