I must've been decelerating instead

Friday--took off

On Thursday,  --5:45 AM moderate track workout.  Cold morning--37 degrees, unlike last Thursday's 50 degrees when I did the same workout

Left home at 5:35

Warmed up 1.0 mile and stretched.

Started at 6:03 AM

The workout was 8 x 150.

Goal: 1st 2 in 22 sec; 2nd 2 in 21 sec; 3rd 2 in 20; last 2 in 19 sec.  Rest of 3:00 minutes/250m walk between each.  

1st effort: 23.2.  Oops.  Flat

2nd: 22.3.  Better, more pop.

3rd: 21.2.  Nice.  I began to work on shortening my stride and hitting the track with as many steps as possible sort of.

4th: 21.6 Good.

5th: 20.9 Hmm

6th: 20.5

7th: 19.6  

8th: 20.4  The oddest thing happen.  As I lifted coming down the straightaway, I assume I was accelerating.  I must've been decelerating instead. I did not necessarily feel like I exhausted the tank.

I think that I can go faster by a .25-.5 second or so with better weather conditions and if I do this workout later in the day.
