I'm thinking of a workout for tomorrow.  

A workout for you get closer to peak season is only 2 x 200m at race pace (i.e., the 1st 200m speed, about 25-25.5 seconds for me).  Full recovery is recommended to ensure a quality speed workout.

Because I plan to do such a workout early in the morning when my legs are sleepy and my strength is not quite formed, I figured I should adapt the workout to 150s (3) instead of 200s (2).  This would mean 19-second 150s.  Given the 6AM workout, I might have to be content with 19.5 for the 150 meters, which would be 26-second 200m speed.  A 19-second 150 meters would mean 25.3 race pace (i.e., first 200).  An 18.75 150 meters would mean a 25-second race pace.
