We have conference meet coming up in a couple of weeks and our coach is wanting us to do a 20x200 workout this thursday. Is this a good speed building workout? I've never had to do so many 200s especially much faster than my mile race pace. Seems like a worthless workout to me.
10 minute warmup
20 minute tempo (no pace, just hard effort but not close to going all out)
20x200 @32s (my mile PR is 4:38) - rest is just jogging across the infield back to the start line and then immediately doing the next 200
10 minute cooldown
