Day 3 - Speed Training

My legs seemed to be hurting even more today which didn't bode well for the speed training. I did 6 x 400m at 11.1 kph with 2 minute gaps between each run and by the end I was shattered. The main fear is that this is only week 1 - still, I guess the guy that created the training plan knows what he's doing - doesn't he...?
