In the Zipp High Speed Challenge. Drafting off. Power to the pedal and pedal to the floor. A 23k virtual time trial on a virtually flat course. My legs felt dead for the first five to ten minutes but I gradually got into. With no drafting it's just you and the power. I was in the bottom half of the field at the half way point but by then my moment was building. I gained over a dozen places on the way back, my power increasing, to finish in the top twenty of fifty one. The only downside is that my god damn achilles is still playing up. What doesn't kill you makes you stronger - even if it is very annoying.
