I'm sore, bruised, and my bike is scary dirty. I guess that's a sign of a good ride. :-) On the other hand, I didn't sleep well and I need to keep the crashing to a minimum from now to the race so I don't make things worse.
So the question is whether or not its reasonable to assume that the changes I've made for this year, other things being equal (i.e. trail conditions, etc), will result in an average gain of 1 mph or more.
