Saddle is fine. I was really sick last weekend, and the day before yesterday I took my first long ride since being sick. Lot of climb on that ride too. I reckon that has something to do with it. And it has been fairly cold here lately. High 20s last night, low 20s tonight. The only other thing different from the norm is I started wearing nicotine patches yesterday... trying to quit. I also have really cut down my coffee consumption to help quitting smoking, but I think that should be a good thing as far as hydration goes. Probably just pushed it too hard Thursday after being ill.
