SadieKate - It was definitely the sit bones...and the next day. I don't remember having too much soreness after the 110 weekend last year, so I think you are probably right and I just need more saddle time.

Of course...a new bike that fits me better will be a plus, too! I think we'll be ording it tonight after work! Yipee!!

Bikegoddess - I've heard that about chocolate milk! I don't really do dairy, but I'm tempted to give that a shot! I will say that I'm crazy-insane about my water bottle...so hydration when I'm not on a bike is a piece of cake for me. I drink water like it's going out of style!
