I did a metric century this past Sunday. The wind was blowing hard all day and at the end and was always against me on the hills (yes, these were actual hills in Illinois ... well, anthills if you're in Colorado) for the last 20 miles it seemed. I didn't feel the pain so much as I felt anger! For some reason, I just got really pissed off and shouted at the wind up each and every hill for that last stretch! I was in the 39-23 and had nowhere else to go ... should have got the tripple!
