I rode my first century (100 mile ride) yesterday. The ride was the Three Rivers Velo Sport Festival Tour. I ended up riding 108 miles because I missed a turn. Nine miles into the ride my rear tire blew. (Not good. I was back on the tubulars because the 130 mm hub didn't work after all. It was my second ride with the new tire.) I rode on an old spare for the rest of the day. About twenty miles from the end, my spare started to go. It was an expensive day, but I managed to do a century.
