I started riding this "weird bikes with the skinny tires and uncomfortable seats" in March of '09, and I was surprised to find I really enjoyed it. I've been riding pretty regular, 3 - 5 x per week, and about 40 mi a pop. Twice I week at 5:30 AM I meet up with some younger guys and we do wind sprints.
I've become a pretty solid B+ rider. Some of the guys are encouraging me to enter local some age class races. I'm 62.5 (I've ridden my metric age several times since my metric b'day) and I can hold my own at 20 - 22 all day in a pace line, and 24+ for about 30 min or so. I can usually find something left to "pour it on" in a short sprint. I just hit a new personal best of 31.4 mph on a slight incline trying to catch a 20 y/o hot shot on an uphill break away.
I really don't know anything about the amature bike racing scene. Does anyone have any experience in this? What are the age classes? I don't think I can be at all competitive in a 55+ age group, but I think I maybe avoid major embarrassment in a 60+ class.
Any experienced senior racers out there?
