I'm 54 and though I only do one citizen race a year, it is a great way to see what your made of. In group rides you never know if the guy next to you is giving his all or just along for the ride, but when its a race you know that guy is trying his best to kick your a##. Train as well as you can and then put in a better effort torward next years race, you'll do it again I garuntee it, once bitten you'll be back!!
