I've just gotten into track riding fairly recently. I completed 4 levels of California Superbike School this spring/summer and have done several track days at the local track. I've spectated at WERA and CCS club races and can't get the idea out of my head that I'd like to give that a try one day. Problem is, I'm 53. Stuff that didn't used to bother me much hurts a lot now - like crashing. So I'm wondering how many people my age are actually out there racing. What's the consensus on how old is too old to start?
