First race: Cat 4/5 or Masters 35+ 4/5
I've seen a lot of threads about the difference between Cat 4/5 and Masters but they are usually referring to Masters 1/2/3/4 vs. Cat4. A lot of the local races I've looked into have the option of either Cat 4/5 or Master 4/5, so as an over 35-yo Cat 5, I would have the option of entering either and wouldn't be racing against older Cat 1s and 2s. In most cases the races are back to back, so entering both isn't an option either. Any suggestions?
