You need a annual cat 1 license cause it's USAC event. Day of's are good for cat 2/3/fat bike only.Another mtb category question....say someone is competitive in Cat 2, and is thinking about signing up for Cat 1 solely for the purpose of the earlier start time because of plans in the afternoon, would said person be stuck in Cat 1 of they sign up for any future races (USAC or otherwise?)
....and said person doesn't care about points or jerseys, just enjoys attending races when possible and hanging out with cool peeps (and @Mitch on occasion)
