Castle to Hanauma Bay TT


Due to USAC forcing our hand in reaction to the COVID-19 situation, we have no choice but to cancel the race for the time being. All participants who have already registered will be issued a refund with the exception of the BikeReg service fee. It's possible that the race will be rescheduled later in the year.

As with previous years we want the be respectful of the small residential neighborhood near our start line. Nobody likes being woken up by slamming doors and loud voices at 6 in the morning when they don't have a reason to be awake. This year we're going to try and do a better job of making sure we don't disturb the neighborhood. To that end here are the RULES:
