In the event of inclement weather on race day, the Aspen Cycling Club Board of Directors will communicate with the Race Director to determine the Club’s ability to operate a race that is reasonably safe for competitors, and, for mountain bike races, preserves the integrity of local trails. All racers should assume that a final decision will be made at the start line by the race director. However, when possible, the Board of Directors will alert racers of a race cancellation prior to the start by emailing the Club email group, and posting on the website and the ACC Facebook page by 5.00 PM.
