USAT, or USA Triathlon, is the national governing body of the sport of Triathlon. Sanctioning an event through USAT means the race is provided insurance for its athletes, race coordinators, and volunteers. As a sanctioned triathlon, all athletes are required to either be an annual USAT member or purchase a one-day membership pass. If you are currently a USAT member please make sure to bring your proof of membership when you pick up your packet. If you do not bring this proof, you will be charged for the one-day membership fee. If you are not an annual member, you will need to purchase a one-day membership (to insure you as a triathlete) before you are able to pick up your packet. One-day membership will be collected when you register online.
