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 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. A USAT Official will be at the event and will be enforcing all USAT rules. It is strongly suggested you visit the USAT website for the complete list of rules and review.

Relay Sprint triathlon is a WONDERFUL way to experience a triathlon if you are not ready to run the whole thing, if you are not capable of competing in a specific leg, or if you just want an opportunity to share something unique with friends or family. A Sprint triathlon relay can be done with 2 or 3 people. The team can consist of all male participants, all female or mixed. Each person does 1 or 2 legs of the race. The timing chip will have a Velcro strap on it and is handed off from one athlete to the next in transition.
