Upon starting registration for the Mixed Relay registration type, there is an option at the top to join or create a team. The captain must click 'Create a Team,' type in the team name, click 'Create Team,' then proceed with registration.

The other three team members will start the Mixed Relay registration and click 'Join a Team,' then select the appropriate team and proceed with registration.

In the event of extreme weather, natural disaster, community disaster or other unforeseen emergencies, our action steps will be as follows:

  • USA Triathlon, in concert with local officials, will make the final decision based on safety of the athletes, spectators, vendors, volunteers and others affiliated with the event.
  • USAT may, based on the conditions of the course, shorten the distances or cancel the event altogether.
  • Because costs of the event have already been paid out to cover various levels of production expenses, there will be NO REFUNDS, transferred entry fees or future complimentary entry fees.
