In the event of a sellout, USA Triathlon will create a waitlist for athletes wishing to participate in the Toyota Age Group National Championships. The waitlist is free to join and athletes will only be charged if a slot opens and they are accepted into the event. Note that qualification is still required to join the waitlist for the Sprint and Olympic-Distance National Championships. The Time to Tri Open Waves (non-championship) and Open Water Swim will also have a waitlist that does not require qualification.

Time to Tri Open Waves - No Qualification Required

Event Cancellation and Modification Policy

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. 

Athenas and Clydesdales

Since ITU does not support a division for Athena and Clydesdale at its Sprint and Olympic-Distance World Championships, USA Triathlon does not provide an Athena and Clydesdale division at the Age Group National Championships. If the athlete’s intent is to qualify for either the Sprint or Olympic-Distance World Championships, they will need to compete in the wave corresponding with their age group at the USA Triathlon Age Group National Championships. To qualify for the Age Group National Championships, all athletes will need to meet qualification in their respective age group at a sanctioned event when qualifying.

USA Triathlon continues to support the Clydesdale and Athena National Championships as a standalone event in the sprint and Olympic distances. Additionally, USA Triathlon supports Clydesdale and Athena divisions at most other national championships.
