USAT Wetsuit Rules

All Epic Races will follow the wetsuit guidelines set forth by USA Triathlon. Those guidelines state:

  • USAT rules state that competitors may wear wetsuits if the water temperature is 78 degrees or lower.
  • USAT rules also state that if the water temperature is between 78.1 – 83.9 degrees, competitors may wear wetsuits but will not be eligible for awards.
  • If the water temperature is 84 degrees or above, participants may NOT wear wetsuits.

Wetsuit requirements and recommendations for temperatures below a certain number are for safety reasons.

  • If the water temperature is below 65 degree a wetsuit is recommended for any competitor. Any type of wetsuit may be worn, (Long John or Full Suit).
  • If the water temperature is below 58 degree a wetsuit will be mandatory for any competitor.  Any person who is not wearing a wetsuit will not be allowed to compete. (any wetsuit is acceptable)
