Heat Stress / Water Temp / Triathlons and Kestrel

Triathlons and Kestrel

Kestrel Meters are a great handheld meter for all triathlons.  Checking heat stress as well as checking the water temperature to determine if a wetsuit allowed.  All Kestrel Meters that have the ability to measure temperature, can check water temperature.

It's not meant to go deep or withstand deep sea pressure, but an arms length depth is perfectly safe to use a Kestrel.

The ideal meter is the Kestrel 5400 as seen set up on a tripod at many triathlon events.

 

Professional and Age Group wetsuit cut-off temperatures:

  • Wetsuits are allowed to be worn for Professional athletes in water temperatures up to and including 71.5F/21.9C.  Age group athletes will be allowed to wear wetsuits in water temperatures up to and including 76.1F/24.5C. (Note: that for U.S.A. Triathlon sanctioned events IRONMAN reserves the right to allow athletes to participate in the non-competitive wetsuit wave for water temperatures 76.2F/24.55C and up to 83.8F/28.8C)

 

USAT / Series Wetsuit Rules

All Set Up Events Series 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.

For Set Up Event Series scoring purposes:

  • If the water temperature is 78 degrees or lower everyone will receive series scoring points.
  • If the water temperature is between 78.1 - 83.9 degrees and you elect to wear a wetsuit, you will officially receive "0" points for that event. The event will count towards the minimum number of required events to become eligible for awards.
  • If the water temperature is 84 degrees or higher, no one may wear wetsuits and everyone will receive series scoring points.

Set Up Events has wetsuit requirements and recommendations for temperatures below a certain number 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, (John or Full). 
  • If the water temperature is below 58 degree a FULL wetsuit will be mandatory for any competitor.  Any person who is not wearing a FULL wetsuit will not be allowed to compete.

Expected water temperatures will be posted leading up to the event.

Using a snorkel at Triathlon events is also permitted.  See USAT Rules on snorkel use or options for fresh air snorkel options.
