The Triathlon/Ironman Training Thread 2025

What advice do y’all have for cold weather races? Coeur d’Alene looks like it’s going to be cold this year: low 45ºF/7.2ºC, high 60ºF/15.6ºC, 55% chance of rain. Water temperature is currently 68ºF/20ºC.

I’m less worried about the swim, with these temperatures a shortened swim is possible (or cancelled altogether, if the lake turns over and the water temperature drops). I’m more worried about hopping on the bike wet in those temperatures. I’m thinking:

  • Skip the one-piece trisuit, wear tri shorts for the swim and put on a long sleeve jersey in T1
  • See if I can buy a gilet or rain jacket this week, or at the race expo, in case it rains
  • Wear full-finger gloves and/or toe covers

Anything else I should think of? Open to any tips.
