I entered the Tri-Raider Sprint at Buffalo Springs Lake. The web site says the water is ~74 F. I think I can do the swim (500 m) without a wet suit as long as I get a good warm up in first. Any thoughts, I plan on doing the swim in Tri-Shorts and maybe an Orca singlet.
Almost everyone wears wetsuit for the race. However the water is borderline if you need it or not. Last time I was there the water was 76.5 degrees.
Most peole do wear one, but I didn’t and was fine.
I did the 1/2 IM distance twice with no wetsuit and it was a little colder than I’d like but fine.
