That depends on the triathlon and whether or not it's an openwater swim usually. If it's an openwater swim, generally the water isn't warm enough for a long distance swim (Ironman 70.3 or full ironman distance) with just a tri suit. That said, some triathlons are held in pools or warmer bodies of water where it's warm enough to not need a wetsuit. That said, most athletes still wear their tri suit under their wetsuit during the swim so you just to strip off the wetsuit for the bike section of the course.
I wish you had a MIC
Haha I'm sorry! I've since improved my setup . I didn't know exactly what I was doing :/
Do I need a wet suit or can I just use my tri suit the whole race?
