Maybe you don’t have a wetsuit, you don’t like the way they feel, or you don’t want to buy or rent one. Maybe the added buoyancy makes you a more confident, faster swimmer. “Beginners usually approach their first triathlon understanding that they will be wearing a wetsuit because it generally helps them,” Polloreno says. If you want to suit up, find a wetsuit-legal race. If you’re the non-wetsuit type, you may want to look for a race that prohibits wetsuits, or a warm-water or pool event.
