I'm a NTPer and just wondered if it's cold enough for a wetsuit what about the parts that stick out. Thanks.
They'll be cold at first but similar to running, (and to a lesser extent, biking, other activities) if your core is warm and you're moving/are active, you're fine.
FYI: The number 1 reason why you see folks wear wetsuits at races isn't because of the coldness of the water. It's for speed reasons. There are very few triathlons where cold water is big enough of an issue where wetsuit is required. When water temp is below a certain threshold, athletes are required to wear one. That scenario happened at Ironman Sweden last year.
Also, gloves are always banned during races, no matter the water temps. Booties are only allowed if the water is below a certain threshold. I believe that threshold is somewhere in the upper 50s.
