I am racing in a local tri on the 4th. I don't believe it is a US Tri event and I think wetsuits are allowed. It has been very hot and water temps are pretty warm. I have a full QR wetsuit and am not the strongest swimmer. The wetsuit helps me a fair amount. The swim is 1/2 mile. How warm is too warm to swim in the wetsuit? I don't want to get over-heated, but I also don't want to swim without it if I don't have to. Any thoughts?
