Wetsuit or no wetsuit?
When should i not use a wetsuit for a race?
Is it water temp dependant or are there other factors to take into account?
water temperature dependant
in the UK I would say you will never get the chance to do a race where wetsuit is optional....other than the actual Open Water swim only races. In triathlon you will always wear a wetsuit unless you race abroad.
Given the option, wear the wetsuit, for all but a few it will make you significantly quicker. The only time not to wear it is if they are banned for the event due to water temperature.
I somehow managed to forget my wetsuit when I went to the lake the other day. Decided to go for a cold dip. Swimming with people who I'd normally be 10-15secs faster than over 100m, I was unable to keep up with them whilst I was sprinting and they were just warming up!!! - I was shocked....and cold!
