Please don’t send questions just to me. This is a perfect one that perhaps someone else might have more specifics regarding Eagleman.
However, since this is a group training program, I will answer the question so it applies to everyone. This is not a straight forward answer. Basically it depends on your specific race. Some races will allow for you to wear them even if the swim is not wetsuit legal. Others will not. Others will have a last wave that anyone wanting to wear a wetsuit can still participate. Others will not let you if it’s above a certain water temperature due to the concern of overheating.
So I encourage you to read the Athlete’s Guide and FAQ’s for your specific race.
