Subject: RE: Marathon running and marathon swimmingdude, I don't know........although I tend to think anyone completing an IM marathon in less than 3 hours would be capable of doing a 10k swim in less than 3 hours. So, I think a lot of people could do it without additional training, I just don't think a lot of people are into swimming for 10k though.
For the record, I couldn't do either. |
