I am hoping to do my first open water swim this summer, its a one mile swim. I was looking at the past results of the event online and I am confused by some of the times. The winning time was 15:30, that is moving pretty good. However there was a 67 year old man who finished it in just over 20 minutes (kudos to him). And 75% of the people who swam it did it under 25 minutes and this includes a lot of 50-60 year olds. Is it possible the course really isnt a mile? Or do I need to ramp up my training?
