I swam competitivly for about 5 years but took about a year off of regular exercise. I went out and measured the distance with a surveyer wheel and it was .98 miles so it was a little off when i ran the 6:20's i wasnt exactlly wiped out at the end, what would be a good way to gauge my fastest speed? just go to a track and run a mile as fast as i can or what?
