What's your mile time?

Hey everyone! I'm doing a little statistical poll that compares one's average running mile time to their average swimming mile time. (I realize that is harder...because when we swim a mile straight--generally for us as competitive swimmers we are swimming it in a race and going for pbs...but what I am looking for is more like if you were to swim consecutively for an hour...how many miles would you get in swimming at a nice constant pace that you could withhold for a longer period of time.) And then I would like to compare the level of fitness for your age that those respective would put you at...mostly I am interested in simply seeing the correlation between the two sports, because almost anyone would agree that cross-training is a positive aspect of your swimming regime. My Data: Age: 22 Gender: Female Background: Swimming: competitive swimmer since 4th grade (swam in college all 4 years) Running: no competitive history really (just a few seasons of high school track) like to run...as a 7th grader ran a 6:23.04 mile in the presidential fitness challenge...haven't hit that mark again haha. Swimming: 19:30minutes at a leisurely pace...I've never swam the mile in a meet. Running: 7:40ish at the moment (hoping to bring that down to at least 6:50 over the summer)
