All throughout highschool the only running I did was for Civil Air Patrol, who's only measure was the mile run. Best time then was 6:23. In college I was broke and bored, so I spend lots of time at the fitness center. Got my mile to under 6 minutes (didn't have a precise clock). A few weeks ago I became irrationally afraid of having one of those heart attacks that happen to young skinny dudes who aren't in as good of shape as they think, so I started running again, going for distance having never done it before. Just hit 2 miles in a single streach, probably the furthest I've run without a break.
