Prop bet - 5 minute mile

[HedonismBot]

I'm coming up with some sort of prop bet with my room mate on me being able to run a 5 minute mile by mid may (7 months). I'm a lean guy (6'0 160 pounds) and have been athletic in the past (playing hockey) but for the past 2 years have been out of shape. I've never ran more than a few miles and that was a slow pace. I ran a mile a couple times earlier this week at about 9 minutes each without really trying too hard, I bet I could run about 7:45 if I gave it my all.

How hard will it be for me to do this? I am sure that it's possible but don't know how to go about getting started. Also we're at 6000 feet if that makes a difference. Thanks for any advice or links for how to train [img]/images/graemlins/laugh.gif[/img]
I'm gonna go run now and will let you know my time
