Running Prop Bet

[djk123]

Okay.. I wasn't really sure where to post this, but OOT seemed like the most appropriate place. My friend who also plays poker and I like to bet on various crap. The other day the topic of running comes up, and he eventually bets me that I could not run 5 miles without stopping in 45 minutes (on a regular track).

A little background: I ran cross-country my freshman year in high school. I was decent but nothing special. My best time was 20:xx (5k or 3.1 mile race). Fast forward 4 years later, and I am incredibly out of shape.

I thought I could definitely do it in 45 mins with the $$ incentive, but yesterday I was talking to my friend who used to play soccer competitively, and he said that 45 mins would have been very hard even for him back when he was playing soccer and tennis year-round.

So, do you think 45 mins is reasonable? Or should I try for more time? We havn't shook on anything yet, so nothing is set in stone.
