Don't know if there's a challenge just like this, i did notice one titled "college football"...but here's the deal:
If you're into football, choose your favorite team (I'm from seattle, so mine is the seahawks).
For every point your team scores, you commit yourself to 10 minutes worth of exercise. So if my seahawks score 13 points in a game, i commit myself to 130 minutes worth of exercise.
Also, for every point they score, you put 1 dollar into a jar. At the end of the season, if you've been faithful with your exercises, you open the jar, and use that to buy yourself something nice!
