Newbie Challenge?

So this "Challenge Me" forum intrigues me. I have motivation to train and workout, but I think it would be more fun with a challenge. So that being said, anyone have any ideas or interest in some sort of challenge for a group of newbies? I'm in the process of getting fitted and buying a road bike, so for the time being a cycling challenge is out of the question for me (unless it's a time challenge i can do on the indoor cycles at the gym). Anyway, I think we should get something started. Best of luck to all you new folks out there...and you veterans too.
