I did this last year using the Endomondo App for tracking. It was a bit of a pain remembering to start that for every ride and make sure my phone battery was charged enough for the tracking.

This year - since I started my longer commute in mid February - I've been wearing my Garmin 405 Forerunner. It looks like I can use Endomondo to automatically pull in my rides from Garmin and use that for the challenge. As long as that works I'm in.

But like others noted, I don't see any sort of local leaderboards. I'm the only one at my workplace who rides, so no team here. I guess I'll just have to see how I do on the national level.

Mostly I just hope to win a year's supply of toilet paper. That seemed to be the best award last year.
