20 + 13

Run 33 miles in 10 days.

Challenge Ended: 12/31/13
Need some motivation to get out the door during the holidays? We're challenging you to run 33 miles in the last 10 days of 2013.

Carve out some time to counterbalance the indulgence, because excessive eating shouldn't be the only time you sweat during the holidays.

Don't start 2014 on your heels. Complete this Challenge and push off into the new year from the balls of your feet.
