Over the month of January, runners will be challenged to complete a mileage goal that goes beyond their typical comfort zone–  25, 75, 150, 225, or 300 total miles. We've also added a new 'unhinged' challenge -- for those who want to take on more than 300 miles. Track your mileage through this website as you go, and once you've reached your distance, the challenge is complete.

EVERY SINGLE WEEK we're giving away THREE pairs of ASICS shoes and a Polar GRIT X GPS watch! GRAND PRIZES include ASICS Shopping Sprees, Polar Vantage 2 GPS watches + heart rate monitors and a special BITR Swag Pack to the participant who completes the most miles!

GRIT starts in...
