Who doesn't love a challenge, fierce competition, and extra bling? We present to you, the Chattanooga Challenge! Participate in the 5K on Saturday, and either the Half Marathon or Marathon on Sunday, and turn two medals into three! You'll receive a medal for each race, plus an exclusive multi-race "Chattanooga Challenge" medal!

When registering for the Chattanooga Challenge, you can sign up for both races at once! Select either the Half Marathon - 5K Challenge or the Marathon - 5K Challenge to sign up for both races. After you cross the finish line on Sunday, head over to the Chattanooga Challenge tent to receive your challenge medal. Put that medal on and proudly wear your three medals for the rest of the day!
