One spooky challenge. Run through the haunt!
Help support our charity partner, Ronald McDonald House, and sign up for this Holiday Challenge today. Register to run before October ends, then run or walk your 5K, 10K, half marathon, or miles challenge and submit your results by October 31st.
For the 31- and 62-mile challenges, you do not need to run all the miles at once. Run it when you want, run it where you want, run on a treadmill; any miles count! Our results system will allow you to add up your miles until you reach the 31 or 62 Miles of Halloween!
Use #31MilesOfHalloween when sharing your photos from your run!
