May all your miles be merry!
Help support our charity partner, Toys for Tots, and sign up for this Holiday Challenge today. Register to run before December ends, then run or walk your 5K, 10K, half marathon or miles challenge and submit your results by Dec. 31st.
For the 25, 50 and 100-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 25, 50 or 100 Miles of Christmas!
Use #25MilesOfChristmas when sharing your photos from your run!
