Devil's Shadow is a winter race on the trails of Mendon Ponds Park on February 6, 2027. The race is in the tradition of Cast a Shadow, but with no snowshoe option. The 50k race starts at high noon. As racers loop around Devil's Bathtub, shadows will grow longer and longer until the sun recedes behind the glacial eskers. But you are not alone in the darkness. At the end of each loop there is a warm lodge full of warm people waiting to give you a high five and a mug of something good.
Prices:
-
5 mile: $25 registration fee (+ $3.50 in UltraSignup fees)
-
25/50k: $40 registration fee (+ $3.50 in UltraSignup fees)
-
No price increases. Same-day registration available.
New in 2027
We have re-branded the 5-mile race the "Eat Ice Cream For Breakfast" 5 miler. Participants will be able to enjoy post-race ice cream by the cozy fire - preferably while watching the 50k runners complete loop after loop after loop.
