Join us on Sunday December 15th for a fun and festive, family-friendly 5K run and walk in the town of Superior - conveniently located off Highway 36 between Denver and Boulder. Get a head start on the holiday season with the Stocking Run!!! The race is limited to 1,000 entrants, and all participants will receive a red felt stocking chock-full of sponsor goodies! How fun is that!!! This is also the first race in the Racing Underground winter running series, which offers some serious prize money for the top finishers and age group awards in every age category. Pick one race, or do all three!
