Rebel Race, Greenfield

Rebel Race's military-style obstacle courses challenge athletes from all backgrounds to shed humdrum day-to-day routines to experience the primal joys of mud, sweat and glory. Emerging from the mire in various states across the country, each Rebel Race packs its rucksack with tests of physical and mental toughness, rousing racers and washing machines alike to triumph in the face of sloppy opposition. After dashing through fire, climbing walls, and scaling mountains of hay, race participants bask in the collective kudos of parties, which include live entertainment, food, and beer for purchase. Camping options encourage participants and spectators to transform races into weekend getaways, while awards recognize each day's standout competitors and most-humble mud pits.
