Rugged Maniac 5K Obstacle Race sends runners into an obstacle-filled odyssey of muddy endurance. The 5-kilometer course meanders through more than 20 obstacles, with participants undertaking such punishing feats as scaling 16- to 20-foot walls, crawling through mud-filled trenches, and preventing swinging tires from reforming into the Michelin Man. Waves of no more than 350 runners start every 15 minutes, keeping the track from developing human traffic jams. After the race, live music and cold beer invite triumphant runners to unwind. Those with excess energy can head over to even more kinetic activities such as mechanical bull riding, tug-of-war, and adult-sized bounce houses.
