Hundreds of mud-covered participants darted from one obstacle to the next as they competed in the grueling eight-mile Super Spartan Race yesterday at Wolfe's Pond Park, as part of the Spartan Race Challenge. Under the Spartan Race banner, there are four different obstacle courses with varying degrees of "extremeness," starting with the Spartan Sprint, then the Super Spartan followed by The Spartan Beast and -- the most extreme -- The Death Race.
