Electric Eel Low Crawl
A particpant low crawls through the mud on the Electric Eel obstacle while trying to avoid the dangling wires that are putting out 10,000 volts of electricity during this year's Twin Cities Tough Mudder in Hugo, MN. In order to complete most obstacles in the Tough Mudder, participants must rely on one another for team work and support. (U.S. Army photo by Staff Sgt. Cliff Coy)
