It turns out the toughest obstacle of a Tough Mudder-style race might not be dodging live electrical wires, hoisting logs or leaping over a wall of flames. It might be the nasty stomach bug that can come from swallowing the muddy water.
The U.S. Centers for Disease Control and Prevention issued a memo Friday warning that animal feces in the mud along the courses can give participants a bad case of diarrhea. The agency said nearly two dozen people from the Nellis Air Force Base community in Nevada reported coming down sick after participating in a race in rural Beatty, Nev., in October 2012.
