This obstacle, by far Tough Mudder’s most infamoust may kill you. The Electric Shock Therapy will sear you with a white-hot blinding live wire. Wires pulsing with as many as 50,000 electric volts dangle over a field of mud that you sprint through.
Hint: Watch out for the bales of hay scattered in various locations on the field. Trip over one of these and you’ll gag on a mouthful of electrifying mud.
