Tough Mudder returns to Melbourne after a six-year absence, featuring obstacle courses that test participants' strength, stamina and mental grit. Over 7,000 participants are competing in the event, which includes various challenges such as electric shock obstacles and the 'Infinity' course that gives competitors nine hours to complete as many obstacles as possible. First-time participants and teams from local gyms are taking part in the gruelling but popular endurance event.
