Watch the Blokes as they try to conquer Ireland’s Toughest Mental & Physical Endurance Challenge, it’s the country’s largest and most popular obstacle course run. Participants must complete a 8-16KM trail route crossing rivers and lakes, climbing hills and mountains and crawling through bogs and swamps. To survive, you must conquer all the elements thrown at you, whether that is the temperamental weather conditions, the gruelling natural environment or the torturous man-made obstacles.
