Tough Mudder 2015
When Tough Mudder wanted another flaming obstacle for their 2015 season they called once again on Sigma Services. What was created is the "Ring of Fire." Participants are invited to slide down a pole through the center of the burning ring which has a standing flame of more than a foot and is capable of firing higher. Come feel the heat of the Ring of Fire or the very popular "Fire In Your Hole" slides as you experience Tough Mudder at cities all over the United States.
