Instead of doin your boring same old triathlons try Tough Mudder.
Its a seven mile obstacle course, running through a mud swamp, snow pit, and trails carrying logs; shimmying across a lake on a rope; and a navigating underwater tunnels. The finale is racing through a ring of fire. Now thats exciting.
Last race 4500 people attended. You can try it out this year.
