The race's website ominously announces, "You won't die. Serious injury is unlikely. However, there's still a good chance you'll bleed a bit." Participants are pounded with high-powered water guns (used to create snow during the ski season), dive through rings of fire, and run through other obstacles during their 10-mile race, so that warning should be taken seriously. Nonetheless, every year 1,000 racers join in on the fearless fun of Maine's Tough Mountain Challenge.
