Spartan Race Hawaii
With new races popping up weekly in cities around the world, the organizers of the Spartan Race are almost as busy as their race's runners. Almost. The grueling races range from the Spartan Sprint, which is a 5K with more than 15 obstacles, to the Ultra Beast, which is a marathon with more than 50 obstacles. Depending on the race, the obstacles may include mud pits, pugil sticks, or fire. To unite the sprawling operation, Spartan Race tracks racers' point totals on its online-standings page.
