Gotta do a bit more training, will try this next year.
Death Race. Part of the Spartan Races series. Don't know when it starts, when it ends, what you'll need to carry, why you'll need to carry them, or the total distance needed to finish. And the obstacles/tools/everything are different each year.
Seems like it's essentially hiking, with obstacles, and carrying a lotta ****. That I can do. Running I suck at, but hiking I can do forever. Plus I'm too stubborn and stupid to know how to quit.
