Are you tough enough?

Every year, thousands of tough men and women attempt the grueling 8-mile-long assault course, which boasts 25 daunting obstacles such as fire pits, freezing pools of water, muddy trenches and more.

First staged in 1987, the infamous race is so challenging that up to one third of all participants never make it to the finish line.
