This past weekend was the running of the annual Tough Guy race in the English countryside, which touts itself as the "toughest race in the world." It looks pleasant.

The Tough Guy race features the same sort of obstacles—mud, cold water, electric shocks, more mud—as office-team-building favorites like Tough Mudder, but magnified to a far more insane level of intensity. The video clip above, filmed by a documentary team, shows James Appleton, who has won the race three times, finishing up this year (he came in third). If you've ever wondered what serious hypothermia looks like, here you are. It finishes with this exchange:

OFF CAMERA VOICE: "Will you tell me why you run this?"

SHIVERING HYPOTHERMIA-WRACKED GUY: "Uh..." [EXTREMELY LONG PAUSE MARKED BY INVOLUNTARY TWITCHING], "I don't really know any more."

Maybe just do some pushups and stuff.
