The Big Picture has shots of the Tough Guy Challenge 2009:

Billed as “the safest most dangerous taste of physical and mental endurance pain in the world”, the Tough Guy Challenge took place yesterday, February 1st, on South Perton Farm, near Wolverhampton, England. Thousands of challengers (men and women) started the endurance race, with hundreds dropping out along the way due to exhaustion or injury – broken bones, dislocations, and over 600 cases of hypothermia. Even the overall winner, James Appleton, was treated briefly for hypothermia.

Did the guy in the Borat suit finish, you think?

I just found, via the Crossfit forums, an Outside article from 2003 on Juliet Draper, a monster competitor at the Firefighter's Combat Challenge. Here's the deal with the course:

Today's racers--some 100 men and two women, all wearing 75 pounds of firefighting gear--will have to lug a 45-pound hose pack up five flights of stairs; hoist another 45-pound hose pack, by a rope, to the top of a stair platform; drive a 165-pound steel I-beam with a sledgehammer; run through orange traffic cones to reach a water-charged hose, which they'll drag 75 feet; and walk 100 feet backward, pulling a 175-pound dummy named Rescue Randy. All this while wearing masks and breathing from the bulky scuba-type air tanks firefighters carry on their backs.

Since then, she absolutely crushed the previous women's world record for the course, at the same time becoming the first woman to break 2:00 (by a significant margin, I might add).
