23 Incredible, Grueling Images From An Ultramarathon Through Death Valley

96 competitors gather at the starting line on Monday morning.

It typically takes just over 24 hours to win the race.

Aside from the extreme heat, dust and strong winds are a common obstacle.

Scotland's Chris Moon lost an arm and a leg while clearing mines in Mozambique in 1995, and this was his fifth time running Badwater. The 50-year-old's previous-best finish was last year's 41 hours, 50 minutes. He finished in 45 hours, four minutes this time around.

Death Valley's average high in July is 116 degrees Fahrenheit.

Keith Straw, 58, running his fifth Badwater. (Yes, he's wearing a tutu.)

The Badwater 135 ends at Mt. Whitney, meaning the race has a cumulative vertical ascent of more than 13,000 feet. Severe back pain is one of several common ailments that arise for runners.

Shannon Farar-Griefer, 52, of Hidden Hills, California (lying down), was competing in her seventh Badwater. She reached the second checkpoint at Stovepipe Wells (41.9 miles) in 11 hours, 45 minutes, but dropped out of the race shortly thereafter.

Oswaldo Lopez, 41, of Madera, California, gets a much-needed splash in the face — runners are allowed to have support teams. He would finish in third place, 49 minutes behind the eventual winner.
