Marine trains in hot box for desert "Badwater Marathon"

This training capsule puts every other man cave to shame. Where the treadmill is covered in dust at your house, sweat rains down on Clark’s.

The Badwater Marathon is the Everest of the running world. It’s the reason Clark goes through the grueling routine.

The space heaters mimic the unrelenting sun and the thermometer reads 120 degrees. It sounds like hell on earth and goes 135 miles through mountain ranges.

Ironically, his wife’s name is Angel. “I need to hear, ‘Hey, you need to get up and go’. She doesn't give me a lot of mercy,” says Clark.

Neither does death valley so training is no less than an hour a day in the box, getting his body used to the heat as much as the distance.

“It doesn't matter who you are out there. If you don't put in the effort it will show,” Clark pledges.

This is not only his passion as an athlete but his heart as a Marine. The run is a fundraiser for a veteran’s memorial to be built in Wichita but at the end of the day, Clark says it is a personal challenge.

“I like to see how far I can possibly push my body,” Clark says.

Tony Clark is out to prove what he can do. You may call him crazy but you can’t call him a quitter.
