For Jonathan Rice of Longmont, Colo., it's not enough to just run through the scorching heat of Death Valley, Calif.
He has to do it dressed as Darth Vader.
Last weekend, Rice donned his Vader suit and raced one mile in just over six minutes in 129-degree Death Valley heat.
In fact, Rice has been running in costume for nearly three years. His "Darth Valley Challenge" has grown and is attracting many others willing to dress up in Star Wars-themed costumes for the one-mile sprint through high temperatures.
