Six Hours: Running For My Life in the Grand Canyon tells the true story of one man's attempt to defy the odds and run the Grand Canyon as a 64-year-old cardiac patient with multiple stents in his "widow-maker" aorta. It's 17 treacherous miles to the bottom and back up to the South Rim. Ultimately, the high-risk run becomes more than an athletic endeavor, as it compels him to reflect on his life, his mortality, and his legacy.
