-from the foreword by Christopher McDougal
"Marshall is The Man. Definitively. His run across America at the age of 57 sealed that distinction forever. He's living proof that endurance never sleeps, never gets old, never tires. Nothing can stop him, and that gives us all hope, gives us resolve to keep trying."
-Dean Karnazes, acclaimed endurance athlete and bestselling author of Ultramarathon Man: Confessions of an All-Night Runner
"Marshall and I go way back to the first Eco-Challenge in 1995. An athlete of astonishing grit both then and now, he never fails to push the limits of his sport, no matter what extreme endurance event he's chosen. Running on Empty tells the story of Marshall's greatest test: reading it, you get a sense of how tough this man is, but there's also a bit of Everyman in Marsh. He's an inspiration to all of us." -Mark Burnett, Emmy-award-winning producer of Survivor, Eco-Challenge, The Apprentice, Are You Smarter Than a Fifth Grader and others
