Ray Zahab is the perfect example of an endurance athlete.
  • After Ray Zahab was diagnosed with lymphoma, he plans to run 111 miles in Death Valley.
  • Zahab, an accomplished ultrarunner, kept training in between chemotherapy treatments.
  • Temperatures in Death Valley can reach over 120 degrees, but Zahab says he's ready.

Ray Zahab has run hundreds of miles across deserts and the Arctic, completed numerous ultramarathons, walked to the South Pole, and even starred in a film Matt Damon produced about Zahab's 111-day trek across the African desert with friends.
