Starting August 26th, 2011, Ray joined friend Will Laughlin to run the length of Death Valley- from north park boundary to south park boundary. The distance was close to 250km, and the duo relied on water re-supply every 10-25km during the entirely off-road run.
Ray tested gear, new technologies and foods he will use in upcoming expeditions- most importantly for a January attempt to run 2,000km across Saudi Arabia (back-up plan Kalahari). During the run, the duo carried emergency supplies, food and fluid required for each 10-25km section. Running packs were heavy with 7-8 liters of fluid required for each leg.
