200 km across the Atacama: Ray Zahab on survival, heat, and the edge of human limits

"The thing about desert expeditions that really takes you by surprise is how quickly things can go off the rails. It goes from good to bad almost instantly. In those moments, I remind myself: I chose to do this."We’re excited to be joined again by Ray Zahab, an ultra-endurance athlete, public speaker, author, and RCGS Explorer-in-Residence, among other things. In this thrilling episode of Explore, Zahab takes us through his latest expedition across the driest desert on the planet: Chile’s Atacama. Running a marathon a day over 200 kilometres in extreme heat, Zahab traversed over brutal terrain with constant risk. Carrying minimal gear and relying on cached water, he and his teammate, Stephano Gregoretti, pushed through deep sand, steep climbs, and temperatures that regularly topped 45°C. Along the way, their journey took an unexpected turn when they took part in a real-life rescue in the Andes.This episode also touches on one of Zahab’s favourite endurance films, Running on the Sun, a cult-classic documentary from 2000 about the Badwater ultramarathon that captures the mindset behind pushing human limits.This is a powerful conversation about resilience, decision-making under pressure, and the mindset required to endure when things go wrong. And a special thanks to long-time listener and friend of the podcast, Aran O'Carroll, who sent in a very thoughtful question for this episode. Zahab has a great answer towards the end.If you enjoyed this, check out Episode 104 with Zahab and RCGS Fellow Kevin Vallely on their self-supported winter ski expedition across Ellesmere Island, Canada's most northerly Arctic island. About Ray: Ray Zahab (@rayzahab) is a Canadian explorer and ultra-endurance athlete known for completing some of the world’s toughest expeditions, including running across the Sahara desert and a record-setting expedition by ski to the South Pole.
