The Marathon des Sables, a multi-day ultramarathon held in the Sahara Desert in Morocco, is adapting its logistics to cope with the increasing challenges posed by climate change. Organizers have confirmed the implementation of enhanced cooling measures for the 2026 edition, including the use of refrigerated containers at bivouacs to store medical supplies and food, and increased ice distribution at checkpoints along the route.
Scientific studies and meteorological data indicate a trend of rising temperatures and more frequent heatwaves in the region, directly impacting the safety protocols for extreme endurance events. The race's medical director has stated that these adaptations are essential to mitigate heat-related illnesses among participants, which remain a primary concern.
The event, first held in 1986, is renowned as one of the world's toughest foot races. While the core challenge of traversing approximately 250 kilometers over six days remains, the organizational focus has progressively shifted towards integrating climate resilience into its operational planning to ensure runner safety.
