Atacama Crossing 2025 in Chile

The Atacama Crossing is a 155 mi (250 km) six-stage foot race held in the Atacama desert in Chile. It is a self-supported ultramarathon, which means that runners have to carry their clothes, equipment, medicine, and food supply for seven days. The organizers provide 10 liters of water per day and the tents for overnight rest. The race consists of six stages: in four days, runners have to make almost four marathons, then cover 74 km in one day, have one rest day, and complete a final stage of 11 km on the last day, finishing in the ancient town of San Pedro de Atacama.

The Atacama Crossing race is part of the 4 Deserts races and is also organized by RacingThePlanet. Other races are the Gobi March in Mongolia, the Namib Race in Namibia, and the Last Desert in Antarctica. The Atacama Crossing has a reputation as the hardest one. During the day, the temperature in the desert reaches 46 °C (115 °F). In the night it drops to 6 °C (3 °F). Atacama Crossing 2025 is expected to attract up to 200 competitors from more than 40 countries.

Runners traverse challenging salt flats (described as frozen broccoli) and dunes, La Valle de la Luna (Valley of the Moon), go through narrow canyons where they can touch both walls at once before arriving at Valle de la Muerte (Valley of Death). There will be river crossings, waist-high grass, Inca and Aymara ancient rock artifacts, and beautiful stars like you've never seen at night.
