The 2018 Volcano Marathon takes place on 9th November 2018.
Competitors will assemble at San Pedro de Atacama in the heart of the Atacama Desert, the driest desert in the world.
The marathon will begin near the Tropic of Capricorn adjacent to Lascar Volcano, one of the most active volcanoes in Northern Chile.
At a start altitude of 4,475 metres (14,682 feet), the Volcano Marathon is the higest desert marathon in the world. The impact of thinner air will be felt by competitors, but there is another certainty: the spectacular, panoramic views of up to 10 volcanoes will leave them breathless.
The first half of the race takes place on dirt roads at an average of over 4,000 metres altitude, with manned aid stations at the 10km and 21.1km points (half- marathon).
On reaching the third checkpoint at 30km, athletes ascend 2km off road. At 35km they encounter rough terrain for 5km alongside a gorge and need to pick their step carefully in this section.
The finish line is located at an altitude of 3,603 metres (11,821 ft) where the temperature could be 25C+.
