The One Hundred® Ladakh, Trail to Heaven race stands as a majestic chapter in the grand tapestry of the One Hundred® Trail Endurance World Championship. This endurance high-altitude mountain trail race, set against the awe-inspiring backdrop of the cold desert along the Markha river, from Leh to Stok in the Ladakh region of the Great Himalayas, is not just a race; it's an emblem of human perseverance and spirit. 

Scheduled between the 7th and 9th of August 2025, it challenges participants to push their limits across some of the most breathtaking terrains on the planet. 

The Trans-Himalayan region of Ladakh is a geological and cultural wonder. The name 'La-dakh' translates in English to 'the land of the high passes.' Inhabited by a unique mix of natives and people of Central Asian descent, Ladakh has historically been the gateway for caravans traveling on the ancient Silk Route, connecting the Indian subcontinent to Central Asia.

Most of Ladakh lies above the altitude of 3500 meters (11,500 ft.) and is home to some of the highest mountains in the world, towering over 7000 meters (23,000 ft). The rich culture, stunning landscape, and the element of high altitude make Ladakh a unique spot on our planet for a great endurance challenge.
