Course & Elevation
The world's highest marathon starts at Gorak Shep (5,364m), the basecamp support area for Mount Everest climbers, and descends through the Khumbu Valley along trekking trails. Runners traverse alpine meadows, ancient prayer flag-laden pathways, and Sherpa villages while acclimatizing to extreme altitude, finishing in Namche Bazaar (3,440m). The race combines breathtaking Himalayan scenery with severe altitude, thin air, and challenging mountain terrain.
