On May 29, 2003, on the 50th anniversary of the historic first ascent of Mount Everest by Tenzing Norgay and Sir Edmund Hillary, a group of adventurous runners lined up near Everest Basecamp and ran 26 miles down the Khumbu Valley to Namche Bazaar. The Tenzing-Hillary Everest Marathon was born and has been run every year since.
Recognized as one of the most adventurous trail runs in the world, the Everest Marathon is more popular than ever, and is now complimented by three additional races. The Tenzing-Hillary Everest Ultra 60K is held alongside the marathon in the Khumbu Valley, the Annapurna Adventure Race is a multi-day, multi-sport event in the Annapurna region, and the Lumbini Marathon, a classic road marathon in the Buddhist spiritual center of Lumbini. Together they are known as the Great Himalaya Marathons.
