Imaginary concept decades ago, became reality. In the early 1900s, the Aga Khan, ruler of much of India, instructed his men to build a trail in North-East Himalayan ranges. He heard great tales of a unique spot, high in the mountains, which bordered present Nepal where it was possible to see four Giants at once and he wished to travel there. The Khan never made it. To this day, much of that same trail still exists as do the Giants.

Retracing the trail of Aga Khan, the event – Himalayan 100 Mile Stage Race was first organized in 1991 with a team of thirteen adventurers and has now grown into a premier mountain race of the world. The Mt. Everest Challenge Marathon commenced during 1994. The guiding philosophy of the race is well planning and excellent support services. Each event makes efforts to create not only new exposure to eco-friendly running but a message on life and nature.

Over the years of its journey, Himalayan 100 Mile Stage Race & Mt. Everest Challenge Marathon (HSR/ECM) has engraved a forte in the realm of mountain ultra races by notch of its spectacular running course and uncompromising ground support service standards, and unique cultural interaction. The event also pioneered into world’s most unique and innovate eco-friendly running events.

A run at own pace with no specific rules, age limits or stage cut off times in five daily stages of 24–20–26–13–17 miles, the entire course of race falls in Indian territory. The altitude varies from 6000 to 12000 ft.
