The ancient ‘Silk Route’ across the Karakoram pass connected North West India with Central Asia from Yarkhand, Kashgar and Turkestan. This route was strategically important and one of the longest trade routes in ancient time. It was not only an exchange of commodities but also a cultural exchange of customs that took place till the mid 20th century as this is seen in the rich cultural heritage that Ladakh has to offer. As this famous Silk route passed through the Nubra Valley (Ldumra – the valley of flowers), this race has been aptly name the Silk Route Ultra.

This ultra race is for all those who have been running the Khardungla Challenge for several years and for those ultra runners and Ironman athletes who always want to test their endurance further.

Number of participants to this race is restricted to a maximum of 60 runners. This ultra race is scheduled for Thursday 5th September 2024, starting from the village of Kyagar.

An extension and part of the Khardung la Challenge route, this race begins in the little village of Kyagar (3140 m) in Nubra Valley, also home to Chewang Motup Goba, the founder of Ladakh Marathon. Passing through the village of Kyagar, the course takes you up to Samstaling monastery from where you descend through the backroads of Sumur village to Sumur Chowk. From Sumur Chowk you run along the ancient Silk Route (now the Leh- Nubra highway) to reach the bridge on River Shyok. You then run uphill to the village of Khalsar (3264 m) where the Indian Army has a base. Leaving Khalsar behind it is a gradual ascent to the village of Khardung (3975 m). From here on you will be running alongside the runners of the Khardungla Challenge across the Khardungla pass (5370 m) to Leh town.
