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.
