The Ladakh Marathon offers a one-of-a-kind experience for runners from across India and the globe, allowing them to race alongside local Ladakhis through a historic Buddhist kingdom navigating the challenges of modernity. The event takes place in the breathtaking landscapes of Leh, where participants traverse the majestic Indus River and conquer the legendary Khardung La Pass from Nubra Valley, creating unforgettable memories. As the world’s highest marathon, it proudly stands as a certified AIMS (Association of International Marathons and Distance Races) event, securing its place on the international running calendar.
Among its six challenging races, the Khardungla Challenge and Silk Route Ultra stand out as the highest and toughest ultra-marathons in the world, testing endurance against extreme altitude and rugged terrain. Held annually in September, this marathon is not just a race—it’s an adventure of a lifetime.
Silk Route Ultra (122 KM)
The ancient Silk Route, once winding its way across the Karakoram Pass, connected northwest India with Central Asia—linking regions like Yarkand, Kashgar, and Turkestan. More than just a vital trade corridor, it served as a vibrant artery of cultural exchange, bringing together goods, ideas, and traditions. This rich legacy continues to echo through the cultural heritage of Ladakh.
Passing through the stunning Nubra Valley—also known as Ldumra, the “Valley of Flowers”—this historic route is the inspiration behind the Silk Route Ultra.
This ultra marathon is designed for seasoned runners, including veterans of the Khardung La Challenge, ultra-distance enthusiasts, and Ironman athletes eager to push their endurance limits even further.
Participation is limited to just 60 runners, making it an exclusive and unforgettable experience. The race is scheduled for Thursday, 11th September 2025, and will flag off from the scenic village of Kyagar.
The Khardung La Challenge (72 km)
The Khardung La Challenge (72 km) is recognized as the highest ultra marathon in the world. Renowned for its difficulty, this race stands as one of the most grueling endurance tests on the planet—designed for elite athletes who are ready to push their physical and mental limits to the edge.
With nearly 60 kilometers of the course unfolding at altitudes above 4,000 meters (14,000 feet), the race demands exceptional fitness, high-altitude experience, and unwavering determination. It’s not for the faint of heart—only the fittest and most seasoned runners need apply.
To maintain safety, quality, and an elite experience, participation is capped at 300 runners. The 2025 edition of the Khardung La Challenge is scheduled for Friday, 12th September, ensuring focused logistics and a premier racing environment for all competitors.
Ladakh Marathon (42.195km)
Running a Marathon is itself a challenge but running the LADAKH MARATHON (42.195km) is even a greater challenge. A tough race at a high altitude, the Ladakh Marathon is not for those with no experience in running marathons but for those who have had dedicated themselves to several months of training. Individuals new to running should begin with a shorter distance and then move up. If you are a serious long distance runner this will be one race that will be a “must do” and one that you will always remember and be talking about for a long time to come.
Half Marathon (21.0975km)
The 21.0975km Half Marathon takes you through the outskirts of Leh and includes a loop that starts and ends at the NDS Memorial Stadium grounds. If you are not ready for the full marathon yet then running the half marathon first helps you prepare for the marathon. The beautiful race course is known for being particularly tough, despite being comparably shorter than the full marathon
