5,799 m / 19,024 ft
World’s Highest Altitude Road Ultra Marathon
Location: Leh, Ladakh
Himalayan Region: Trans Himalayas
Conducted on one of the highest motorable passes in the world, this race exists at an altitude where oxygen availability is critically low and decision-making is continuously impaired.
Oxygen availability drops below 50%. Pace becomes irrelevant within minutes.
Sudden wind, snow, and temperature drops can occur without warning.
Evacuation is complex. Self-awareness is a survival skill.
The Umling La course is designed to expose runners to sustained extreme altitude rather than technical difficulty.
There are no fast sections. There is only controlled movement, oxygen management, and constant self-assessment.
Medical decisions are final and non-negotiable.
