The Manali-Leh highway, a heaven for thrill seekers who descend on its circuitous roads every summer, is arguably one of the toughest roads to conquer, going through some of the world&rsquos highest mountain passes. On September 25, at an altitude of 2,000m on the famed highway, Sufiya set out to push her physical limits, on foot. The ultramarathon runner completed a gruelling journey of 430km, starting from Manali and ending in Leh, and became the first female runner to achieve this feat.
