In this extraordinary episode of RunPod, Brig (Dr) J Muthukrishnan welcomes Dr Arashdeep Singh, a physician currently serving in Chennai, whose journey from mountain peaks to marathon podiums is nothing short of legendary.
A qualified mountaineer, Arashdeep began his adventure journey through cycling expeditions and high-altitude climbs. But in 2022, after relocating to high altitude, he discovered a new love—long-distance running. What followed was a test of human endurance in some of the harshest conditions on Earth: frigid temperatures, oxygen-deprived air, and the constant threat of altitude illness.
Highlights from his journey include:
🏅 Guinness World Record for completing the highest frozen lake marathon on Pangong Lake (14,000 ft) in 2023
🥇 Back-to-back finishes in two of the toughest ultramarathons in the world:
Khardung La Challenge (72 km)
Silk Route Ultra (122 km)
