August 27, 2025

St Paul, Minn. (August 27, 2025) /ENDURANCE SPORTSWIRE/ – 3M Thinsulate™ and Scotchgard™ were thrilled to sponsor the Everest Marathon 2025, held on May 29. Known as the world’s highest marathon, the event saw elite athletes tackling the formidable terrain of Mount Everest.

Held every year since 2005, the Everest Marathon is considered the most extreme marathon on Earth. Runners face thin air, freezing temperatures, and unpredictable Himalayan weather. It was more than a race—it was a test of human endurance and a showcase of cutting-edge performance gear.

“The Everest Marathon is the ultimate proving ground for both athletes and gear,” says Melissa Blakley, 3M Thinsulate and 3M Scotchgard Global Portfolio Director. “Our mission is to ensure these runners have every possible advantage because at 17,000 feet, there’s no room for error.”

For the 2025 Everest Marathon, 3M collaborated with China’s top outdoor brand KAILAS and top designer Rico Lee to create high-performance gear. Runners relied on 3M Thinsulate for lightweight warmth, Scotchgard for moisture protection, and Scotchlite for visibility – technologies that proved vital in extreme conditions.

The race featured gear specifically created for athletes, including outdoor jackets, padded jackets, and long and short sleeve T-shirts. The designs weren’t just functional, they were distinctive, with reflective 3MReflective branding helping visibility in low light.

3M partnered with Sange Sherpa, a globally-know competitive trail runner, who trekked more than 10 days to get to the starting point of the race at Everest Base Camp. Racing in 3M equipped gear, Sherpa’s deep knowledge of the mountain, combined with the advanced thermal regulation and durability of his apparel, contributed to a top finish.
