Craft Sportswear Named Title Sponsor of The Mammoth, a 210-Mile Footrace Through California’s Eastern Sierra

July 10, 2025

MAMMOTH LAKES, Calif. (July 10, 2025) /ENDURANCE SPORTSWIRE/ – Craft Sportswear, the Swedish performance brand known for its technical innovation in endurance apparel and footwear, has been named the title sponsor of The Mammoth, a new 210-mile ultra-endurance race taking place September 26–30, 2025. This multi-year partnership builds on Craft’s existing relationship with Mammoth Trailfest and reflects the brand’s commitment to community, access, and supporting trail runners at every level.

The Mammoth offers a bold new challenge in one of North America’s most awe-inspiring landscapes. Beginning and ending in Mammoth Lakes, California, the route circumnavigates a 760,000-year-old supervolcano caldera and covers a stunning range of Eastern Sierra terrain.

Created in response to growing interest from runners seeking longer, more immersive trail experiences, The Mammoth is a natural extension of the Mammoth Trailfest’s mission to build from the community, for the community. The race already boasts participants from 20 states and six countries, with women representing more than 30 percent of the field, the highest of any 200-mile race in the country.

“At Trailfest, we pride ourselves on celebrating everyone from cutoff chasers to course record breakers, and Craft has continued to demonstrate this shared ethos,” said Tim Tollefson, head crafter and founder of Mammoth Trailfest and The Mammoth. “Craft is committed to elevating the voices of runners from the front of the pack to the very back, and we are excited to deepen this ongoing relationship with the brand to build an event unlike anything else.”

The course was designed to highlight the Eastern Sierra’s rich biodiversity and dramatic terrain. Runners will pass through high alpine forests, sun-soaked valleys, and remote mountain trails, with two summits of Mammoth Mountain at 11,053 feet offering panoramic views of the surrounding region. Every stretch of the route reflects the natural beauty and untamed spirit of the landscape.

Craft shares in the event’s vision of creating inclusive, community-driven experiences and amplifying important stories within the trail running space.
“We’re very proud and happy to deepen our collaboration with Tim and Trailfest. Craft has been an endurance brand at its core since the mid-1970s, so supporting Tim in elevating the Mammoth felt like a natural fit,” said Niklas Moberg, head of brand at Craft.

Craft’s trail footwear is uniquely suited for The Mammoth’s varied and rugged terrain. From alpine ridgelines and volcanic domes to village footpaths and backcountry routes, the brand’s shoes are built to handle the demands of this remote and runnable course. The event will also serve as an ideal proving ground for Craft’s new FW25 gravel footwear styles, which will be on display throughout race weekend as a perfect match for the diverse terrain athletes will encounter
