Mammoth Trailfest. Announces Multi-Year Partnership With Craft Sportswear
Following a landmark 2024 event that drew nearly 2,000 runners from 22 countries and 40 states—with 47% female participation—mammoth trailfest. has entered into a new multi-year partnership with Craft Sportswear. This collaboration signals an exciting new chapter for the celebrated trail running festival.
Tim Tollefson, head crafter and founder of mammoth trailfest., reflected on the journey leading up to this partnership. “After losing our title sponsor, it was difficult to be honest,” Tollefson shared. “While we measure success in smiles and the feedback we get from our community, it’s hard not to feel disheartened when a sponsor moves on. But just like the seasons in the Eastern Sierra, change came quickly, and we soon found ourselves in discussions with leading brands in the running industry.”
Tollefson noted the importance of aligning with a partner that shared the festival’s core values. “We believe trail running has the power to change lives and improve communities,” he said. “At trailfest., we pride ourselves on being more than just a world-class event. The focus on experiences with movies, talks, parties, and kids events is our vehicle to reach people. We continue to push for more youth, women, and people from historically underrepresented communities to have access to this sport and it was important for us to find a partner that would help drive that mission forward.”
Enter Craft Sportswear, the Swedish brand renowned for its commitment to innovation and excellence in endurance sports. “Much like the upstart underdog we are at trailfest., Craft struck me as a brand ready to make noise,” Tollefson explained. “trailfest. celebrates every runner, from course record breakers to those who persevere to finish against the odds, and Craft is a community-driven brand that aims to inspire and enable athletic progress for world champions and everyday heroes. They made it clear they share the same vision and bring with them a 40 year brand committed to disruption.”
“Partnering with mammoth trailfest. and collaborating with Tim, a true icon in trail running, is an incredible opportunity for Craft,” said Niklas Moberg, Head of Brand at Craft Sportswear. “Trailfest. represents all that is great about the running community—celebrating the joy of running in nature and bringing people together on the trail. This partnership was a natural fit for us, and we’re excited to work even closer with Tim and help elevate trailfest. to new heights while creating a memorable experience for all participants.”
Looking ahead to the 2025 event, Tollefson shared his vision. “Everything we do at trailfest. is checked with, ‘Will this be best for our runners?’ In this new partnership with Craft, we will elevate the trailfest. experience for everyone involved, push industry boundaries in the event space, and launch initiatives to welcome more people into the sport, including an innovative program this summer in Mammoth directed towards high school kids and collegiate running programs.”
From oldtimers and newbies to course record breakers and cutoff chasers, trailfest. is a celebration of community focused on stewardship and storytelling. The 2025 event will take place September 18-21 in Mammoth Lakes, CA. Registration is now open for all events.
