March 31, 2026

BOULDER, Colo. (March 31, 2026) /OUTDOOR SPORTSWIRE/ – Mammut, the Swiss mountain gear pioneer with more than 160 years of experience in alpine innovation, is partnering with the premier high-altitude trail running series, the Cirque Series, as its official apparel sponsor for 2026. Known for its steep, leg-burning courses and festive après-race atmosphere, the Cirque Series will host ten races across the U.S. this summer.

Drawing runners from all levels of experience – from world-class athletes to passionate mountain enthusiasts – the Cirque Series features races ranging from eight to ten miles, each gaining between 3,000 and 4,000 vertical feet. The 2026 tour includes iconic mountain destinations from Vermont’s Killington Resort and Colorado’s Arapahoe Basin to Alaska’s Alyeska and California’s Mt. Baldy. Each event celebrates the heart of mountain culture, bringing together the communities and athletes who live for high-altitude adventures.

As part of the sponsorship, Cirque staff and volunteers will be outfitted in Mammut’s performance trail running apparel. Mammut will also host vendor village activations, gift custom race swag to participants, and provide podium prizes for top finishers. The partnership highlights Mammut’s ongoing commitment to developing performance gear that empowers athletes to explore farther and move with confidence in the mountains.

“Mammut stands at the pinnacle of outdoor brands,” said Cirque Series founder Julian Carr. “Showcasing Mammut as our official apparel sponsor strengthens our mission to deliver the best running experiences possible. The quality and performance of Mammut gear empowers our athletes to push their limits across the demanding terrain our races are known for. We’re thrilled to partner with a brand that shares our passion for celebrating mountain sport.”

The collaboration aligns with the launch of Mammut’s all-new Spring 2026 Aenergy Trail Running Collection, a purpose-built line of trail running gear engineered for mountain adventures. Highlights include:

• Aenergy TR HS Hooded Jacket: The lightest, most packable 3-layer hardshell Mammut has ever built – crafted for full waterproof protection and next-level breathability on fast-paced alpine missions.
• Aenergy Trail WB Hooded Jacket: Take the edge off the windchill in this lightweight and technical windbreaker. The perfect backup for your mountain missions, it packs durability, breathability and comfort into a conveniently tiny package.
• Aenergy Trail Accessories: Including the Aenergy Trail Vest 12, Trail Belt, and Ultra Carbon Poles, each piece is built for comfort, balance, and performance when moving fast through technical mountain terrain.

“The Cirque Series perfectly captures the spirit of mountain performance,” said Matt Kaplan, Managing Director of Mammut North America. “It’s the ideal stage to unveil our new Aenergy Trail Running Collection, designed for athletes who demand reliability, speed, and performance from peak to valley. The collection and partnership with Cirque further reinforces our position as a high performance four season brand.”
