lululemon doubles down on its commitment to the run community and becomes Title Sponsor of Boulderthon

April 22, 2026

BOULDER, Colo. (April 22, 206) /ENDURANCE SPORTSWIRE/ — Boulderthon has announced lululemon as its new multi-year title sponsor, which will bring the event to new heights, featuring exclusive lululemon apparel for all finishers, as well as the return of the pre- and post-race lululemon VIP Experience. Registration for Boulderthon, presented by lululemon taking place this year on Sept. 27, is now open. Spots are expected to fill up fast, with last year’s event selling out months ahead of race weekend.

“lululemon stepping in as this year’s Title Sponsor helps steward Boulderthon into its next chapter. As a nonprofit, community-driven organization, we sought a partner whose long-standing investment in Colorado truly reflects the values at the heart of our event,” said Alexa Squillaro, event director of Boulderthon. “lululemon embodies those values – community, performance and a deep commitment to the places where athletes live, train and belong. This partnership allows us to elevate the participant experience while creating meaningful, lasting value for the broader community.”

All race participants of the 2026 Boulderthon presented by lululemon will experience new race day elements thanks to the retailer’s commitment to high quality and performance. One of these features includes custom Boulderthon premium lululemon running apparel. Registrants will get to choose between a lululemon Metal Vent Tech long sleeve or Swiftly Tech hip length long sleeve. As part of the full race experience, a premium lululemon x Boulderthon merchandise shop and product lineup will be onsite, powered by the Fleet Feet shop on Boulderthon Race Weekend.

“For runners, Colorado is a dream destination to experience some of the most beautiful trails and is where Olympians will often train before competing on the world stage,” said Kara Schlosser, Vice President, North America Community at lululemon. “Connecting with the run community is an essential part of who we are, and our guests not only feel that through our products but also in the partnerships we forge and how we show up in every community where we have our stores. We are thrilled to be Boulderthon’s title sponsor and to engage with this year’s participants from the pre-race to the finish line and beyond.”

The lululemon VIP Experience has historically sold out and is trending towards another sell out for the 2026 event with 350 expected participants, and takes place throughout race day, beginning at the start line with a heated VIP lounge filled with snacks, comfy seating, and no-wait restrooms.

On top of providing pre- and post-race lululemon VIP Experiences, lululemon will also serve as the presenting sponsor of the Final Finisher Program, which recognizes the final 40 participants who cross the finish line, providing an energetic atmosphere as well as gift bags to celebrate their accomplishments.

Boulderthon and lululemon began their partnership ahead of the 2024 Boulderthon where they launched their “VIP Lounge”. The exclusive lululemon VIP Experience continues to be a success for both parties, leading to the continuation and expansion of the partnership.
