CLIF Bar is going global in marathon running ahead of the 2026 season, adding new partnerships with the TCS London Marathon and BMW Berlin Marathon.
Sports nutrition brand CLIF Bar is expanding its presence across major international races, announcing new partnerships with the TCS London Marathon and the BMW Berlin Marathon ahead of the 2026 season.
The company has already worked with the Boston Athletic Association for several years, supplying runners at the Boston Marathon.
With the new agreements, CLIF will now be present at three of the six Abbott World Marathon Majors: Boston, London, and Berlin.
The brand says the partnerships are designed to support runners of all levels, from elite athletes competing for podium finishes to first-time marathon participants.
During race weekends in all three cities, CLIF plans to organize product sampling, merchandise stands, and re-fuelling stations along the course.
As part of the campaign, the company is launching a Strava initiative called the “Run the World Challenge”
The challenge will run from March 16 to April 26, leading up to the Boston Marathon on April 20 and the London Marathon on April 26. The Berlin Marathon will take place later in the year on September 20.
Participants who complete the challenge will unlock rewards through the platform. CLIF has also launched a sweepstakes offering running or cycling trips to destinations including Australia, Argentina, and Japan.
To mark the expansion, the company is releasing a limited-edition Chocolate Berry energy bar.
The bar is made with rolled oats and contains around 9 to 11 grams of plant-based protein, designed to provide steady energy during long-distance running.
