CLIF Energy Bars Named Official Sponsor for 2026 Boston Marathon

The performance nutrition brand CLIF has now become the official energy bar for three Abbott World Marathon Majors: the 2026 Boston Marathon presented by Bank of America, the TCS London Marathon, and the BMW Berlin Marathon.

According to the nutrition brand, the expanded sponsorships are focused on supporting athletes from elite runners to first-time marathon participants.

An Endurance.BIZ report noted that, as part of its sponsorships, CLIF will host event-weekend activations that include product sampling, merchandise pop-ups, and refueling stations for runners and spectators.

CLIF has also announced that, from March 16 to April 26, it will launch a new "Run the World Challenge" on Strava. This activation will allow race participants to unlock rewards and celebrate the lead-up to the Boston, London, and Berlin races.

According to the company's news announcement, the "Run the World" campaign will also include the release of a limited-edition CLIF Chocolate Berry energy bar. A sweepstakes has also kicked off at the beginning of the month, allowing participants to win a running or cycling trip to international locales such as Australia, Argentina, or Japan.

The 2026 Abbott World Marathon Majors season begins with the Boston Marathon scheduled for April 20, followed by the London Marathon on April 26. The Berlin Marathon, organized by SCC Events, will be held on Sept. 20.
