Covering the 2026, 2027, and 2028 editions of the iconic race, this partnership focuses on providing high-quality, plant-based fueling options for the tens of thousands of participants tackling the 26.2-mile course.
The collaboration will kick off at the TCS London Marathon Running Show, held between April 22nd and 25th, 2026. During the event, CLIF Bar will be prominently featured, offering samples to runners as they collect their race numbers and finalize their training preparations.
