London Marathon Events has announced CLIF Bar as the Official Energy Bar Partner of the TCS London Marathon.
This collaboration unites two organisations committed to supporting (and fuelling) every participant – from the seasoned athlete to the brave first-timer – across the Finish Line.
The partnership will cover the next three editions of the TCS London Marathon, from 2026 to 2028.
CLIF Bar, renowned for its delicious mix of whole oats and plant-based protein is crafted to enable participants to enjoy, not just endure, the long miles. To support every participant on their journey, CLIF Bar will be present at the 2026 TCS London Marathon Running Show between Wednesday 22 and Saturday 25 April, offering samples to all participants as they prepare for Event Day.
Bianca Harvey, CLIF Director Europe, Mondelez said: "The TCS London Marathon is an iconic event that truly embodies the spirit of being in it together, and we are incredibly proud to join as the Official Energy Bar Partner. CLIF Bar provides purposeful, plant-based energy, empowering every participant, from the first-timer to seasoned athlete, to perform their best and experience the joy of the Finish Line. Our commitment mirrors the TCS London Marathon's ethos of inspiring and supporting every single participant on their incredible journey, from training to Event Day."
Hugh Brasher, CEO of London Marathon Events, said: “Getting your fuelling right is a crucial ingredient for all TCS London Marathon participants during training and on Event Day, so we are delighted to welcome CLIF Bar as the Official Energy Bar Partner of the TCS London Marathon.”
The 2026 TCS London Marathon takes place on Sunday 26 April.
