About us

Welcome to The Big Half 2025 team for Become!

Many amazing people from the Become community are running The Big Half on 7 September 2025 to help fund our services for care-experienced young people and campaigns for a better care system.

This 13.1-mile challenge in London is for everyone, whether you're a seasoned runner or just starting out. Join the biggest team Become has ever brought together, feel the benefits of running, and make a difference for care-experienced young people.

“Since I was in care at a young age, Become has always been the pioneering charity supporting young people in care and care leavers.”

- Sahil, Become runner

Every pound raised helps to ensure there’s someone at the end of the phone when a young person calls for help and that the voices of care-experienced young people are amplified to bring about the change they want to see in and around the care system.
