London 25km Challenge

Push your limits as you pass world-famous landmarks and cross some of the city’s historic bridges

Join us for a challenging urban 25km walk through the capital, taking in its most iconic sites and bridges along the way. Every step you take will help support families with a seriously ill or dying child, keeping them close when it matters most.

Committed minimum sponsorship £200.

Minimum age 13. Children between the age of 13 and 16 must be accompanied by a participating adult. Well behaved dogs welcome on a short lead.
