Distance: 25/50/100KM | Registration Fee and Fundraising Target: variable

England’s greatest river provides a fantastic backdrop for an unforgettable challenge. Over 3000 adventurers will join the Putney Bridge start, and the full 100km route heads upstream to Henley along the famous Towpath. It’s through Richmond, Hampton Court, Runnymede, and Windsor, with some wonderful scenery to a riverside finish line. There are 50km & 25km distance options also available – plus the separate 25km ‘Thames Bridges Trek’ & ‘The Moonlight 10 Walk’ through Central London as part of the weekend. 

Why Child Bereavement UK?

Child Bereavement UK helps families to rebuild their lives when a child grieves or when a child dies. We support children and young people (up to the age of 25) when someone important to them has died or is not expected to live, and parents and the wider family when a baby or child of any age dies or is dying. We provide training to professionals in health and social care, education, and the voluntary and corporate sectors, equipping them to provide the best possible care to bereaved families.
