Charities
This event is jointly organised by Over The Wall Camp Children’s Charity, Action Medical Research, and Liberty (our generous Lead Sponsor). The event is also directly benefitting The Brain Tumour Charity. Participants can choose to support whichever of the four charities most resonates with their charitable focus, safe in the knowledge that every penny raised will support their chosen cause – with all event costs covered by Liberty.
We also partner with GivenGain, the not-for-profit fundraising platform that ensures 100% of donations go to charity. You’ll get the chance to automatically create your fundraising page when registering for the event.
If this unique urban challenge appeals to you, why not recruit a team of like-minded friends or colleagues and sign up collectively. You can spur each other on when times get tough. All participants can bring up to three spectators to join them at the finishers’ reception, giving you the ultimate base for a London family day out after.

Over The Wall Camp
Owing to long-term health conditions, more than 1 in 10 children in the UK can be denied a carefree childhood, and this number is growing. Over The Wall Camp is a UK based charity for children and young people with health challenges and disabilities to discover a world of mischief and magic. We provide a safe place to step outside of comfort zones, establish friendships and build confidence through meaningful and exciting activities. These amazing experiences are in-person at residential camp, and also available online with Camp in the Cloud. And what’s more, it’s all free!

Action Medical Research
Action Medical Research is the leading UK-wide charity dedicated to funding vital research to help sick and disabled babies and children. We have been funding medical breakthroughs since we began in 1952 and almost everyone has been touched in some way by our groundbreaking work like the first UK polio vaccines, ultrasound in pregnancy and the rubella vaccine. The research we have funded has helped save thousands of children’s lives and changed many more.

Committed to saving and improving lives, we fund world-class research across the global eco-system of experts to find cures and better treatments. We offer the highest level of wrap-around care and support with clinics for children and young families, welfare, benefits and mental health as well as driving urgent change by raising awareness and campaigning for more national support.

Through your donation, we are able to provide the care, support and treatment pathways that would otherwise never be available to them.
