Join us for fundraising events – from walks to marathons and more

Whether it's running a half marathon, climbing the steps of the Walkie Talkie, or enjoying one of our seasonal celebrations, take part in a fundraising event and help give seriously ill children the best chance and the best childhood possible.

For the hundreds of children from all over the UK who are treated by Great Ormond Street Hospital every day, for children with rare or complex illnesses everywhere, for this generation and all those to come.

Be part of it.
