Please contact us if you are interested in joining Team SOS and raising funds for our work. There are hundreds of challenge events you can sign up for in the UK and all over the world, or we can help you come up with your own unique fundraising plan.

We can offer support in the form of inspiration, information materials, collecting tins, helping you obtain permits for public collections, and more.

Hannah & Lucy organised their fundraising together, trained together and ran together. Between them, they managed to raise just over £3,200. This is the equivalent of planting 800 new trees to restore forest habitat for orangutans in an area which had been slashed and burnt for palm oil plantations. Would you like to challenge yourself?
