Donations for our golf marathon

We are a group of four boys from Surrey, Matthew Slominski- Jack Doyle- Oliver Cronk- Will Wieland, who are trying to raise money for a brilliant charity called Challenge Aid https://www.challengeaid.org. Challenge Aid build schools in some of the poorest and most deprived communities around the world. We hope to raise money for them by completing a golfing marathon at Burhill golf course. This marathon will consist of dawn to dusk play, aiming to fit in as many holes as possible. We are  planning to play 4 rounds at the moment. Any contributions would be really appreciated. Challenge Aid is a great charity with a great cause and We hope to raise as much money as possible. Thank you!
