When I was travelling around the world without flying, I was shocked in San Salvador to see young children sleeping on the pavement outside a shopping mall. Since then I've been supporting Toybox, a British charity that works with such children, protecting them from the dangers of the street and helping them to get an education. I have visited the HQ of Toybox in Bletchley and was impressed by the team.  I've never taken part in a sponsored event before, but this is something I must do.

JustGiving is approved by Toybox and hundreds of other charities. It enables you to sponsor me simply, swiftly and safely. Once you donate, they’ll send your money directly to the charity. So it’s the most efficient way to donate – saving time and cutting costs for the charity.

Please give whatever you can afford. Whether you know me as John or Philip, thank you very much for supporting this, my latest and most worthwhile adventure.
