The aim is to raise as much as possible for Cool Earth, the London Air Ambulance, and the British Red Cross.

London Air Ambulance works alongside the London Ambulance Service to bring a rapid medical response to more than 10 million people, and they need £6 million to acquire a second helicopter. The Air Ambulance has treated over 32,000 people since its foundation. Check out their website here: http://londonsairambulance.co.uk/

Once under way, you will be able to keep track of us with the rally blogging site - more on this later. Thanks in advance for your donation, and wish us luck!
