A grand total of £100,000 has been raised for the Thames Valley Air Ambulance through 10 years of the Gravity Grand Prix.
The annual event organised by the Kaffirs of Cookham Dean has been supporting the charity since its first race day in 2006. The latest event on Sunday saw the total hit the six-figure mark.
The 2016 event raised £15,000 for the charity, raised from entry fees, racers' sponsorship and donations being made on the day.
Peter Austin, race controller and treasurer of the Kaffirs, said: "It is a very worthwhile cause to support and to average £10,000 raised each year isn't bad going.
"We've just been so lucky with the weather each year to bring people out. Now it's really quite a big event, in the first year we had no idea it would be quite that big but in the last few years it has grown."
The air ambulance also provides volunteers to help marshal the day as well as provide first aid assistance if needed.
The Kaffirs, who also organise the annual Boxing Day Games, will continue to support the Thames Valley Air Ambulance with future Gravity Grand Prix races.
Peter added: "It's a very worthy cause and the air ambulance provides us with lots of volunteers on the day."
As the event has grown, the Kaffirs have found it hard to gain the volunteers needed to ensure it can run smoothly and safely.
Peter encouraged anyone who would like to help out on the day, or ahead of it, to call him on 01628 482201.
