The Gravity Grand Prix is Cookham Dean’s most exhilarating tradition - an annual downhill race where speed, creativity, and pure gravity collide in spectacular fashion! Since 2007, daredevil racers have strapped into homemade karts, braved the slopes, and entertained a cheering crowd of thrill-seekers in their thousands.

During 17 fantastic years, we've raised an incredible £250,000 for Thames Valley Air Ambulance and other local causes - all while having an absolute blast! This is more than just a race; it’s a full-on festival of fun, packed with laughter, adrenaline, and some of the wackiest, most ingenious karts you’ll ever see. Think rocket ships, castles, or even a rolling bathtub - every creation adds to the magic!

Last year's event on Sunday, 15th September 2024, was our 17th run, keeping the tradition alive (with just one break in 2020, thanks to Covid-19). Thinking about joining the madness in 2025? Stop thinking and start building! Check out the Information Pack page on this website to get started. The exhilaration of building your own kart is matched only by the adrenaline rush of speeding down the track, with the roar of the crowd echoing all around you.

In 2024, we had a bumper crowd basking in the September sun, enjoying the spectacle of flying karts and a whole lot more - scrumptious food stalls, our legendary beer and wine tent, pub fare along the course, and a funfair for the kids.
