The Gravity Grand Prix is intended to be a free family fun day for the benefit of local residents. It is held at the end of the summer so that it gives families and individuals a project throughout the long summer months.
The popularity and fun of the event means that it’s a great platform to raise money for good causes. This year, once again, we have a target of £1,5000 (we’ve already raised over £150,000 during the previous years)! And remember it’s all done for charity. All of us involved in running it are volunteers.
You can help to reach this target in three easy ways:
We ask that each team set themselves a minimum target for sponsorship, Although this is not a condition of entry.
You will be sent a sponsorship form when your entry application is accepted and extra copies can be downloaded from this website. Some teams have raised as much as £2,000.
Find a kart sponsor – Get a company to sponsor your kart. As previously described, entering a kart can be a good team building exercise.
Rules and Regulations 2021
These Rules and Regulations apply to all entries; they have been designed for your safety and the safety of others around you. They enable us to run the event effectively for the maximum benefit of all, so please ensure that you read them carefully and comply with the details.
If you have any comments or concerns please contact Simon Greenlees email@example.com
The course will be from the junction of Church Road and Spring Lane to Uncle Tom’s Cabin, with a length of 750m and a drop of 30m. Some karts can expect to reach speeds of 30-40 mph. There is a very sharp S bend, Widowmaker's bend, followed by a steep gradient shortly before the finish. As in previous years, there will be a chicane after Widowmaker's to slow the karts before the finish. In recent years we introduced a second chicane before the Dunlop arch. We will do the same again this year. A chance to display your driving skills and thrill the crowd. Your kart must be robust enough to get through these obstacles.
Your kart MUST HAVE EFFICIENT BRAKES and excessive ballast must not be carried. As the design and weight of karts will be highly variable, what is deemed as excessive ballast will be determined by our scrutineer, Simon Greenlees. You must therefore agree with Simon the amount of ballast allowable for your kart before the final build is submitted for scrutineering and he must be satisfied that he can lift either the front or back edge of your kart without exceptional effort. Simon Greenlees’s decision will be final. No additional ballast may be added after scrutineering or on race day itself. This can result at you being prevent from racing.
Every team must read and accept the Rules in full. Applications must be made using the entry form.
A team will consist of a maximum of four persons; up to three in the kart and one pusher.
Pushing, by up to two team members, will be allowed from the start to a line approximately 50m from the start. Any infringement will preclude the team from the fastest time awards.
Participants must be over the age of thirteen, with the driver being at least sixteen. All participants under the age of sixteen must have the permission of their parents to take part and a parent must sign the Indemnity Form for them on the day of the race.
Each team should finish their karts at least two weeks before the event to allow for scrutineering.
The Organisers reserve the right to refuse entry by any team, at any time, and for any reason.
No head first driving.
Karts will be towed up the course in groups and must be fitted with strong eyelets front and back to accept the towropes provided by the race Organisers. Karts must be strong enough to tow up to ten other karts behind. If this later point is a concern please discuss with Simon Greenlees and the Towing Team on the day.
Numbers provided at registration must be prominently displayed on the front of each kart.
Teams with a good idea for a fun kart may apply for exemptions to the rules and the design criteria.
The officials’ time is final, even if it’s incorrect.
There will be two runs down the course, with a run-off, at the Organisers' discretion, for the fastest karts.
Run One: The first timed run which is also an opportunity to show off the karts.
Run Two: The second timed run.
Run Three: If applicable and only the fastest karts
After the Gravity Grand Prix all entrants will be towed to the prize giving on the Old Cricket Common.
Technical Design Criteria
All karts must be constructed with pedestrian and spectator safety in mind. Sharp edges will not be permitted.
No glass or other materials that could shatter or cause injuries to drivers, passengers or spectators in the event of a crash may be used in the construction of the kart.
Maximum width 1.2m measured from outside to outside.
No protuberances outside these dimensions will be allowed.
Once seated, drivers must be forward facing and along with the passengers remain seated throughout the race.
Karts must have a minimum of three wheels. All wheels should be in road contact during normal running and must be spaced to give the kart stability from side to side, i.e. they must not be in a single line as on a bike or motor bike.
The wheels must either be solid or if they have spokes, they should not allow a tennis ball to pass through the spokes. Bicycle wheels are acceptable. If a tennis ball can pass through the spokes the wheels must be covered.
Good brakes are essential and will be checked. Wheel braking must operate on at least two wheels on the same axle and be effective. The brakes must operate on the wheels and not damage the road surface.
Seats must be securely bolted to the kart.
Karts must be designed to carry no more than three persons, in a feet first direction.
Any steering column, brake lever or other protrusion must be designed and fitted such that the risk of injuries is minimised.
Bodywork and controls must not impede the driver/passengers in exiting the vehicle unaided.
Any doors or hatches required for access must be readily operated from both inside and outside the vehicle without the use of tools.
Steering must not have excessive free play or any characteristic tending to promote instability.
Gravity propulsion only – i.e. no motors, no pedals, no stored potential energy nor excessive ballast.
Seat belts are not mandatory, but if seat belts are used they must be of a minimum four point fixing and only on karts with a roll-bar.
It is recommended that drivers and passengers should wear a safety helmet and appropriate gloves. Clothing must be capable of withstanding a spill on tarmac or concrete. No bare limbs please.
All karts should be available for scrutineering two weeks prior to the event. The location for scrutineering karts will be notified to team leaders in good time before the event. Karts deemed not safe at the start of the race will not be allowed to race.
Important - Safety Info and Conduct on the Day
The purpose of the event is to have fun, but the safety of the team, supporters and spectators is paramount throughout the day and, accordingly, the organisers reserve the right to amend these rules or go above and beyond their guidance. With this in mind if in the opinion of the race officials, a competitor’s ability to be safely in control has been compromised by alcohol, drugs, illness, injury, or emotional stress, that competitor will not be allowed to continue the event.

Only team leaders wearing wrist bands will have their teams allowed on the course or the karts during any part of the event. It is the responsibility of the team leader to ensure all drivers and riders are familiar with the rules & regulations.
After crossing the finishing line drivers will need to apply their brakes and quickly depart from the track under the Marshal’s instructions. An uphill towing service will tow the karts up hill. Please make sure that your kart is strong enough to tow 10 other karts. If this is a concern please discuss with Simon Greenlees during scrutineering and the Towing Team when you finish your run
