Rules & Regulations


The course will start from Chipping Street Car Park along  Cirencester  Road, turning right at the Royal Oak via the sharp ‘hairpin’ down towards the Millennium Green and the finish line. There will be a 10 foot ‘push zone’ at the start of the course – a 10 second penalty will be attracted if this zone is not adhered to by those assisting the start. 

It should be noted the course is quite steep, and in places participants can expect to reach 20-30 mph. Soapboxes will have one timed practice run to determine placing. These will be at single intervals. During the race, each competitor will be required to complete two timed runs; the average time of the two runs will be accepted as the finish time.


No expressed or implied warranty of safety shall result from publication of or compliance with this specification. This specification is not a guarantee against injury or death to any participant, spectator or official.

Event organisers shall be allowed to impose any further restrictions and to permit deviations from any of these specifications. Any deviations from this specification are left to the discretion of the event organisers. No expressed or implied warranty of safety shall result from any such deviation from this specification.

General Conditions

Every team must accept these Rules and Regulations in full. Any contravention of the Rules and Regulations may lead to disqualification and/or penalties.

Only two of the maximum six team members are permitted to be drivers on the race day.  The purpose of the practice run is to enable the drivers to get the feel of the course and their soapbox. The run will not count in the timed competition but will contribute to race order.

Registration and Scrutineering will take place from 8 am on race day, followed by practice from 10.30 until 12.00. Racing will commence at 12.00 until approximately 14.00 depending on weather etc.

Each team will get two timed runs, the fastest of which will be recorded as their official time. 

The Organiser’s reserve the right to refuse entry to any team without explanation. Their decision will be final.

Soapboxes and drivers will be scrutinised in the pits, (Chipping Car Park) prior to each run and at any other time, before being allowed to participate.

The Starter’s decision is final.

After crossing the finishing line drivers will need to apply their brakes and quickly depart from the track area, under the Marshal’s instructions.

There will be two categories of teams – ‘Juniors‘, composed of those aged 12 to 17 years old (inclusive) – and ‘Adults’, aged 18 and over.

The Organiser’s reserve the right to disqualify any or all participants that demonstrate inappropriate conduct.

For speed-related prizes, the fastest of the two runs will decide the winner.

Brightly coloured soap boxes, sponsorship and advertising are encouraged, with character and bodywork. “Naked” soapboxes consisting of chassis only will not be allowed. We would also appreciate the team name being painted onto the soapbox. For the safety of drivers and spectators, converted ride-on mowers and “quad” type vehicles will not be allowed to compete.
