MCC events cater for a range of vehicles and classes and are operated within professional sporting guidelines.

Our events are run in accordance with the Standing Supplementary Regulations (SSRs.) Each event also has its own Additional Supplementary Regulations (ASRs).

Our rules and regulations are quite long, but don't let that put you off. Once you understand how your class operates it's fairly straight forwards.

If in doubt ask. You can ask questions via our Facebook Group or the contact page. At an event, if you’re unsure of anything ask an official or fellow competitor. Everyone is very friendly.

Here's a quick guide:

1: Make sure that you have entered the event in the correct class for your vehicle.
2: Read and comply with the ASRs for the event.
3: Make sure your vehicle has the correct tyres. There is a list of permitted tyres in section 4 of the SSRs.
4: The rules for motorcycle tyres are defined in the SSRs with additional rules here.
5: Make sure that your vehicle is fully road legal.
6: Follow the instructions in the event route book, available online to each entrant some time before the event starts.
7: Comply with the instructions of club officials.

Vehicle Classes

Cars must be two-wheel drive, non-commercial and fitted with road tyres from a prescribed list. Most motorcycles and sidecars are required to be fitted with trials tyres front and rear, though there are exceptions to this for certain classes.

Good vehicle choices are hotly debated by club members – some will recommend the thrill of bouncing up slippery hills using horsepower whilst others will advocate lightweight vehicles with superior tractability and manoeuvrability. Increased ground clearance and protection for exposed parts are popular modifications for competitors driving our classic trial sections.

Vehicle classes are intended to serve as a handicap system for drivers and riders of vehicles deemed to have an advantage over a typical road going vehicle. Drivers of front-wheel powered cars can expect no handicap, whilst drivers of rear-wheel drive ‘trials special’ cars with rear-mounted engines can expect to compete under the full weight of class eight.

Exceptionally, and at the Club’s discretion, historically interesting or traditional trials cars, or other cars which have a recognised disadvantage or advantage in their defined class, may be reclassified. On the basis of their performance, or potential performance cars may be placed in a nominated higher or lower class. Competitors wishing to make use of this discretion must apply to the General Secretary with the full specification of their car and the justification for inclusion in a nominated Class. The Club will issue a Reclassification Certificate to accepted cars which will be valid for one or two years in the first instance and be renewable at 2 yearly intervals thereafter. Conditions may be attached to the certificate.

To celebrate the Exeter Trial’s 90th anniversary the MCC organised a separate ‘Run’ which took place alongside the actual trial but used only hills of a totally non damaging character. These had figured in past trials but by their nature were no longer difficult enough to be of interest to present day competitors. This event-within-an-event was an immediate success with competitors asking for more of the same and from this was born our present Class O.

This is an entirely separate class in each of the three MCC classics. It is part of the main trial using a similar route but deviating to take in easier hills, usually with a historic MCC background, and a shorter night road section. Unlike the regular classes with gold, silver and bronze medals, plus class and overall awards, there are no prizes here other than for finishing without penalty which means that no competitor’s success or failure can affect another. This takes us back to the basis of all MCC trials which is for the competitor to be pitting his skills against the club.

Anyone in any type of car or motorcycle can take part in Class O and consequently it appeals to many for whom the general classes might be too competitive. These competitors may be people who are newcomers wishing to dip their toes into the water before tackling the real thing or “Oldies” who still enjoy being part of an MCC event but for whom age or health presents a problem. The class also appeals to owners of old, interesting but fragile, machinery which could not cope with the hurly burly of today’s sections but which would be perfectly at home with the less damaging hills of, say, fifty years ago. Competitors on two, three or four wheels all run together in true MCC manner, the club being one of the very few where drivers and riders rub shoulders.

It would be a mistake, though, to think that Class O is merely a nostalgic social run in interesting countryside. All the hills have a sting in them. Some are surfaced but have enough gradient and corners to make drivers think, particularly when faced with a restart on the most difficult bits. Those that have gravel or muddy surfaces, although not rough and damaging, are “stoppers” in their own right ensuring that vehicles should be carefully prepared and competently driven. To claim a Class O award for a faultless performance, which appropriately takes the form of an MCC medal cast from genuine Cornish tin processed from our own Blue Hills Mine, is no mean achievement.

The introduction of Class 0 has certainly added a new dimension to the three MCC Classics, allowing fifty or more members each time to sample the action rather than having to stay at home regretting their inability to compete due to age, lack of experience, or possession of suitable machinery.


Trial classes

We offer Classic Road Trial (Class R), which is proving increasingly popular as an introduction to MCC trials. R class offers an all tarmac challenge for both cars and motorcycles.

The following is a brief summary, please read the SSRs for a full description.

a) Any vehicle is eligible (subject to acceptance by the Clerk of the Course and complies with item d below). b) Run on a modified course of a less damaging nature. c) Vehicles and entrants must comply with the SSR. d) For practical reasons, the number of entries in this class may be limited.
Classic Road Trial (Class R)
This is proving increasingly popular as an introduction to MCC trials. R class offers an all tarmac challenge for both cars and motorcycles. a) A test of hill climbing ability, navigation, and timing. b) Run on a route with non-damaging surfaces, the majority on sealed surfaces. c) Open to any road legal motorcycle or two-wheel drive motor car, subject to the Clerk of the Course’s decision on eligibility/desirability of any vehicle. d) Fitted with road legal tyres. Tyres to be E marked and not marked for competition use only. e) Competitors will not be eligible for any Premier or Annual award. f) Motorcycles to comply with ACU regulations. g) Cars to comply with Motorsport UK regulations. h) With the exceptions of the above, vehicles and entrants must comply with the SSR.

The club uses a written roadbook method of navigation which usually necessitates a passenger (car drivers) or a roadbook holder (motorcyclists). GPS is welcome as an aide-memoire, but given that our routes vary from year-to-year (and power supplies can fail) this should not be relied upon as a primary method of navigation.

A typical instruction might read:

In 0.3 miles at X L DP Sutcombe. In 1.1 miles L at X DP Holsworthy (QQ).

Which translated, is understood to instruct:

In 0.3 miles at the cross-roads, turn left onto the road where a direction post reads ‘Sutcombe’. At the cross-roads in a further 1.1 miles, turn left onto the road where a direction post reads ‘Holsworthy’, and proceed very quietly.

Small (c.5-inch), square direction signs are used at some junctions in rural locations to assist with navigation. These will usually read ‘L’, R’, ‘SO’ or ‘QQ’ as required. Roadbooks are printed in A4 size and are made available to competitors up to two weeks before. They also contain important information concerning restarts, observed tests and essential final instructions required to keep competitors safe and organised.
