Yes this is OFF ROAD TRIALS, very much the same principle as a motorcycle trial. Some events using road miles linking observed sections, others are single venue. Some events are combined with motorcycles & sidecars. The sections are graded (distance climbed) for cars and standard 0,1,2,3,5 for bikes.
The above wasn't really where I was heading...It was more that the VSCC have locked down the machine eligibility side of things using a logbook system and it hasn't reduced entry numbers.
I'm on the fence either way was just throwing out some ideas as as youngster hoping to see the Pre 65 scene keeps going.
