The Trial GB series is the official ACU British Motorcycle Trials Championship since 1950. It is the oldest domestic national level trials competiton in the world, and the producer of some of the sports finest athletes.

A Trial is a test of riding skill and balance over a variety of observed obstacles with riders incuring penalties for footing or for failing to fulfil other conditions. Trials events require the competitor to complete individually observed zones, known as sections. There is a time limit of one minute and thirty seconds per section, in addition to a time limit to complete the entire course. The participants journey through each section who is judged by an ‘observer’ who records a score. These scores are totalled across all 36 sections and the rider with the lowest score will win the day. It is very similar to golf. It is the rider vs the course.

Trials is famed for the athletes extreme finesse and fine control of the motorcycle. In no other motorsport will you witness such balance, determination and commitment from the riders to complete the course, and in no other motorsport will you be able to get so close to the action!
