This year’s 60-mile London to Brighton run from Hyde Park to Madeira Drive will now include a regularity trial on 3 November.
Competitors can choose a specific time to aim for: three hours equates to a 20mph average speed, but with the choice of one-hour increments up to six hours at an average speed of 10mph.
For each minute under the target time, two penalty points will be imposed with one point imposed for each minute over the nominated time. Winners will be the cars with the fewest penalty points in each of the four time classes.
Ben Cussons, Chairman of the Royal Automobile Club, said: “The Steering Group is committed to evolving the event and adding value and involvement for the participants. We are restricting the Trial to 150 entries for the first year as it is a new initiative.”
