Riders can choose to cover any distance from 200 to 540 miles in the allocated 20 hours, and can start at one of the five major control points from 2pm on Saturday and visit as many of the controls within the 540-mile maximum as they can to finish by 10am on Sunday.
A navigational scatter allows bikers to devise their own routes from a supplied matrix listing of more than 50 controls located in England.
There are a range of prizes to be won for the riders who get to the most controls and therefore clock up the most miles, and all finishers achieving their target receive a plaque.
This year’s major controls are located at Frome, Leeds, London, Whitchurch and Wisbech.
The rally is organised and managed by a team of volunteers who make up the ACU Rally Committee and in conjunction with the British Motorcycle Federation (BMF) help raise money for the learning disability charity Mencap.
The rally was first run in 1933 (there have been gaps) but is still the longest running and largest motor sport event run on the public highway in the UK, attracting well over 500 entries every year.Click here to subscribe.
