The wheels are in motion for the 88th staging of the Wild and Woolly Boxing Day scramble.
The event is held at Arm Farm in Blisworth, and raises money for the Warwickshire and Northamptonshire Air Ambulance, Help for Heroes and a number of Blisworth causes.
Last year’s event attracted a record crowd, raising £3,277 in the process, and the organisers are hoping this year will be even better.
Northampton Motorcyclists’ Club chairman, Fraser Law, said: “We have a full line-up of 50 bikes this year. It is going to be brilliant, one of the best Woolys for a long time.
“We have changed the track around quite a bit, to make it better for the spectators. We have moved the start and finish areas so it is nearer to the spectators.
“The weather was pretty extreme last year, and this year it looks like it will be a lot milder. The whole of December was terrible last year.
“It will be a lot easier underfoot, and we are expecting it to be a better race.”
The event is the world’s oldest race which is still running.
The capacity field will race to complete the most laps of the one-and-a-half mile course in one hour.
Practice gets under way at 10am with racing from 11am.
