A record number of decorated tractors are set to take to the roads of south Norfolk at the weekend for the annual Ladies' Tractor Road Run.

Around 120 women will take part in the charity event on Sunday that will drive in convoy on a 20 mile circuit through Harleston and the surrounding villages.

The tractor run has raised �184,000 for Cancer Research UK since 2004 and organisers hope the eighth rally will break the �200,000 mark.

The convoy will depart Thorpe Abbotts Airfield at 11.30am on Sunday and will pass through Harleston at 12.30pm with a picnic lunch at Gawdy Hall meadow at 1pm. They will finish at the airfield at about 4.30pm.

The pink ladies' tractor run is organised by the Suffolk and Norfolk branch of the David Brown Tractor Club to raise breast cancer awareness and funds for cancer research.

Last year's event raised �34,000.

Annie Chapman, who coordinates the tractor rally with her husband John, said: 'We said that the cut off was 100 tractors, but it is hard to turn people away when they turn up with a tractor for charity.'
