Sedgefield has become the latest casualty of the cold snap with Tuesday's meeting abandoned due to a frozen track and snow.
Clerk of the course Phil Tuck had called an inspection for 12.30pm but he brought forward that check after another cold night.
He said: "We brought forward the inspection as there's no prospect of a thaw. We fell below freezing again last night and are forecast minus temperatures again tonight, so there's no chance of us racing and we have abandoned."
