Thursday's meeting at Fakenham has been abandoned due to snow.
Clerk of the course David Hunter inspected the track at noon on Tuesday but was forced to admit defeat.
Hunter said: "There's been a little movement on the snow, but we've still got three inches of snow on the course.
"The temperature peaked at minus 11C last night, much against the forecast, and we are only about 2C at the moment. We're just not going to get there in time, I'm afraid."
