The meeting scheduled for Fakenham on Tuesday has been abandoned due to ground conditions.
Some 14 millimetres of rain overnight prompted an inspection by course officials on Monday afternoon, with more rain forecast.
The decision was taken to abandon the meeting because of unsafe and false areas of ground due to excessive rain.
The course tweeted: "Racing tomorrow is abandoned due to excessive rain. Apologies for any inconvenience this may cause. Our next meet is on 28th Jan 2016."
