Navan & Thurles off Today's meetings at Navan and Thurles have both been cancelled due to frozen tracks. Both courses were hit by sub-zero temperatures overnight, and there will now be no racing in Britain or Ireland this afternoon. Turf Club press officer Cliff Noone said: "Both meetings are off following a severe overnight frost. "Both tracks are unfit for racing and temperatures dipped below minus 10C overnight, so they had no chance."
