Second check at Kempton
This afternoon's all-weather meeting at Kempton is subject to a further inspection at 9am.
Officials announced an early-morning check for 7.30am after the Sunbury course was hit by significant snowfall on Friday.
With the snow having now relented, work can begin in an attempt to get the track fit for racing this afternoon.
Clerk of the course Barney Clifford said: "It has stopped snowing and the troops are working hard to try and get racing on. We'll know if this is achievable by 9am."
