Saturday’s card at Warwick, which included the Grade 2 Kingmaker Novices’ Chase, has been abandoned due to a waterlogged track.
Clerk of the course Tom Ryall said: "We had 36mm in total yesterday, it started about 4am and carried on through to midnight.
"When we came in this morning, parts of the back straight where it runs parallel with Gog Brook are waterlogged as that was put on red alert last night, while the owners and trainers car park has flooded and that has spilled on to the track.
"We are basically about 50 per cent under water, so there is really no hope of racing."
Elsewhere in the UK, Uttoxeter has also been abandoned on Saturday due to heavy rainfall.
