Big race is set to go ahead Frost and snow, which caused the abandonment of three of Saturday`s jumping cards in Britain, are threatening to disrupt the busy St Stephen`s Day programme, with some courses already planning to hold inspections.But officials at Kempton Park are optimistic racing will go ahead as planned on Wednesday, when the feature event is the £150,000 Pertemps King George VI Chase. Clerk of the course Brian Clifford said yesterday: 'It`s a bit frosty at the minute. 'We could have raced here yesterday, no problem, at noon but last night`s frost was more severe and around for longer. 'The forecast is very uplifting in that we are forecast eight degrees tomorrow so I don`t anticipate any problems at present. We should be okay.' Officials at Wetherby believe they have a 'reasonable chance' of staging their holiday fixture, which includes the Grade Two £35,000 Castleford Chase. There is also some optimism at Huntingdon despite a keen frost on Saturday night. Ayr racecourse has escaped the recent cold snap, with spokesman Chris Kennedy reporting: 'The going is good to soft and there are no problems at the moment.' And it is a similar story at Wincanton. However, prospects of racing going ahead at Sedgefield are bleak. Clerk of the course James Hutchinson explained: 'We are going to inspect at noon tomorrow. There will also be a precautionary inspection at Market Rasen today to assess the chances of racing going ahead at the Lincolnshire track. The milder weather needs to arrive to rescue Towcester`s fixture. Hereford is also in doubt and the local stewards will hold a precautionary inspection at 7a.m. On Wednesday. The only Flat meeting on is on the Fibresand at Wolverhampton.
