In exceptional circumstances, a key Jump fixture that would have been abandoned  is delayed so that it can take place 24 hours later, with weather conditions improving.  Also during a prolonged cold snap, all Jump racecourses could be contacted at the beginning of the week to ascertain whether the conditions in any part of the country are less extreme, thereby making it possible to stage a Jump fixture when no other Jump fixtures could be staged.  All decisions are taken in the best interests of the sport rather than individual racecourses.
