STAMP OF A CHAMPION Legendary Grand National winner Red Rum is to feature on a set of stamps issued by the Isle Of Man Post Office next month.The stamp is a reproduction of a painting owned by trainer Ginger McCain, who sent out Red Rum to win the Aintree spectacular in 1973, 1974 and 1977, and has been given the approval of The Queen. The gelding`s owner Noel le Mare lived on the Isle Of Man.Heavy rain has put today`s meeting at Wetherby in doubt forcing officials to hold an inspection at 6.45a.m.'We have had a downpour today and it is still persisting with water starting to stand in places,' said racecourse manager James Sanderson.
