Arkle, probably the greatest steeplechase racehorse that ever lived, completely wrecked the handicap for any race he was in, he was top weight (approx 12st 10lb) and the others rock bottom (10st 4lb), named after a mountain in Scotland, as was another two year old in the same stable, Foinaven, it was thought as two year olds that Foinaven would be better than Arkle, both became legendary, Arkle for his prowess on the course and Foinaven for surviving the carnage at 23rd fence in the "National" and going on to win it with jockey Johnny Buckingham
