Wellbuilt men, at the peak of their condition, with years of racegoing experience behind them, stride confidently into Cheltenham racecourse on the first day of the festival. Three days later they emerge as gibbering, broken figures, emaciated, grey-faced and wretched. It takes a supreme human athlete to survive Cheltenham's ultimate test of moral, emotional and physical stamina.
