Britain's 100 metres runner Allan Wells never used starting blocks until a rule change forced him to do so for the 1980 Olympics in Moscow. He overcame that, however, to beat the pre-race favourite, Cuba's Silvio Leonard, by just three inches in a photo-finish to win the gold medal in a time of 10.25. At the time, the 28-year-old Scot was the oldest Olympic 100m champion in history.
