[3] His mother, Elsie Hargreaves, a cotton weaver,[3] remarried and Reginald took the name of his stepfather, an engineer and businessman called Joseph Harris.
Reg Harris left school without qualifications and his first job was as an apprentice motor mechanic in Bury, soon moving from the workshop to the salesroom.
[3] In 1935, he won his first race, a half-mile handicap event held on a grass track in Bury, and also started competing in individual time trials.
Harris moved from the motor mechanics job to a slipper factory, then, in early 1936, to a paper mill which he felt would pay him enough in the winter to spend the summer training and competing.
At the end of that season, he joined Manchester Wheelers' Club, and in 1939 won a major race in Coventry, leading to his selection for the world championship in Milan, Italy.
He travelled to Milan and had familiarised himself with the Velodromo Vigorelli when World War II broke out and the British team was recalled to the UK.
He was invited to race in Paris in 1945 and again impressed the crowds, and he was expected to do well in the 1946 world championships in Zürich, Switzerland, only to have his chances ruined by an over-enthusiastic pre-race massage.
After hospital, with a few weeks remaining to the games, training, competing and winning, he fell in a ten-mile (16 km) race at Fallowfield and fractured an elbow.
[3] Completing the rest of his preparation in a plaster cast, he had to be satisfied with two silvers, being beaten by Italy's Mario Ghella in the final of the sprint, and partnering Alan Bannister to second place in the tandem sprint (timetable constraints meant Harris's place in the kilometre was taken by another rider, Tommy Godwin, who won a bronze medal).
[3] He dominated Raleigh's advertising for a decade and, despite coming from a sport with no great following in Britain, he was as familiar as Stanley Matthews and Stirling Moss.
With more training behind him, he approached the British championship in Leicester in 1974 in more confident mood, and beat Trevor Bull to win the title at the age of 54.
