4. The [Cyclo-cross] world championships have been held in Great Britain three times – London in 1973, Birmingham in 1983 and Leeds in 1992, when the home crowds were treated to a memorable British victory by Roger Hammond in the junior category. Hammond went on to win the British elite title eight times, land a podium place at Paris-Roubaix and become a successful directeur sportif.
