A time trial and prologue specialist, Boardman won the inaugural men's World time trial championship in 1994, won the individual pursuit gold medal at the 1992 Summer Olympics, broke the world hour record three times, and won three prologue stages (and consequently wore the yellow jersey on three occasions) at the Tour de France.

Boardman used the Lotus 108 time trial bicycle designed by Mike Burrows and built by the sports car manufacturer Lotus. Later he worked with the UK carbon fibre bike specialist Hotta, to produce other time-trial frame designs, which he raced in various events including world championships, and Olympic games. He is now involved in producing commercial and competition bikes with the Boardman Bikes and Boardman Elite ventures.

Boardman has also worked to promote walking and cycling across the UK, becoming Greater Manchester's walking and cycling commissioner in 2017, Greater Manchester's Transport Commissioner in 2021 and most recently, Commissioner of Active Travel England.

In 1992, he was awarded an MBE for services to cycling. Boardman was appointed Commander of the Order of the British Empire (CBE) in 2024 Birthday Honours for services to active travel.
