Courtney was born in Braintree, Essex in 1961 and moved with his family to Workington when he was twelve,[2] and he began his speedway career with second-half races at Workington in 1977.[3][4] He joined the Barrow team in the National League the following year, moving to Middlesbrough Tigers in 1979.[3]
In 1982, he moved to Leicester full-time after a £15,000 transfer, and in the same year finished as runner-up in the European Under-21 final,[3][8] defeating Peter Ravn in a run-off for silver.[9]
In 1983, he was the Lions' highest-average rider, and represented England four times.[3] At the end of the 1983 season, Courtney requested a transfer and signed to ride for the Belle Vue Aces in 1984, and then King's Lynn Stars in 1985.
In 1986, he dropped back down to the National League with Middlesbrough, while also making fifteen appearances for Belle Vue. He helped the Middlesbrough win the Fours Championship during the 1986 National League season.[10]
A successful three-year spell at Berwick between 1988 and 1990 was followed by seasons at Glasgow, Rye House and then Middlesbrough. He was sacked by Middlesbrough at the end of the 1993 season after an incident involving a fire extinguisher at a hotel in Swindon.[2] This effectively triggered his retirement from the sport, Courtney later moving into the building trade.[2]
After being arrested in May 1997, Courtney was sentenced to six years in prison in 1998 for his part in a plot to import cannabis with a street value of £500,000 into the UK.[2]
After seven years away from racing, Courtney, released from prison on licence, returned in 2000 with Glasgow, moving on to Trelwany midway through 2001. He moved on to his final club, Rye House, in 2002, finally retiring at the end of the 2003 season, after which he became a mechanic, most notably for Chris Harris.[11]
