Career
Farrell rode in short-track and scrambling competition in the late 1960s and early 1970s before taking up speedway, while also working as a motorcycle mechanic. During the 1974-1975 British Lions tour of Australia he was spotted in a North Qld vs Great Britain meeting by Lions team manager Wally Mawdsley and made his British League debut with the Exeter Falcons in 1975 alongside then four time World Champion Ivan Mauger. A broken wrist meant that he missed most of the 1976 season but he progressed on his return, reaching the Intercontinental Final in 1978.
A hand injury limited his season and the following season only lasted until April, when he suffered a broken leg while riding in a Midland League match against Birmingham, complications from the injury ending his career.
