[1][2] Chris Etheridge entered the national British Sidecarcross Championship for the first time in 1985 and would compete at this level for the next eighteen years, racing mostly with Shane Skeats as his passenger in the early seasons.
[4] With a new passenger, Nick Brace, a new engine make, a Zabel, and the retirement of Paul Millard Etheridge started to dominate the national championship from 1991 onwards, winning six consecutive titles until 1997.
Etheridge had almost missed out because of a broken shoulder the week before the final round but rode despite the injury and against the doctors advice.
[1] Etheridge made a brief return to the competition when he raced in place of his son injured Jack for one event in Wooley Grange in July 2012.
From 1996 onwards his results and number of race participations declined again, Etheridge not finishing in the top-ten again in his final six seasons in the competition.
