David Knight said he was delighted to make a winning return to racing, after nearly four months out, following double hip surgery.
The four-time world champion from the Isle of Man dominated the weekend's two-day Dyfi Enduro, despite still completing his rehabilitation.
"I took it one lap at a time and it felt great to be back racing. I wasn't planning to compete," said Knight.
The Manx rider won both days to record a convincing overall winning margin.
Tom Sagar finished second with the Isle of Man's Danny McCanney claiming the third podium spot.
McCanney was pushing Sagar for second place but suffered two crashes in the wet conditions.
"I was riding well but the crashes set me back a bit," said the 19-year-old Gas Gas UK rider, adding "it was really good to see David making his return".
Knight topped all but one the opening day's special tests and won all four of Sunday's stages.
The eight-time British Enduro Champion added: "I know I need to be stronger before returning to World Championship competition. I didn't expect to be able to do two days after nearly four months off a bike."
The 33-year-old KTM rider will now have a month to prepare for the final round of the British Championship, which leads into the final round of the World Championship.
Meanwhile, Isle of Man rider Alex Rockwell missed the event with a broken hand.
