Dougie Lampkin further extended his advantage in the Appleyard ACU British Solo Trials Championship with a brilliant display in the fourth round, which was held just outside his family home town of Silsden.

Now a resident on the Isle of Man, Lampkin returned to Addingham Moorside, the venue where he learned his skill as a youth, to deliver a truly world class performance in front of a large local crowd on his way to a comprehensive victory in the Mackenzie Trophy trial.

Despite a disputed five as early as section three on the opening lap, Lampkin took control of the event from start to finish and looked strong and confident as he attacked the big boulders on the steep hillside course.

Incredibly, Dougie only dropped one more mark to complete his initial lap, an intermediate total that already put him four marks clear of Graham Jarvis after just 12 sections.

Although Lampkin suffered a second five, this time at section 11 on his second visit, he managed to maintain his lead, with Jarvis only able to match his lap score of seven.

The weather and sections deteriorated but Lampkin was at his absolute best during his final tour, posting his best lap of the trial.

With just four marks to add to his tally Lampkin ran out a clear winner of Jarvis, his winning margin of 11 marks confirming his superiority on the day.

Sam Connor recovered from severe food poisoning in Italy last week to claim third spot ahead of Manchester teenager Shaun Morris and Durham student Michael Phillipson.

Howarth's Dan Clark was sixth after a gritty ride that left some very good riders trailing in his wake, including Scorpa team leader and importer Martin Crosswaite.

The title chase now 'rests' until September 1 but Lampkin has six points in hand over Jarvis with only two events to come.

James Lampkin, Dougie's cousin, won the Expert class from yet another Lampkin cousin, Dan Hemingway, with Tranmere Park teenager Edward McIntosh posting his best national championship result to date.

"I had a good ride for the first two laps, then the rain came and the sections caught me for three failures. My marks just doubled," said McIntosh, who was running second in the overall order until the last lap. Cookridge teenager James Dabill took second place in the youth series - not a championship, but more of a way of bringing young riders into the British series. Dan Sherwin, from Roundhay, was fourth in the same category.
