SILSDEN'S Dougie Lampkin produced a clean ride to win Yeadon-Guiseley Motor Club's opening championship trial at Addingham Moorside.

The venue was blanketed by dense fog when 86 riders unloaded their machines. Visibility was down to finding the section flags on the four-lap, ten-section course and even the rock escarpment which towers over the area was invisible.

Despite the gloom, Lampkin piloted his Vertigo through every section without penalty to beat cousin Dan Hemingway, who was set for second place until the eighth and tenth section up on the escarpment, when he tap-danced through section nine.

Those marks let in Embsay's Aran Drachenberg on most cleans. Thomas Housecroft and John Lydamore grabbed the inter and novice classes.

Keiran Child contained Joe Faunthorpe on most cleans after the Bradford teenagers levelled on scores. Clubman A winner Paul Kettlewell lost the majority of his 11 score on the rocks by the lower boundary wall where the ground was on the soft side.

Yeadon-Guiseley will run the Centre Championship trial at Keighley Gate on February 5.
