COWLING builder Nathan Wrigglesworth won the expert class in Bradford & DMC's Timperley Cup Trial at Yarnbury on Sunday.

The second trial in the Yorkshire Centre ACU championship series was an ordeal and a day of survival for 80 competitors and 20 observers high above Grassington.

No shelter, plus an Arctic blast of rain, sleet and snow, tested all involved but, despite the freezing conditions, only a dozen competitors dropped out.

The disused Yarnbury lead mines, with a 200-year old history, formed the back drop for the action. The shallow valley at Benson's Allotment housed seven sections and afforded minimal protection, with the waterfall climb taking the main force of nature and modest marks.

The moor above featured rocky climbs in the shallow streams followed by a plunge into Bolton Gill.

Sheep Fold was on the way in and featured the stepped rocky gulley.

Course planner Wrigglesworth won the championship class from Guiseley's Joe Jennings, while Keiran Child put in a Class A youth-winning ride that got him third overall, with Keighley's Jacob Snowdon third in the same category.

Sam Boocock headed the Inter class by three marks from Yeadon's Louis Haley. Barnsley's Neil Savage made his trip worthwhile by heading Ilkley heating engineer Andy Tales and Baildon former sidecar ace Nigel Scott.

Falcon's Ian Haigh was at home on the course as he roams on the Pennine hills, whereas Rob Hardisty dwells in the flat lands of Harrogate.
