Kershaw digs in at Deepdale.
Yorkshireman Simon Kershaw dominated from the word go to win an event which attracted more than 100 riders, floating his AM Beta through the rocks and climbs with unhurried ease.
Clubman A winner Mark Cameron, always strong on gutsy climbs, made his Sherco dig in and grip to lose only three in total - the best by far - while Mark Buckworth proved outstanding over the difficult rocks of section six.
It was tight in Clubman B but Guisborough's Richard Jackson wiped the cobwebs off his old Montesa to beat Jon McKinney, also from Guisborough, on most cleans rule, with Mick Watson third just one mark adrift.
McKinney blew it on the relatively easy climb over the rocks of No 5, losing four to Jackson's clean sheet.
Dave Almack was thereabouts, but a mark lost on sections two to five dropped him down the order.
Andy Waugh, Steve Magor and Best Over-60 winner Brian Hutchinson were the only riders to stay unpenalised on section one.
Dan Peace proved too strong for Ollie Kendra in Youth B and Zac Collinson topped the D class by three marks from Joe Faunthorpe though credit must go to all youngsters who nailed a finish.
