Yorkshire Challenge: Knaresborough duo lead the way on day of scorching hot scoring
The fourth annual staging of this hugely popular trilateral pairs event saw more than 350 golfers commence battle at Ganton, Moortown and Lindrick.
On count back they left Longcliffe's Michael Isaac and Steve Clarke in second place, with John Webster (Bedale) and Roger Parry (Rudding Park) third.
Andy Towens and Robin Griffiths, from Burnham & Berrow, also required count back to take first place at Ganton after Robert Kevan Yardley (Horwich) and Simon Moore (Turton) had matched their 44pt tally.
Normanton's Mark Griffiths and Tony Smith were winners at Moortown on 41pts, count back relegating Durham's Chris Brown and Dave Dickinson to second and John Fearn (Moortown) and Dave Leaf (Fulford) to third.
Walsh and Young offset an opening birdie with a bogey at the fourth at Lindrick before Walsh put the pairing in overdrive with five consecutive birdies from the seventh hole.
Young made it a sixth consecutive three-point hole for the pairing at the 12th and they added four more in the last five holes.
At Ganton, Towens and Griffiths contributed two birdies each on the way out and their momentum was only temporarily halted by a bogey at 10.
Towens produced a net eagle at the 13th and although a second bogey of the day followed at 15, Towens closed with three net birdies.
Leeds Union player Griffiths produced birdies at both of Moortown's opening two holes and another at the seventh.
He and Smith added one apiece on the way home for their 41pt total.
Defending champions Martin Barber and Brian Hill (Howley Hall) scored 37pts at Ganton, showing their class by recovering from a start that saw them amass just two points from the first three holes.
They bounced back with four birdies in a row and added three more on the inward nine, as well as a net eagle from Hill.
Each of the pairs will play all three courses to produce an overall winner.
