Leigh professional Andrew Baguley and clubmates Peter Bean, Steve Dagger and Paul Sherwood played 72 holes in 14 hours to raise £3,000 in the Macmillan's Longest Day Challenge to help people living with cancer.
The marathon men teed off at the Lancashire club at 5.30am and all told shot an impressive 49-under-par which included 31 birdies and equated to 337 stableford points - and they only lost nine balls!
"Two scores counted on each hole and we got round so quickly that we even had time to stop for a spot of lunch," said Baguley, a former PGA Cup player.
Bean said: "We wanted to take on the challenge because my mum was diagnosed with cancer in 2006 and she has received fantastic support from the organisation.
"It was no easy feat but we were spurred on knowing every single hole will be helping people living with disease."
The top four teams from across the UK - calculated through combined scoring and fundraising totals - will go on to compete for the Longest Day Golf Challenge Trophy in Portugal in October.
And teams that raise £1,000 or more in sponsorship will also be entered into a prize draw to win a personal clinic and nine holes for three players with Shaw Hill's Ryder Cup hope Nick Dougherty at Wentworth.
