( CNN ) -- An American amateur golfer is poised to extend an incredible world record on December 26 as he aims to complete his 600th round of 2010 . Richard Lewis holds the Guinness Book of World Records ' title of `` Most Avid Golfer '' after breaking the mark of most rounds played in a year when he finished his 587th on December 19 . The 64-year-old , who has played as many as 54 holes in a day , will take to the tee at the Four Seasons Resort and Club in the Las Colinas region of Dallas , Texas for his next milestone . He has played all of his rounds at the club 's TPC venue -- which hosts the PGA Tour 's Byron Nelson Championship event -- and its private members ' course at Cottonwood Valley . Lewis , who has walked an estimated 3,900 miles during the feat , explained how this achievement is the next best thing to being a professional golfer . `` When I was 10 years old , I wanted to be a PGA Tour pro , '' he told the tour 's website . `` But it never worked out for me . Now I have another quest , another goal , which I fully intend to complete in December . '' To commemorate his momentous 18 holes , Lewis will play alongside supporters who have paid more than $ 5,000 to compete alongside him when he starts at his usual tee-off time of 7.30 a.m . The funds raised will then be donated to `` The First Tee of Dallas , '' a local charity aimed at improving the lives of young people through golf . After his effort on December 26 , Lewis will continue to play until the end of this year , with his final total likely to stand at 611 . Lewis told the PGA Tour website that he has missed only 19 days this year -- all due to bad weather . He has lost 40 pounds during the challenge despite eating at least one pizza a day plus protein drinks to keep up his strength . Four Seasons club manager Rob Cowan has hailed the veteran golfer 's efforts . `` The detail to his quest is just amazing , '' Cowan said . `` Just eating healthy , staying healthy and getting ready for another round . `` In fact , I would say nobody in the 27-year history of the Four Seasons has gotten more out of his membership than Richard . ''
