A professional golf coach hopes to have broken the world record for the number of 18-hole rounds played in a single day – five!
Warren Clark played 90 holes in a single day, in a bid to create a new Guinness World Record.
The team at Guinness World Records is now reviewing all the evidence – video footage, images, time stamps, volunteer statements and so on. He has been told verbally that there is no reason that he shouldn’t have set the record, but he will hear back from officials in a few weeks.
Starting at 5am at Horsham Golf Park in West Sussex and finishing at 7pm, Warren played five full rounds of 18 holes back-to-back, without a playing partner, and under strict Guinness World Record conditions monitored by volunteers.
For Warren, who is autistic and faces reading and memory challenges, the attempt was about far more than golf. It was a personal stand against the limits that society can sometimes place on people with disabilities and an inspiring message to anyone who has been told they ‘can’t’.”

Commenting on his achievements, Warren said: “My aim with this Guinness World Record attempt was not to gain attention or raise funds. It was to show that no matter your abilities or circumstances, you can push yourself, challenge your limits, and live your dreams. I wanted people, especially those who have been told they can’t, to see that barriers can be broken. I know what it’s like to feel overlooked or underestimated, but golf taught me that with focus, patience and resilience, you can keep moving forward, one shot at a time. This wasn’t just about playing 90 holes in a day – it was about proving to myself and others that if you commit to the journey, no matter how tough, you can achieve something you once thought was impossible.”
Warren’s journey to this moment has been anything but easy. Growing up, he and his mother, who was later diagnosed with autism herself, overcame domestic violence, poverty, and learning challenges. At age ten, Warren discovered golf, a passion that would become his career and his platform for change.
That platform took shape in 2016 when he founded Warren Clark Golfing Dreams, a charity dedicated to promoting inclusion, diversity, and community engagement through golf and other accessible activities. Achieving full charitable status in 2020, the organisation now runs coaching sessions, inclusive sports programmes, and wellbeing initiatives for people of all abilities.
Warren concluded: “I want every person who hears my story to believe they are capable of more than they think. If one young person picks up a golf club, or simply decides to chase their dream, because they’ve seen what’s possible, then this journey will have been worth every step.”
Edit: Since posting this article, several people have contacted us to say people have played more than 90 holes in one day before (although not necessarily more than five 18-hole rounds on the same course under Guinness World Record conditions). For example, Eric Byrnes played 420 holes in 24 hours at Half Moon Bay, California, in April 2019. Robb James (using a cart), played 851 holes at Victoria Golf Course in Edmonton, Alberta, in June 2004. This year alone, Nick Brewaeys and Ross Lawrance broke a Guinness World Record at West Cornwall Golf Club by playing 184 holes in 21 hours and 45 minutes

Tony Clark also emailed us to say: “I hold the British record at 360 holes (20 rounds) in 22 hours, 40 minutes in July 1983 at Childwall Golf Club in Liverpool. This was accepted and featured in the Guinness Book of World Records in the 1984 edition. They only stay on for so long apparently as other records in other areas are added. I have a copy of the page it was listed on.”
