EVERY golfer knows that 18 holes is a gruelling task, both mentally and physically.
Dealing with 36 holes is at times quite unbearable.
Try playing four rounds, (that's 72 holes), in four different countries... all in one day!
That is the incredible feat that 74-year-old Frank Miller, from Copt Heath Golf Club completed in June.
What made the achievement even more outstanding was his ability to play each self-funded round on foot, although he admitted paying the price the following morning.
"It was exhausting, I could just about walk when I woke up, and I could hardly straighten my legs on the drive home.
"But at 74 years of age I suppose I got off lightly.
"That said, I'm very happy to have completed another memorable day."
Frank, a retired quantity surveyor, started doing 'golf marathons' after conquering 72 holes and dedicating it to a close friend of his who died in 2005.
But after endless nights of planning and preparation he set about playing one round in each of the four UK constituent countries - starting in Northern Ireland.
So at 3.45am on June 23, the 17-handicapper teed off at Belfast's Camalea with patient friend Peter Higgins matching every footstep despite not swinging a club due to the time constraints.
Just eight hours later Frank was ready to tackle his second course of the day, the tricky track named Helsby in Manchester.
Half way through and next up was an extremely hilly circuit in North Wales - Hawarden.
But determined to battle on, Frank finished within two hours and found himself in Scotland ahead of schedule at 6.50pm.
The marathon was completed at 9.30pm and the 19th, or should I say 73rd hole awaited.
The Alderbrook Road resident raised over £4,200 for Childline and St Mary's Hospice. He thanked all the contributors and his 'great friend' Peter as without him the task would have been impossible.
