There may be no light at the end of the fairway for these four men, but that won't stop them from trying to get a hole in one for two good causes.
Julian Ellis, Danny Chapman, Neil Newton and Paul Attoe are set to play golf for 24 hours straight in aid of Prostate Cancer UK and East Anglia's Children's Hospices (Each).
To play through the night, they will use glow sticks to mark out the hole, hazards and bunkers, and will play with glow-in-the-dark golf balls.
They will undertake the marathon challenge at Weston Park Golf Club, Lenwade, next Friday.
The four friends said the idea started with chat in a pub and snow-balled from there.
Mr Ellis, 41, from Middlemarch Road, Dereham, said: 'We got together four or five months ago and I said I'd like to do something for charity.
'I joked about a 24-hour golf event and to my surprise the guys said 'yes' straight away.
'We were hoping to raise around £4,000 but we have nearly done that already.
'If we can reach £5,000 I think that would be an amazing amount of money to raise.'
The team members are now in training for the event and trying to build their endurance.
As part of the challenge they have banned themselves from using buggies.
Mr Ellis said: 'I know some of the guys have been going to the gym and I've been doing a lot of walking and been on the cross-trainer.
'Some people say it is going to be easy, but it definitely won't be.
'We will make it to the end, no matter what, even if we all to have to hobble round.'
The foursome have already seen their efforts raise £3,600 and have received great support from sponsors and the companies they work for.
The players will continue even in a torrential downpour, although for safety reasons they will have to pause if there is lightning, and they are hoping that camaraderie will pull them through.
The night-time golf equipment has been provided by Corporate Golf Ventures.
The event starts at noon on Friday and ends at the same time the next day.
