Mark Tostevin will tee off at 4am on Friday 6 September, and will play ever golf course on the island in a single day.
It's perhaps more a case of whole-in-one, than hole-in-one, as the keen golfer has challenged himself to tee-off at every Jersey course for charity.
Mark Tostevin is doing this in honour of his mother and grandmother, both of whom faced breast cancer.
He wants to raise money for ABC Jersey, the charity which supports islanders with the disease.
If that wasn't enough, he'll also be finishing at the ABC Gold tournament at La Moye, and shaving his head front of the crowd there.
The first hole will be completed at St Clement’s Golf Club, with tee off at 4am - head torch on.

Mark says the charity and the challenge is close to his heart:
“Both my grandmother and my mum have experienced breast cancer, and I know how hard it was - for them and for us as a family.
"It’s something that could continue to be part of our future, and I wanted to do something that raises awareness and gives back to the community that supported us when we needed it most.
"Golf is my passion - and if it can help others feel supported the way we were, then every early start and every swing is worth it.”
Each course is sponsored by a local business and the entire journey will be filmed for a special video documentary.
