Olly Spry is taking on a golfing challenge for charity, starting at dawn and ending when the sun sets.
The father of three will be tackling the 32°C heat at La Moye Golf Club.
Olly chose today to do the challenge as it's the eve of the summer solstice - so one of the longest days of the year. It also happens to be set to be the hottest day of the year so far.
He is doing it all in aid of Cancer Research UK.
Olly says his firm was thinking of what to do for charity this year, and he wanted to do something fun, raising money for a cause close to his heart.
"I know lots of friends and family who've been affected by cancer, some worse than others.
"Some have been amazingly resilient, and some have struggled somewhat.
"I know the incredible work this charity does, and I wanted to make a small difference to see if I could help it in the future."

Olly is putting a twist on the day by dressing up in different fancy dress and setting himself little challenges.
"It's not just about golf, it's about me dressing up in lots of different outfits, I'm going to wear a wedding dress that I wore last week on the high street, lederhosen, a beer bottle and a couple of other things.
The keen golfer also joked that he will be using different 'clubs' throughout the day:
"A croquet mallet, cricket bat, frying pan and maybe a snooker cue, just to mix it up and make it more entertaining for people to watch."
People can donate extra money to set him challenges, choose an outfit or a club, sponsor a hole or even enter sweepstakes on how many holes he may reach.

All the money raised from the dawn 'til dusk challenge will go towards supporting Cancer Research UK.
There are 4,720 people on Jersey's cancer registry, with 1,058 people diagnosed annually.
Non-melanoma skin cancers affect 42% of people with cancer, with Jersey seeing higher than average rates of skin, breast, neck and head cancers, when compared to England.
It is predicted that 1 in 2 people in the British Isles will be affected by the disease in their lifetime.
People can help Olly reach his fundraising goal of £7,000 Cancer Research UK donation page.
