Seeing how brave a young teenager has been while dealing with terminal cancer has inspired a father and son to play squash for an entire day.
Brett and James Meyer will try to get into the Guinness Book of Records by playing squash for more than 24 hours.
Their target is 30 hours, but anything above 24 will break the record.
A 13-year-old family friend of the Meyers has been battling leukaemia for 15 months.
The boy's family won't accept money but have suggested the Meyers raise funds for the Child Cancer Foundation.
"He has been very, very brave," Mr Meyer said.
"James came up with the idea for a squash marathon about seven months ago. We thought it was a neat way to combine the two and turn it into a little fundraiser. It's our little contribution."
They have raised $11,000, and are aiming for about $25,000.
Between them, Brett, 44, and James, 17, have been playing squash for about 39 years, and they're confident they can break the record. They will have to video the entire marathon, have a medical professional on-site and have two witnesses present at all times.
They are only allowed five-minute breaks every hour, which will be mainly used as toilet breaks and will allow just enough time to consume an energy drink.
Mr Meyer said: "We'll have someone firing up the barbecue all night and a DJ. A lot of our friends and family have promised to stay the whole night."
* Brett and James Meyer will try to break the squash-playing record from 9am at the Howick Squash Club on April 19. To donate money, log on to www.fundraiseonline.co.nz/squashmarathongwr/
