Three schoolboys from Bo'ness are preparing to take on the challenge of walking the West Highland Way this summer.
Owen Watkins, along with his mates Aaron Masters and Findlay Macinnes, who are all 17, have set a deadline of just six days to hike the 96 mile route from Milngavie to Fort William in June.
They're ditching a 'lads holiday' this year and instead are going to stay at home and raise cash for the Teenage Cancer Trust.
A GoFundMe page has been set up, which has already raised almost £1,000.
Speaking to Falkirk Live, Owen said: "Instead of heading on a lads holiday, we have decided to stay at home and do something for a good cause.
"We are going to walk the West Highland Way in June and raise money for the Teenage Cancer Trust.
"Cancer can hit anyone, and we hear more no about younger people, people our age being diagnosed with it.
"There's no point in us doing such a huge challenge for nothing, so we all thought why don't we raise some cash and help others out.
The Bo'ness Academy pupils will be taking to Perthshire to walk some hills to get them both mentally and physically prepared.
Owen added: "Because we get free bus travel in Scotland, that means we can travel anywhere, so have decided to head to Perthshire and get some steps in.
"It's not going to be easy, but it's going to be done.
"We have a spread sheet all set out with what we need to do, and it works out walking about 21 miles a day.
"Our families have been greatly supportive, they have all donated and are looking froward to us heading off and taking on the challenge.
"We are really looking forward to it."
