A DEDICATED team of fundraisers are using the Examiner's Charity Challenge Walk as a "training session" for a more ambitious hike.
Tony and Sue Thomas and their team are taking part in the walk on May 22 to raise cash for children's charity the NSPCC.
But the six-and-a-half mile trek will be a mere "warm-up" for a 35-mile North Yorks Moors Challenge Walk in June.
Tony, 49, of Tofts Grove, Rastrick is a former member of Huddersfield Pendragon Round Table.
He works for a software company and is also a magistrate in Halifax. Sue is the NSPCC branch treasurer.
Tony said: "The idea for the walk evolved last year, over a pizza and a glass of wine.
"This is the inaugural event and we have already got 200 people who have pledged to take part in the 18-hour "Can You Hack It?" event.
The challenge is along the southern boundary of the North York Moors National Park, from Kirkbymoorside to the outskirts of Scarborough, and has to be completed within 18 hours.
The team aims to raise thousands of pounds for the charity.
Anyone wanting to join the NSPCC team for either the charity challenge or the North Yorks Moors Challenge walk should contact Helen Verity on 01422 339515 or the appeals office on 0113 2299313.
