Two charity champions are gearing up for another challenge this week to raise money for Children in Need.

Sam Renwick, a leisure attendant at Freeman’s Quay Leisure Centre in Durham, will be running a marathon on the treadmill – his first ever run at that distance.

He will be joined by his colleague Steven Gardiner, a health and fitness co-ordinator, who will be completing 100km on the bike alongside him.

To make the challenge even more difficult, both will be dressed in Pudsey costumes for the four-hour feat.

This isn’t the first time the duo have paired up to raise money for charity, having also completed a challenge which saw them do a burpee for every pound donated.

Other fundraising feats have seen a 24-hour spinathon where they took turns riding a bike for 24 hours, a 12-hour stairmaster challenge which saw them rotate to climb the equivalent of Mount Everest and the Great North Run.

Steven said: “We think this might be one of the most mentally tough things we’ve done as it is four hours straight with no rest, but we are confident we can do it.

“Within our jobs we have the opportunity to support charities more than other workplaces, so that’s what we do.

“It’s great for our members to support us and motivate us. We always put a target of £100 but really every penny will help someone, somewhere, so it doesn’t matter to us exactly how much we raise and we appreciate everything we get.”

The event will take place between 11am and 3pm on Friday, 17 November.
