The thought of tackling three mountains in one day can seem a daunting task to many climbing enthusiasts.

But for a group of north Norfolk fundraisers three is not enough and they have instead upped the ante when they attempt to scale four peaks within 24 hours this weekend.

The ambitious quartet are climbing in aid of the Break children's home in Mundesley, which provides respite care young people, where they all work. Their monumental climb, which will take in England's four highest peaks totalling more than 10,000 feet, is part of a 100-day challenge staff at the home are taking part in to send the children on a once in a lifetime holiday.

Marlon Fulcher, from Cromer, is among the team taking part in the climb in the Lake District on Saturday and has been preparing for the challenge by walking in Dorset and scaling the steps of the town's lighthouse.

The 36-year-old said: 'That's 50 metres a time and it's the closest thing we have to a hill in north Norfolk. I was going up and down 12 times in a row, trying to run parts of it where possible.'

Mr Fulcher said he had heard of others trying and failing to complete the four peaks challenge but thought he and his team would make it.

'We're a really determined bunch, we're going to plough on through to the end,' he added.

He will be joined on the walk by Scott Olivey, 40, from North Repps, Rob Kavanagh, 24, from Cromer and Tom Brown, 28, from Aldborough and together they hope to raise �1,000.
