An enthusiastic young farmers' club proved they could go the extra mile by raising more than £3,800 for a bereaved children's charity.

North Walsham Young Farmers, winner of the Bond Cow Cup 2015 for best performing club in eastern region, sent 20 of its budding agriculturalists on a gruelling coastal trek over pebbles, dune and marshland in an 80 mile endurance feat.

At the Royal Norfolk Show, the club presented a £3,800 cheque which will enable children's charity Nelson's Journey to fund six bereavement packages for children who have experienced the loss of a loved one.

Sarah Ellero, secretary for the club, said its 40 members had chosen the charity after staff from Nelson's Journey came to speak to them.

'We walked from Great Yarmouth to Hunstanton on two nights' bad sleep. It was tough,' she said. 'It was basically like doing a marathon every day for three days. It was just the terrain on the beach that was hard.'

Gena Moore, corporate funding and marketing officer at Nelson's Journey, said the charity needs £500,000 a year to run well and staff were thrilled with the money raised.

It will pay for work include a full assessment of children's bereavement needs, one-to-one support and residential therapy at Hill Top outdoor activity centre near Sheringham.

'This is an amazing amount of money. We had no idea how much would be raised,' said Miss Moore. 'The difference between a child at 9am at Hill Top to then leaving at 4pm on Sunday – they're children again, just happy.'

John Withers, the 23-year-old chairman of the club, said the adventure had also been good news for the club's camaraderie.

'The walk was great for club spirit and made us all work as a team,' he said. 'We do a lot of social things together as a club, but this was very tough, we all pulled together.'
