Four men will walk, cycle and sail more than 100 miles around south Norfolk in a bid to raise hundreds of pounds for local community projects.

The group, who all work at Saffron Housing Trust in Long Stratton, will undertake the 24-hour endurance challenge for the Saffron Community Foundation (SCF) – a charitable organisation which provides grants for community organisations and activities across the district.

Today, the fundraisers – Adam Ronaldson, chief executive of the trust; Alex Neale, carpenter; Chris Staff, grounds maintenance worker; and Paul Harvey, maintenance assistance – were due to begin their gruelling day at midnight with a 13-mile walk from Diss to Harleston along the Angles Way.

They will then use mountain bikes to travel off-road another 22 miles towards the base of the Beccles Amateur Sailing Club.

Here they will jump aboard a sail boat, and with the help of a skipper supplied by sailnorfolk.org, will navigate 33 miles of waterways up to Trowse.

The group will then hop on their bicycles again to travel 39 miles before being waved over the finishing line back at Diss.

Organiser Graham Symonds said the aim was to incorporate a route which circled the communities who can apply to the SCF.

'We wanted to highlight something like SCF which, on the whole, is not too well known but does a lot of good work in the background for little groups that need maybe �200 or �300 for something,' he said.

He added that if the event was a success, he hoped to repeat the challenge next year and invite members of the community groups the foundation has helped to have a go themselves.

Mr Symonds said: 'The other side to it is we wanted to show that you can do challenging and adventurous things in Norfolk.

'We have sailing, there's plenty of bridleways, beautiful scenery to walk in, rivers for kayaking and canoeing, so you can do something physically challenging outdoors without necessarily having to go and find a mountain.'
