Two adventurers from Orkney are attempting to jet-ski around the coast of Britain.

They aim to complete the challenge in just 14 days and raise thousands of pounds for a cancer charity.

Colin Gregg and Dugy Ward are used to tackling the seas around Orkney on their jet-skis.

Now are embarking on a high speed voyage covering almost 2,500 miles as they complete a circuit of the coast of Britain.

Colin said: "There's going to be some days that are very challenging. Some days will be lovely, I imagine. But if you don't have bad days you don't appreciate the goods days. And that takes away from it being a challenge."

Their jet-skis might look small for such an arduous voyage. But they're powerful and with extra fuel on board the two adventurers believe they're well equipped for the journey ahead.

Dugy Ward added: "We've been jet-skiing in Orkney for probably 15 years. In 2000 we jet-skied to Shetland - 112 miles on a stand-up ski.

“It was tough but this is a completely different thing. It's sitting down - but a lot more miles."

The pair aim to complete the challenge in just 14 days - one less than the previous record for the trip - and to raise substantial funds for the Macmillan cancer charity.
