Long-distance walker Nat Severs is packed and ready to spend the next year walking around the coast of Britain.
Weather permitting, the 23-year-old will set off from Southsea seafront this Sunday morning and head west.
He hopes to be home in time for his Christmas dinner later this year after completing the 7,000-mile trip.
As already reported in The News, Nat, who graduated from Cardiff University in 2008 with a degree in zoology, is hoping to raise money for the Stroke Association and Mammal Society.
Nat, of Gladys Avenue, Cowplain, said: 'I'm really looking forward to it now.
'The idea first came to me back when I was in college, when a friend and I talked about doing it.
'It never happened then but now seemed like an ideal time to do it.'
Nat will start off by heading towards the south-west of England.
He will carry on around the coast of Wales before heading up along the coast of north-west England and into Scotland.
He will then make his way down the east coast of Scotland and England before finishing.
Nat will make a quick detour home in August - for his brother John's wedding.
He said: 'I've got a tent with me and will be in that the majority of the time. I know a few people from my uni days all around the country though so I will be staying with people where I can.'
Nat's family, including his brother John, mum and dad Lesley and Martin, and sisters Rhiannon and Gianina, are hoping to join him at various points of the walk so he doesn't get too lonely.
Other than that he will just have an iPod and book for company.
He added: 'I've always loved walking so can't wait to get started.
'The part I'm looking forward to most is the west coast of Scotland as it is beautiful and remote and I've never seen it before.
'But its remoteness probably makes it the part I'm most wary of. The Pembrokeshire coast is also one part I'm looking forward to.'

He is due to set off from South Parade Pier at 9.30am on Sunday.
