Paul Harris from Bournemouth, aka 'The Warrior Walker', is trekking 6,000 miles along the Great British coastline for a second time.

It's just six weeks since he finished his first walk which took him a number of years. This time, he's hoping to do it in a year.

To do that he'll need to walk at least 19 miles a day with one rest day each week.

Paul's been chatting to Steve Harris about why he's doing it.
