A former soldier left unemployed and homeless is on the verge of completing an 8,000 mile charity trek across the British coastline.
To show his commitment, the 39-year-old has slept rough for all of his 8,000 mile journey, carrying his supplies on his back.
When I crossed Tower Bridge in London I had an escort with the blues and royals and the lifeguards either side of me - which was pretty amazing! I have been out on training exercises with the RNLI [flood rescue] teams and I got to drive Britain's fastest lifeboat, which was pretty awesome as well.
Nock was inspired after declaring himself bankrupt when his B&B went under, leaving him with massive debts.
The former corporal with the Staffordshire Regiment applied for 120 jobs but had no luck.
He began his epic trek nearly two years ago and has so far spent 20 months walking and raised £200,000 for Help for Heroes.
Nock has also found love on his fundraising tour; he met his new love Kelly after she turned out to encourage him as he walked through Kent.
Today he returns to his native Blackpool and is set for a hero's welcome.
