Jim began his 7,500-mile trek in April and aims to walk the coast of mainland Britain for the Gurkha Welfare Trust.
More than 2,000 miles into his journey, Jim was nearing the Isle of Skye when things took an unfortunate turn.
After losing sight of his intended path, he was forced to walk along the beach when faced with large cliffs.
He felt he only had one option - to climb the cliff face - but became stuck on a ledge around 15 metres up.
Fearing he would be stuck for hours, Jim attempted to get off the ledge but fell onto the beach below.
“I woke up after a while and my head was bleeding really badly,” said Jim, 61, from Penistone. “I managed to call for help and in the end the coast guard had to come and airlift me to Inverness Hospital.”
Jim was told he had a broken thumb and a bleed on his brain but is recovering well in his motorhome he shares with wife Sue who joined Jim on his adventure.
“I couldn’t believe that it happened,” added Jim.
“I feel a bit daft, but I am looking forward to getting back to the route because I want to be out of Scotland before winter hits.”
