Jimmy Higgins, a former teacher turned author, walked from the village of Neilston to Vimy Ridge, where his grandfather fought during the First World War.
He made the trip with his cousin, John McGuire, managing director of Phoenix Motors in Paisley.
"It was a really interesting and eventful walk," said Mr Higgins
"There were several stretches of road where it was hazardous being on foot, such was the traffic, so we had to be careful. But the scenery between Ayrshire and Yorkshire was consistently stunning.
The pair took a ferry from Hull to Zeebrugge, in Belgium, before setting off on the final 75-mile stretch of their epic walk to the Vimy Ridge battle site.
The pair set off on the trek to help raise funds to erect a long-overdue First World War memorial in Neilston.
Mr Higgins added:"We collected £300 en route through casual conversations with people, who would hand over £10 or £20 notes, which was very gratifying. Some people offered us gifts in kind - there were publicans who would give us a free drink, but we put money equivalent to the drinks into the fund."
Mr Higgins, who was born in Neilston, recently published his debut novel, Milltown, set in a fictionalised Neilston during the First World War.
It has been estimated at least 156 men from the area died on service in 1914-18, out of a population of between 3000 and 4000.
