Copestake said the ride, completed over five days, was physically and emotionally demanding, with difficult weather conditions and steep sections along the route.
“It was tough,” he said. “The weather conditions were just changing hourly.”
He said that the fourth day of the challenge was particularly gruelling.
“I knew that was going to be the hardest day but about five miles up bank I wasn’t just pushing the bike, I was dragging it up. It was the weight on the bike.”
“There was times where I thought my body can’t take anymore,” he added.
He described one particularly emotional moment on Monday when he stopped off at a pub.
“Every emotion you can imagine just came out,” he said.
His wife Hailey said she was “really proud” of what Copestake had achieved in memory of his “one and only true best friend”.
