“I’m doing alright – I thought I’d be knackered from the jetlag but it’s not been too bad,” Mr Hargreaves told BBC Breakfast.
“My legs are holding up, and I’ve had a bit of time to rest now.”
After setting off from Derby, where his parents grew up, Mr Hargreaves said the route had been the same as the one his dad took in 1984, but from Turkey onward, the journey began to diverge.
While his dad travelled through Iran in 1984, Mr Hargreaves was unable to do so and instead headed north through Russia, Kazakhstan, Uzbekistan and Afghanistan, before re-joining his father’s original route in Pakistan.
From there, Mr Hargreaves followed the original route through to Nepal, where he reached Everest Base Camp – and went one better than his dad.
“I had to beat my old man,” he said. “So I did Annapurna Base Camp too.”
After Nepal, Mr Hargreaves flew to Bangkok, before getting back on the bike to ride through south-east Asia, taking in Vietnam, Laos and Cambodia, before eventually finishing the journey in Australia.
