Dan Pullen, a southeast Asia specialist at tailormade operator Audley Travel, has completed 2,000 miles of his 2,300-mile fundraising walk around Britain.

He is raising money for mental health charity Mind with his ‘points and peaks’ challenge, which includes the highest peaks in Britain’s 15 National Parks, as well as the extreme east and southwest points of the mainland.

Pullen set off from Norwich in April, in the Broads National Park, and is currently in Northumberland. He expects to finish the walk in late November, after climbing Ben Macdui in the Cairngorms.

Despite not being in a national park, he plans to climb Ben Nevis as he feels that it should take a place on his route as an additional peak, as it is the highest point in Great Britain.

“I wanted to raise money for Mind, as it is a cause that has a lot of meaning for me, and at the same time promote the significant benefits of walking for mental health,” he said.

“I also wanted a break from technology – I have taken a sabbatical from work to do this and although I’m using my phone to document the trip, I am really appreciating the break from spending every day at a computer.

“My final reason was wanting a personal challenge which puts me out of my comfort zone, pushes me and allows me to strive for something that hasn’t been achieved before.”

He has faced blistering heat, storms, 60mph winds, temperatures of -5C, a chest infection and a displaced tibia.
