A team of wounded veterans and serving personnel have taken to the French Alps for high altitude training ahead of attempting to summit Mount Denali in Alaska.

Standing at 20,310 feet (6190m) above sea level, Denali is the highest peak in North America - and with a vertical rise of about 18,000 feet, is the tallest land-based mountain on Earth.

The group of six spent four days in Chamonix preparing for their epic climb, from mastering rope skills to learning crampon technique.

It was also a taste of what effect high altitude can have on the body.

Their Denali assent is part of an attempt by 65 Degrees North (65DN), a charity dedicated to helping WIS veterans and service personnel, to climb the highest mountain on each continent.

This will be their 4th, having already climbed Kilimanjaro in Africa, Acongacua in Latin America and Mt Vinson in Antarctica.

Founder of 65 DN, Rich North, is part of the team attempting Denali:

"It’s the highest mountain in North America and quite a ferocious mountain, 20,000 plus feet and one of coldest mountains on earth.

"So for us coming to Chamonix is an ideal training ground, we can rehearse, use all of the facilities the Chamonix valley can offer in order for the team to become proficient to take on Denali"

65 Degrees North seeks to help in the rehabilitation of wounded or damaged ex-servicemen and women by offering the opportunity to participate in challenging adventure.

A year ago, Royal Marine Joe Winch was diagnosed acute complex PTSD:

"I've been dreaming of being up somewhere like this for about 12 months.

"It's the environment as much as it is the activity. In normal life back down at the bottom of the valley, around people, around towns and cars, it's a real struggle. I get very easily overwhelmed.

"But up here, it's different. I can feel a lot calmer and I can think a lot more clearly - it's just a whole lot more happy."

The team depart for Alaska next month.
