The Freedom Trail is a four day walk over the central Pyrenees to commemorate the World War II escape routes taken by allied servicemen and women and all those who helped them.
More than 40 miles from France to Spain, with a total climb of fifteen thousand feet up and nearly twelve thousand down, it was the most-used and toughest route to freedom.
Many Jews and others escaping forced labour also took this trek over the mountains.
Earlier this year Edward Stourton joined the walk to tell the remarkable stories of bravery, endurance and remembrance.
