This is the film of a unique physical challenge.

The legendary athlete Joss Naylor, retired shepherd from Wasdale, wanted to celebrate his fifty years of competitive fell running.

So on the longest day of the year he set off from Mungrisdale in the northern fells to run home to Greendale in the Wasdale valley.

Three camera crews, each of them giving him about thirty years, tried to keep up with him.

Friends and family, fell runners he's competed with over the years and commentators like Richard Askwith, author of Feet in the Clouds ran with him for part of the way and helped him through the pain barrier.

The result is an uplifting and challenging celebration of the achievements of a truly world class athlete.
