Joss Naylor, the farmer from Wasdale who became one of the our greatest fell runners, is about to embark on a special run to celebrate his 80th birthday.
So what is a good challenge at 80? Well for Joss it's running 30 miles from Caldbeck to Wasdale. And he's doing it to raise money for Brathay Trust, a charity that helps young people make positive changes to their lives. Fiona Marley Paterson has been to meet him.
