Clare Balding walks in Somerset as the guest of The Tuesday Walkers of North Devon. Meeting at the village of Exford on Exmoor, they set out on a six mile circular route, which, like all of the group's walks, begins and ends at a pub. All the members are retired and take their Tuesday hike as an important weekly date in their diaries. While enjoying the scenery, the company and the exercise all have good advice to offer Clare, on how to ensure a fit, healthy, active and happy retirement. Producer: Lucy Lunt.
