Clare joins two friends on what could possibly be the slowest walk between Land's End and John O'Groats. Hiking one week at a time (with a gap of several years when the Welsh coastline wasn't fully navigable) it's taken Iain McHenry and David Rowe 18 years to reach the coast of Dumfries and Galloway. That's where Clare joins them, on a beautifully sunny day, as they approach the village of Portpatrick on the remote Rhins of Galloway.

This is the first of two episodes recorded in the area: next week Margaret Hughes and Peter Ross take Clare on a section of the Southern Upland Way, starting in Portpatrick and heading north.
