This series is themed 'Ramblings Revisited' as Clare Balding walks again with some of her favourite and most memorable guests.

In March of 2006 Clare Balding went rambling with Rosie Barrett and her two children, Rachael and Rob. They took her on their local walk around the Avon Estuary in south Devon. It had always been part of their lives, as a route for venting teenage tantrums or simply as a ramble to the pub, but after Rosie's other son, Hugh, died of cancer at the age of 19 the walk took on a deeper significance. The family, and a hundred others, planted trees in Hugh's memory on a nearby hillside and a new section of the walk was created through dense woodland.

For this programme Clare revisits Rachael and Rosie and follows the same route. Rob can't make it this time, but in his place is Jonno, Rosie's husband. It's now 11 years since Hugh died and of course the trees have grown; meanwhile Rachael now works in academia where her speciality is - appropriately enough - memory, landscape and therapeutic heritage.
