This series of Ramblings is themed 'Ramblings Revisited' as Clare catches up with people she walked with once before.

In 2005 Clare rambled with a group based at the Radbrook Day Service centre in Shrewsbury, for people with mental health difficulties. The group had been running for ten years at the time of the original programme, but in the intervening years the Day Service centre was closed and the walking group folded.

However one of the walkers in the original programme, clinical psychologist Penny Priest, has continued her interest in the mental health benefits of walking and introduces Clare to psychologist Guy Holmes who began a similar 'walk and talk' group in Shrewsbury which allowed original members to continue walking, and also brought new members on board.

In this series Clare Balding revisits some of her favourite walks and walkers from past programmes.

Here she travels to the Hopetoun Estate, just west of Edinburgh to meet up with a group of women she first met twelve years ago. The Monday walkers have been together for over twenty five years, when they first met Clare, their average age was early sixties, now it's mid seventies. They explain that although walking still keeps them fit, they do now tailor their routes to take account of the passing years. A wee dram may still be part of their days outings but skinny dipping is accepted as a past pleasure.

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.

In this new series Clare Balding revisits some of her favourite and most memorable guests. Eleven years ago she joined Tom Isaacs in West Wales as he walked the entire coastline of Britain in an attempt to raise money and awareness for research into a cure for Parkinson's disease. Tom had been diagnosed at the exceptionally young age of twenty-seven but has always been determined not to let his condition get in the way of him leading a fulfilling and productive life. Clare now walks with Tom and his wife Lyndsey, along the river Chess, close to their home just outside London.

John McCarthy is this week's guest presenter, while Clare is away.

The theme of this series of Ramblings is listeners' walks .Today's guests are volunteer rangers on the South Downs Way, Anni Townend and Ian Lock. Anni wrote to the programme to suggest we walk with her on a six mile stretch of the Way from Housedean Farm to Southease. This is her 'patch', which - as a ranger - she walks every month carrying out conservation work including scrub clearance and hedge laying, as well as improving public access and surveying wildlife and plantlife.

This week's walk is a little unusual. The guest, Cathy Dreyer, wrote to the programme to suggest we join her on a short, local route which she has chosen to walk 365 times.

Cathy began her project after reading the first few pages of Robert Macfarlane's book, 'The Old Ways'. She was filled with envy at his freedom to walk in exciting, far flung places. But rather than moan about her domestic responsibilities, Cathy thought she'd respond by doing a very short walk, 365 times over.

Cathy says she is using the walk to examine "what's really there" in both the natural world and in her domestic life as a parent which is repetitive and intimate, going over and over the same worn but wonderful ground. Motherhood and work means it's taking longer than a year to complete the project, something Cathy is chronicling in a blog www.walkinginacircle.wordpress.com

The theme of this series of Ramblings is listeners' walks, and this week's presenter is a previous Ramblings' guest: the broadcaster, actor and musician, Toyah Willcox.

This week's Ramblings is presented by the broadcaster and musician, Dougie Vipond, who took over the map and microphone on a beautiful July day when Clare Balding was away.

Dougie joined an amazing young girl, ten year old Annabelle Asher, on a stretch of the Coast to Coast walk from Newbiggin on Lune to Kirkby Stephen.

With her parents' support, Annabelle spent the first couple of weeks of her summer holidays walking the entire 190 mile route in order to raise money for the Welsh Guards Afghanistan Appeal.

Lieutenant Colonel Rupert Thorneloe, was the highest ranking officer to die in Afghanistan. He was a pupil at the boarding school where Annabelle's parents teach, and where Annabelle lives. When Annabelle found out what had happened to Lieutenant Colonel Thorneloe, she was determined to raise money in his memory.

Always a keen walker - once turning down a trip to Disney, for the chance to climb Snowdon - Annabelle completed the Cotswold Way last year (for the same charity), and has her sights set on the Pennine Way.

Dougie Vipond was a founding member of Deacon Blue. For BBC Scotland he presents the rural affairs TV programme, Landward, The Adventure Show, and Sportscene.

Clare Balding is in Durham for today's edition of Radio4's walking series, when she joins Maggie and Keith Bell. They take her on one of their favourite routes from their home, Crook Hall, through the outskirts of the city and along the river. The couple now use walking as a time to catch up, hold business meetings and relive memories of their courtship, when they both arrived in the city over thirty years ago as students.

Clare Balding is in Northumberland to join the walking group from the local women's choir, Wercas Folk. It was formed over eighteen years ago by the well- known folk singer and composer, Sandra Kerr. They set off from the village she lives in and loves very much, Warkworth. Wercas Folk, an unauditioned group, specialise in singing new and traditional folk songs about the area, its people and its history.

Many of the original founder members are still in the choir and they explain it's not just the singing that keeps them turning up week after week. The group have developed a collaborative and mutually supportive ethos that has forged strong friendships, resulting in them enjoying social time together even away from the rehearsal room and concert hall. They regularly escape from home and family for weekends away to walk, talk and indulge in the odd glass of wine.

As they set off on a circular route around the village they talk to Clare about the role the choir plays in their lives and the joy of singing and walking together.

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.
