Clare Balding walks in beautiful sunshine with one of the longest standing groups we've had on Ramblings. For over 30 years, Derek Fawcett and friends have met for an annual walk. They've known each other since they were at medical school and, despite going into different specialities, have retained a strong connection; they say this is best enjoyed while out walking. Today, they are in Laugharne in south west Wales. They follow a route from Laugharne Castle which takes in Dylan Thomas's former home. Thomas once described Laugharne as the 'strangest town in Wales' and based Llareggub in Under Milk Wood ('bugger all' spelt backwards) on the place.

Clare Balding walks to the extraordinary Dashwood Mausoleum, near High Wycombe, with Julia and Lee Clements and their daughter, Cerys. Cerys is nearly six years old and has cerebral palsy, so joins the walk in her off-road buggy. Together Julia and Lee discuss how they have adapted to life with a profoundly disabled child; Julia says she has become a 'fighter', especially for the right to give her daughter blended 'real' food, through the tube in her stomach, and not just formula milk which is the accepted norm. Lee says he once defined himself by his achievements at work, or in running marathons, or going for very long walks whereas, now, he values even the shortest of outings with Cerys - navigating kissing-gates, or pushing her weighty buggy uphill is a joy and a challenge in itself.

Clare Balding is off to Little Switzerland in this week's programme, but she's not travelling far: Church Stretton, in Shropshire, earned its nick-name in Victorian times because of the area's Alpine feel. Her companions are Mark and Debbie, who met after both lost their spouses to cancer. Together with Ted, the wire haired Dachshund, they are attempting to complete every route listed in the book "50 walks in Shropshire". They have just passed the 20 mark. Today's walk takes them to the trig point of the Long Mynd, from there they retrace their steps back to the top of Town Brook Hollow and return over the top of Yearlet Hill and Ashlet Hill and back into Church Stretton.

Today Clare is walking in Surrey with a group of asylum seekers who are former detainees of the Gatwick Immigration Removal Centres. Alongside them are volunteers from "Refugee Tales" which is a project run by the Gatwick Detainees Welfare Group; it involves monthly walks as well as an annual event which combines walking and storytelling. The idea, they say, is to "reclaim the landscape for the language of welcome". Over 50% of those held in Immigration Removal Centres are released back into the UK community though their cases may be unresolved, their living conditions precarious, and their future uncertain. These walks give the former detainees a chance to meet up with their friends, enjoy the countryside and - for just a few hours - forget their challenging and unknown future.

Today the group is in Reigate. The group will walk from the station to the top of Reigate Hill, then along the North Downs ridge where there are views towards Gatwick and the detention centres. They then work their way back along the Pilgrim's Way, and return to the station..

A chaotic and lively dog-walk on Hembury Fort near Honiton in Devon kicks off the new series. Nigel, the rebellious Golden Doodle, upstages Clare Balding and guests.

Clare's human companions are Amy, Jenny, and Anna. They met at the school-gate and formed a strong bond that has helped them through many health challenges. Jenny's thyroid problems led unexpectedly to her launching a successful dog-walking business.

They take Clare on one of their regular walks, across Hembury Fort near Honiton, and explain what friendship through walking means to them.

Clare Balding takes a walk along the banks of the Severn in the company of the country's most prolific travel writers, Christopher Somerville who's also the walking correspondent of The Times. They begin their six and a half mile walk in the Gloucestershire village of Purton which lies on the east bank of the River Severn, Christopher's childhood village of Leigh is not far upstream. He talks to Clare about the role walking has played in his life and how it became a way that he could reconnect with his late father.

Clare Balding joins Gill Callow, a teacher from York who takes her on a favourite six mile route around the city. Walking has always been an important part of Gill's life; a joy to share with friends, a way to appreciate the wonders of the British countryside, a stress - buster from intense days in the classroom and now vital to help her come to terms with the loss of her partner, Martin. Gill talks to Clare about how she introduced him to the joys of walking , the long distance routes they tackled and the plans they had for the future. She finds walking a good way to remember him and the many happy times they shared.

Clare Balding walks in the Peaks with Maxwell Ayamba, who founded a rambling group for other black men, from Sheffield, to help improve their health and well being. Clare joins the group as they leave the Moorland Discovery Centre and set off across the Moors. They explain to Clare how the group has helped improve their relationships as well as their health and Maxwell describes the art of riding crocodiles.

Clare Balding joins archaeologist, Charlotte Frearson and her dog, Indy, on their daily, five mile walk to work. A few years ago Charlotte was suffering from crippling anxiety, her doctor suggested medication or a dog. After detailed research Charlotte decided a whippet would be better than drugs and she bought Indy, short , of course, for Indiana Jones. Everyday they walk from their home in Crouch End, across London to UCL's Institute of Archaeology in Bloomsbury. It's hard to know who enjoys the walk more as Charlotte has the chance to reflect on the antiquities that might lie beneath their feet and Indy has the chance to hunt out tasty morsels on the pavement. As they take their favourite route from park to park Charlotte explains to Clare how Indy is now being assessed to be a Pet As Therapy dog, not just for her but for the students who sometimes find it easier to talk to him than their tutors.

Clare explores the beautiful beaches of Aberlady Bay, East of Edinburgh. She joins the pupils, parents and staff of Saltersgate school which supports children and young people who have additional learning needs. Mary Higgins is the outdoor learning teacher and she's discovered that for some pupils, a long walk on a Monday morning sets them up for the week. She's thrilled by how far and well they ramble and joy they derive from being outside whatever the weather. With special dispensation, some of the parents come along to explain to Clare the pleasure and benefit their non-verbal sons gain from this weekly adventure.
