Clare Balding walks the final stretch of the South Downs Way, starting at the Sustainability Centre at East Meon. The group walking with her have all opted for a life that's as green as possible, and includes Mary Lewis who lives with her family in a yurt on the site of the former Naval Signals base where Tim and Maddy Harland run their green publishing company. Joining them is Alan McVittie of the Old Winchester Hill Hampshire Downs Reserve, and for the very end of the trail heading into Winchester, Andy Gatticker of the South Downs National Trail who met Clare back in Eastbourne at the start of the series.
