Clare joins Marian Spain and Paula Brunt as they explore a stretch of the King Charles III England Coast Path in West Sussex. After more than forty years working in environment and conservation, Marian is retiring later this year from her role as CEO of Natural England, the organisation responsible for creating and delivering this route which, at almost 2,700 miles, is the longest managed coastal walking path in the world. She says that overseeing its completion is her proudest achievement.

Marian’s lifelong connection to nature goes back to childhood walks with her mum, who taught her the folklore of flowers. She also recalls an inspiring biology teacher who opened her eyes to the science of the natural world. Growing up, walking was central to family life and a way of keeping up with older siblings. In her working life she enjoys taking colleagues on walking meetings, where conversations flow more freely.

They began their walk in Bosham and walked to West Itchenor, via the Itchenor Ferry which crossses Chichester Harbour. Paula Brunt, a campaigner with Disabled Ramblers, joined them midway to test a section of the route for accessibility. Tree roots prove an issue and cut the walk a little short.
