Closed Country: Helen Glover in her Buckinghamshire back garden.

We were going to kick off this series with Helen Glover exploring Newlyn in Cornwall: on an RNLI lifeboat, and with open-water swimmers... However, at the last minute, Covid19 stymied our plans. Instead of the wild open countryside of Cornwall, she's reporting from the confines of her back garden, on the River Thames, in Buckinghamshire. Luckily, she's married to the naturalist Steve Backshall, so she has access to a ready-made expert who helps to explain the wildlife in their midst. Producer: Karen Gregor
