Over the winter and through the spring, I put together a set of walks in and around Harefield to chime in with the Heart and Lung initiative at the Harefield Practice, in conjunction with the hospital next door. There is now a set of fourteen walks, ranging from 1.2km to 15.3km (don’t worry, the longer ones may be broken up at bus stops along the way), on streets, lanes and towpaths, and over parkland, farmland and woodland.
The webpage has a link to an accompanying document which gives gives full details with photographs.
