A year spent with the swimmers at London's unique swimming ponds.
In a world of constant flux and chaos, it's almost a shock to discover some experiences remain natural, unhurried and unchanged. In the middle of metropolitan London lies Hampstead Heath, 320 hectares of forest, parkland, wildlife plus three swimming ponds. People swim in them all year round, whatever the weather, just as they did in the time of Keats and Constable, and our cameras filmed them over 12 months as they swam, laughed, sang, complained, ruminated, philosophised and simply sought respite from all that life threw at them.
