For me, both swimming and walking almost always inspire writing ideas. Walking in our new region, no problem - loads of paths, quiet roads and woods. The swimming aspect is more problematic. I never anticipated buying a house with a pool but our last abode had one and over the years it provided masses of exercise, great pleasure, and general inspiration for my plot lines, characters etc.
In our new house there is no pool, a small river, but not big enough to get into. The loire is reachable by bike but not advised swimming, the currents being very strong. So I've been on the look out for other wild bathing options. Of ponds noted on recent cold winter walks the one featured below has distinct possibilities.
Pond swimming is probably my favourite form. Possibly because of all the trips my mother and I made to the Hampstead ladies' pond in the 70s - a great green-brown pool of soft water to be shared with ducks and other women as they quietly breast-stroked their way around, hair covered by rubber, flower-decorated swimming caps.
