Much as I think I could benefit as a cyclist from riding more frequently, I'm reasonably convinced that for me the best way to minimise time spent outdoors, whilst retaining fitness and sanity, is to carry on riding centuries at my normal frequency - 2 or 3 a month usually. Ordinarily that's the only cycling I do.
I've had a lot of fun over the last few weeks preparing routes in RwGPS which look interesting, stay local and don't duplicate. This is the one I did last Sunday, one of the most enjoyable I can remember, not least because of the peace and the unbroken blue sky:
The farthest point from my home was the junction at Defford, near Pershore, just under 16 miles away as the crow flies. This is an important junction as it enables the use of Eckington Bridge, the first ordinary road crossing of the Avon north of Tewkesbury, and if I couldn't allow myself to go that far route choice would be much reduced. For the time being I feel comfortable with taking 16 miles as the greatest permissible distance from home.
