This. If you're creative, you can find a way to put together a long mileage ride without ever getting far from home. I have a 30 mile loop I can ride that has my house, my office, and my gym at various points on the loop. There is a hospital in the middle. Also plenty of roads inside the loop for variability. At no time on the loop am I longer than 5 miles from any of those stopping points.
