I just wing it, whatever I feel like doing. Usually 3-5 rides a week, 20-50 miles each depending on whether I'm riding solo or group. Sometimes shorter rides if I'm mostly doing errands.
I stuck to the same non-schedule after both shoulders were injured in May (hit by a car) and I was cleared to use an indoor trainer. For 2-3 weeks I used the indoor trainer 3-5 times a week, watching TV. For the past couple of weeks I've mixed in one or two outdoor rides a week, although it's been ridiculously hot as you know living in Texas.
Nothing wrong with resting when you feel like you need it. I took Sunday off and will probably take at least Monday off -- felt queasy Sunday after a couple of rides in temps well over 100F. And I have a couple of medical appointments, so I won't have time to ride. Before the accident I'd occasionally take three days off if I felt stale and wasn't enjoying the rides. I try to avoid going more than a week without riding. It gets too easy to stop and harder to start again.
