I aim for every day but something always comes up at least one day -- bad weather, work commitments, errands, doctor appts., etc. So it averages out to about 4 days/week. Sometimes I only ride 2 or 3 days, but then sometimes I'll string together some 5-day weeks.

I don't sweat it if I have to drive a day or two, and use those days to restock clothes, food and supplies, and return dirty laundry. Also, my legs get worn out if I ride too many days in a row. Sometimes I just need a recovery day.
