Ride on Monday and Friday to start. Give you 3 days in the middle of the week and 2 days on the weekend to recover. Then when you feel you can add another day add Wednesday. Then you get a day off in between the ride days. Lather rinse repeat for Tuesday and Thursday as time goes on. I am still stuck on the 3-4 day a week rides. I also workout once i get home in the evening so that might play a part as well.

Either way, that is what I suggest.
