I have two thoughts: Years ago when I was working closely with a professional trainer for endurance MT bike racing, he had me take a full week off my bike before my "A" race which happened to be in the fall (The Vermont50). It seemed counter intuitive, but the results were solid. The theory being that the body benefits from a full recovery after a season of intense training.

Now skip ahead ten years and arrive at my second thought which is that I started a 1,000 mile tour last fall after putting less than 200 miles on my bike the entire 12 months prior. I was fine. My bike's geared low, I know my body, I was alone and I wasn't in a hurry.

You'll probably find yourself to be very strong and you might even be surprised at your comfort level after the rest. And if not, it shouldn't take too long to get back up to strength on the bike.
