The other day, I started to fiddle with it to line it back up, but then stopped myself. The three miles/hour I had lost last January had magically reappeared, simply by going back to the old methods. All is well.
I mounted a spare computer on the trainer bike last winter to monitor cadence a little more accurately, and thought I'd be interested in the miles. The reality was that I wasn't riding near as far as it felt like I was. None the less, the workouts on the trainer were intense and well worth the effort come spring.
