It has been said of concert musicians that if they miss even one day of practice they can tell. If they miss two days of practice, the audience can tell. I never did get to professional musician status but I did practice every day for a while and could tell by the sound when I missed a practice.
As for the bike, same as you. I was in good condition, even during colder months until January. Then, it not only was somewhat cold but it snowed on and off every few days so that roads where in poor condition for riding. Even at this late date, rain and sleet are predicted for the week end. The good news is that after spending some time with local maps, and a fine sunny day yesterday, I was able to link up a series of good riding quiet roads which I can get to right from the house. These roads lead to several centuries worth of good riding so that my riding territory is now very much larger.
