I raced road bikes throughout my 20s. A few days ago I hit the 10 year anniversary of my last race. At this point in my life, I can barely relate to the person who practically organized their whole life around racing and was deeply embedded in the local scene. But I completely relate to your feelings about the season coming and going. Even a few years after hanging up the cleats, I would still sometimes get the itch to drop into my city's local crit. There is something a little cultish about bike racing that is hard to give up. I don't know anyone who managed to have a healthy relationship with it for more than a decade. But it is a lot of fun at its best.
