Fitness declining despite positive changes

Are there any organized events you’re interested in in the fall? I just finished my crit season for the most part, and am now training to do some fondos and things with climbs and what not. Used Plan Builder to give me a progression to work from. Once that’s done, I’ll stay off the bike for a while before working out a plan for 2022 based on target Crit dates, which probably means I won’t start base training in full until late December or early January.
