Absolutely, yes. Going through it right now. For the first 4-6 months this year I reached peak fitness only to have my events all canceled. Then the summer I worked on maintaining and targeted social rides with 1-2 people. Then all events for rest of year got canceled, kids were virtual in school, no racing on TV or on a schedule that I haven’t sync’ed with, and I lost some motivation.
I also go through periods where my hobbies of music and woodworking replace biking for a time. I wrote/recorded a bunch of songs, built a standing desk, and leaned in on my community service. It was a nice change of pace, and sometimes life happens.
Having said that, I am cursing taking a full month off. Starting at the bottom again, after being able to successfully hold fitness with even modest riding each week (2-3 rides). Ouch.
Life is busy, full, amazing, and hard. Bikes help most of the time. Sometimes other things do.
