Starting up officially in AZ too. But not for me.
Initially in March with no group rides I struggled with motivation for longer solo rides even though for two decades have commuted 22mi total daily every workday so have a lot of solo experience.
But after a few longer solo rides I started to like them better as they are more efficient time wise with no long stops and no periods where I want/need higher output and more concentration on my effort vs. group riding dynamics. And some of those certain people are not there to annoy me with their odd riding styles. I also like being able to change my route on the fly.
Of course I miss the socialization, competitive aspect and some elements of group dynamics. It can be hard to push oneself solo for a flat sprint, but I still work the hills hard. At least with social media ride posting apps I can try for best time for the day or year for some motivating competition as many of my cycling friends ride similar parts of routes.
