This year, I haven't done as many fast (for me) group rides. Instead, more "zone 2" or "conversational pace" longer rides. I can do 50 or 60 miles quite easily, but I notice more cramping problems than usual if I try to hang on to a fast ride, where I have to work hard on hills. And I'm definitely slower on these hard efforts.

I've gotten in a few faster rides and a couple of solo hard efforts over the last 3 weeks, and it's made a big difference. I'm closer to my 2015 speed now.
