Well, I do lots of short rides. I mean really short, 10-15 miles. One day a week I usually do a short ride at 5:30 AM, as I can't commute any more.
If I get one medium-ish ride during the week and one longer ride on the weekend, I'm good, plus a couple of really short ones.
I've lost my riding partner (Hirakukibou) for the summer, as she is leaving on her cross country tour (the nerve of her

). It's easier for me to go out with her and do 40 miles at 6AM on Wednesdays and be back in time for my afternoon clients. If I do the group ride, it has to be a start place close to where I live and I have to skip the lunch. I will do some of these this summer, but, it stresses me.
I stopped worrying about this stuff after I was sick a few years ago. I spent one summer mostly doing errand rides and I think after that, I realized how quickly miles added up, I started doing more short rides just for fitness.
Between the rides, my classes at the gym, and some hiking, I'm good. I know I get antsy if I miss a couple of days, but sometimes, as my DH says, we want to be "regular" people.
