I've heard the term "Guilt-producingly slow" to describe a proper recovery pace - it sounds like you follow the adage.

If you're doing a 75 minute recovery twice a week, it sounds like you're doing more time in the saddle than I am (about 4-5 hours/week). I don't race, but I like to stay fit and challenge myslef a bit.

I was considering doing a short, easy ride - about 30-45 minutes at an easy resistance. I don't have a power meter so I will need to listen to my body.
