I think I am understanding this. This will enable me to burn fuel more efficiently whether from fat or glycogen?
I will try tonights ride, which is a recovery ride anyway, at zones 1-2. But its windy, and that will mean slower speeds. I find it hard to ride by my HRM instead of the speedo. Maybe I will just ignore the speedo.
I can't get it out of my head that I should be riding harder all the time to get faster. But I will heed your advice.
