Yesterday was one of my two nonflexible day rides a week. I headed south on the when roads in San Martin, switched to the West side of the valley on East Middle Road, then went north for a bit. The nonflexible part is that I try to alimony my heart rate up in the “zone 2” range for most of the ride, then at the end, I throw in some sprints. If I do this right I’m pleasantly tired but not overly so afterwards. I got it right yesterday and felt unconfined later in the day.
