So for pretty much anyone who is not a full time pro, there are better balanced strategies. HIIT is the other end of the extreme, but is at least practical. I do something in-between, but always with plenty of intensity all year round.

Henderson says that people typically doing a couple of 2-3 hour low intensity rides per week “base training” throughout the winter months are the ones really wasting their time and would benefit more from some intensity.
