I think the key here is that in your off season you can (and should) hit the different training zones… but your need to 100% recover from them before doing another one. And you should never “go to the well” at any time. It is important to not over do it too early or you’re fried come mid-season. One workout a week, a low key threshold and your weekend long ride is all you need to be prepared for the “real” training in the spring.
