In a recent post of an aerobic-intensity profile called Ebb and Flow, I received a question from ICA member Tracey about the Zone 3 level of intensity of the profile.
Hi Jennifer, I have heard and read that you typically want to avoid Zone 3. That most people spend too much time in that grey zone and that the easy should be easy and the hard hard. So typically I have read and understood that 80% of our training should be in Zone 1/2, 10% at threshold (Zone 4), and 10% doing HIIT or anaerobic training (Zone 5, 6, and 7, assuming a Zone 7 system). Just wondering if this has changed? Thanks for your time.
This question tells me that Tracey has done some research on cycling training techniques! Good for you, Tracey.
It’s true that Zone 3, known as “tempo” training in most cycling zone methodologies, used to be called the “dead zone” or “no-man’s land” by some cycling coaches. But it’s important to look at the context of that description and who it applies to.
