When you are using the 80/20 training plans how do you setup your heart rate zones especially for the speed work? My understanding is that 80/20 uses a 7 zone system for heart rate and I would assume that MAF would be Zone 2. How do you determine the other zones?
Nicole's reply: Hi Frank, I don't know if you have got the book 80/20 training, but that explains how to set up your zones. Link to book. If not, have a look at 80/20 resources which has lots of great info and explanations on setting up your zones.
