Rad, this is not a noob question, it’s probably one of the top 5 questions we get on the Forums.
First, you did the test exactly right and I confirm your zones.
Second, while the division between low and moderate (Zone 2 and X) in the 80/20 system is empirical, the division between Zone 1 and 2 is, and even the fact that we split “easy” intensity between Zone 1 and 2 is not. It’s a best-guess by Matt and I. In other words, easy is easy. We created Zone 1 to force athletes to slow down for for recovery intervals.
The point here is that if the workout calls for Zone 1, you can stay in Zone 2 and are still 100% in the 80/20 system.
For you, that means unlimited time at a 10:08 pace. That’s certainly not fast, but should not be baby steps for anyone. 10:08 is real running. Therefore, just stay at 10:08 for Zone 1 or Zone 2.
If 10:08 is still baby steps, I’m surprised, but if it is, then use HR for now. In 3 months your Pace threshold will be 8:15 and your Zone 2 will be 9:29 and this won’t be an issue. But, for now, using HR is great.
