Scott,
Thank you. It looks like everything lines up with what I pulled from the book and here in the Forum. Your point about recovery is well taken. Given the main four zones, I added below Z1 as “Recovery” and above Z4 as “Capacity” just so there was a “bucket” to capture the data in for long term tracking.
Thanks again and recommending Uphill Athlete to all my like-minded friends.
Thanks again.
Michael
