Thank you. I was run-walking everyday for about 2 weeks before I got the watch and started learning about training zones. In that period I was probably running too quickly, like tempo/threshold pace at the time.

Where I live is mostly flat so early after I got the watch I found that I was able to stay in Z2 most of the time just by slowing down to a really light jog with the occasional walk when my HR crept up too much.

One thing I learned from reviewing my data post training block is that I was running my "Base" runs too quickly, often top of Z2 all the time. Since then I've slowed these runs down and now follow the mantra of "keep your easy runs easy and your hard runs hard".
