First, congrats on making it 1 mile non-stop.
Second, I wouldn't worry much about training status until until you have a few more runs where you are able to run 10 minutes or more at a steady state. The system really needs 10 minutes or so to even make a vo2max judgement. Over time the watch will adapt and you'll get better information out of it. That said, I still get unproductive from time to time even when I feel like I'm getting faster. All that is really telling you is to pay attention to recovery, sleep, nutrition, and the 100 other little things that make a difference in how your body absorbs the load of adding physical stress via training.
I’m not convinced it’s accurate. I have just run the same 5k route that I did yesterday. Exact same average and max hr. today 30 secs faster. Yesterday I remained above the line for the whole run ending +3, today I’m below for last half ending -5. I can’t see anything in the data to explain why. Both were run at an easy pace.
I am not sure whether only hr:pace ratios are considered to define your PC. I know it is said by Firstbeat, too, but I have an impression that maybe HRV data are considered, too. I cant prove it, but without HRV I cant explain either the PC stats provided by my watch
Thanks, I don’t know much about hrv, but have just seen what you have suggested confirmed on Garmins website. I’ll look into it, this must be what’s contributed to the odd results
