- PR, 10-20 sec/mile faster than my previous training runs (about 10K). A 54-55 minute run.
- "Unproductive" (orange) status
- VO2max down 1 unit from last one, measured last week (which in turn had increased 2 units from the week prior)
- Lactate threshold improved 15 sec/mile and 2BPM two days ago on a different, hillier course (and it felt like I was getting stronger, it was a good run)
- Performance condition started at 0 and dropped to (-) 4 by end of the run
- Average HR 89% of peak HR
- Some aerobic activity charted by Garmin
I was pretty much beat at the end of the run. It's always hard to say that one couldn't have run it harder, maybe I could have, but I was pretty close to being empty when I was done.
I wonder if the metrics like "lower VO2 max", "lower Performance Condition than usual", "Higher than usual HR for running velocity (maybe?)" pushed Garmin's algorithms into labelling it "Orange - Unproductive", and the only reason I got a PR *despite" the poor metrics/implied poor physiology today was the good/competitive attitude I felt, a "non-measurable" metric?
Thanks for any thoughts/help understanding!
