VO2max and performance acting strangely

I just did my first ever recovery run. In fact it was the first run I've done where I targeted low aerobic activity, I've owned a Garmin for 4 months.

Here's the weird thing, while doing my recovery run (which might still have been a little fast as Fenix 6 tells me I targeted base not recovery) my performance came up as -5 fair. That's the lowest I've ever seen it, it's nearly always positive. Then my VO2max dropped when I finished and my status changed from "Productive" to "Overreaching". It's nearly always been "Productive" and has never been "Overreaching" before.

Why did this slow run have this effect? I know it's a bit precious but I'd almost made the superior VO2max bracket and one slow run brought it down.

What gives?

  • really  strange, because i notice the total opposite. Since i am working out for marathon and doing quite a lot slow (long)runs with low effort my  VO2max  is rising and rising. Before it was about 60,  yesterday i reached 65. Highest i ever reached.

    What does your pulse say and are you using a strap? Is it constant and in the zone you are expecting, or "flipping around"/high?

    (Because i focus my  training on HR Zones i just run with a HR Strap, because it is and always be just more accurate)
