VO2 Max when running on snow/ice

Hi,

How is F945 actually calculating VO2 MAX? Why I'm asking is that during winter time I've been doing XC skiing, as well as running, but VO2 MAX has gone down few points and I seem to have trouble getting it back up. My theory also based on last winter is that it is because the runs are on snowy/icy roads or even pure ice on the sea with spiked shoes so it takes more effort to run at a given pace compared to clean tarmac and bouncy summer shoes. Would you agree with my theory?

It would be nice if one could define the surface where you run or would using e.g., trail run activity somewhat compensate this extra effort? Of course VO2 Max is just a number, but the constant "Unproductive" status during winter feels a bit dull.

    Your theory is correct.

    That wouldn't do much good unless the user were somehow able to assess the extra effort required. Defining just "snow" or "ice" or "mud" would not be enough.

    Garmin claims it does, but I remain skeptical, having vast experience with trail runs.

    True, one should need to input the estimated extra effort on these surfaces for it to make any sense.

    Thank you for you comments, maybe I'll just try the trail run activity in these scenarios and see how it behaves.

    Yeah, I'm not sure that it gives perfect compensation, but it probably gives a better result than just logging snow and ice as a road run.

    The other way would be to turn off VO2Max calculation in the Trail Run settings, and on better weather days when snow and ice has melted and conditions (if not temperatures) are more summer-like, keep your VO2 up to date logging it as a regular Run.

    I have disabled the 'Trail Run' vo2max calc, great for disabling vo2max for runs on fresh snow, ice, winter gear cuz negative 20°, hungover, etc.

    I just run bravely all winter, and when it gives me low VO2 max, I smile to myself, thinking, “I know something you don’t know,” and look forward to a burst of improvement showing up, come spring.
