Have a 6S Pro, updated to version 9.
I only record cycling activities (with a few kayak activities thrown in) but don't have a power meter, so never expected to see a VO2 Max calc. But I actually have one that shows up in Performance Stats - how's that possible?
I recently started using a Polar OH1+ for heartrate, but have been using that for weeks and just saw the VO2 Max reading for the first time today.
