The Garmin Vo2 max estimate is supposed to be pretty accurate too, but mines is wildly off.
It also has race pace estimates for 5k, 10k, half mile etc and those are wildly off too. I think it bases these off Vo2 max, so its unsurprising. It thinks I can do a 42min 10k, that is just never happening.
