Based on what? That's not too outlandish an estimate, actually. The Uth-Sorensen-Pedersen estimation would put mine at 61.5 or so, though it's been a while since I took my resting HR. So if that's what the Garmin uses to estimate your VO2, that's an easy-to-believe number if your HRrest and HRmax are similar to mine. In well-trained males (i.e. you and me), it's a surprisingly good estimate. Usually within 4.5%. The question with VO2 is whether having a number is any real use to most people.
