Fitness Age

I don't think there's a way to see it on the watch.  I just go into "Training Status" in Garmin Connect, then VO2 Max and you'll see it at the bottom.

Yeah or directly under "Health Stats"
Now it's 9 years max less than your actual age versus "no limit" previously !

Yeah oddly some cheap Forerunner watches (and the Venu too I think) like the FR55 show it directly on the watch.

I think that's probably a good move. At one point it was claiming I had a fitness age of 21... quite a stretch.

Well, that may be true for your particular age, but I'm 72 years old and my fitness age is shown as 58.  If the math I do in my head is still correct, that's a 14 year delta - 5 years more than the "9 years max" you cite.

HTH

Yes. 65 and Fitness age of 55. Vo2max used to equate that value with a 25 year old. Bruised my ego a bit. Lol

Same here, I am 65, fitness age 55

72 with fitness age of 58.
Can I ask - is it possible to get VO2 Max and fitness age after using walk or hike app i.e. not just when you use the run app?

Only run or trail run, and cycling if you have a power meter. I purchased a PowerPod Lite for my road bike and a Garmin Speed Sensor so I could get vo2max on my bike. Cheapest option/attaches to bars, and works pretty well.

I do not know but the manual states running or biking. So I would guess not.
