Fitness Age

I always wondered how this fitness age is calculated. I’m 48, but my Race S (and the app) says my fitness age is 29 - and gives me very optimistic race estimations.
Garmin on the other hand (yeah, those guys again) says 39 and the race estimations are way more realistic…

As both have about the same estimation of my VO2max, I wonder what makes the difference…

@2b2bff Well on my V1 my fitness age was 26 on the V2 it is 38 I’m 59.

I don’t take any notice of it to be fair and really don’t understand the obsession with these made up metrics. But each to their own.

I’m 29 and my watch tells me I’m 30-32. It hurts.

I train 6-8 hours per week. Maybe that’s bad for me

Me for Suunto : fitness age 36 and VO2max 46 and I’m 66 years old. For Garmin 55 years and 49 at my best last summer.

It’s not an obsession, but I think the different race estimations are coupled with that age. Therefore I want to understand it. It’s nothing I’m optimizing on…

@2b2bff It should not be coupled with age it it is probably coupled with Vo2max and threshold pace(?), everything else is probably just automated “Riegel formula”.

@aiv4r that’s what I’m trying to figure out.

Suunto:

fitness age: 29
VO2max: 52.4
10k estimation: 41’46

Garmin:

fitness age: 39
VO2max: 53
10k estimation: 44:06

Me:

Age: 48
10k PB 45:38
last race result: almost 10k in 45:55

That’s why I think that the race estimation is very optimistic on my Race S, possibly because or connected to that fitness age…
