Cardio Fitness Score replaced with estimate

[vjohn]

Last week my Cardio Fitness score was 43... Today I checked it out and it looks like its been deleted and I'm now seeing an "estimate". Any idea why my score seems to have suddenly been replaced by this estimate?

Hi @vjohn.  As I understand it, your cardio fitness score is shown as a range until you use GPS for runs. Not sure if it reverts from a single number to a range if use GPS a couple for runs a couple of times and then don't for a while, but that may be what is happening.  

Also, you only get a cardio fitness score if you are wearing an Alta HR, a Blaze or a Charge 2.  If you've got another model that you switch to occasionally that may cause the score to change or disappear.  

Regardless the cause, I think the next step to getting it back to a single number is to do some GPS runs over the next few days.  

Hope that helps.  Let us know!

@vjohn  I agree with @Baltoscott.  I have had too many knee surgeries to run much, but I managed to do a couple GPS connected runs to get a single number instead of a range.  After several months -- don't know exactly -- the score reverted back to the range.
