How many times do I need to use GPS Run to get an exact Cardio Fitness Score?

[rossinopecorino]

I’ve been using the GPS tracked Run function on my Inspire HR for the last 3 weeks, and have completed 12 or more runs of 30 minutes+ on flat terrain. My Cardio Fitness Score is however still showing as a range and hasn’t changed at all (it’s Very Good-Excellent, so no complaints!). When can I expect it to narrow down to a specific score/number? Or is there anything I should be doing differently?

@rossinopecorino It's great to have you here! Sorry for the delay in my reply.

Let me help you with your Cardio Fitness Score. There isn't a stated minimum amount of runs you need to do before you get a better or more specific reading. I suggest you try running for a shorter period (15 to 20 minutes) and see (after some runs) how the data is interpreted by the app.

Let me know how it goes.

Did you ever resolve this? I’m having the same issue
