I ran a marathon a few months back. I can run 5k in 25mins and I'm set to do a half marathon in 2 hours. Yet me cardio fitness score tells me I'm at the bottom of average. My resting heart rate is 57 which I thought was pretty good. I have a surge so do GPS tracker runs all the time, can anyone tell me how on Earth my score could be so low???

Hi, @Paddymaree, "cardio fitness" was a feature brought in with Charge 2 and the Blaze was later updated also to include this feature.  However, as @shipo mentions, this was not added to the Surge, and if you have been mainly wearing your Surge while running that is why the score has not updated to reflect your performance.

 

If you still have the Charge 2, if you occasionally (once a month, say) run using the "connected GPS" feature on the Charge 2, you should find that your score updates.  (A run of at least 10 minutes, preferably on flat ground, using connected GPS is required for the cardio fitness score to update.)

 

The Surge has not been discontinued, so I suppose it is possible that Fitbit will add cardio fitness to its features (I don't think there is any reason why it culdn't be added), but as most of the Surge's features have been superseded by the Ionic, I am not at all confident that this will happen.

I'm curious, I wore a Surge pretty much every day between April of 2015 and yesterday, during which time I ran somewhere in the neighborhood of 5,000 miles, and I never once had the ability to check my Cardio Fitness Score.  At midnight last night I switched over to my new Ionic and presto-chango, I now have a Cardio Fitness Score.

 

My understanding is the Surge never had this capability.

Interesting. I first started with a charge 2. Perhaps the Fitbit app has gotten confused and that's why my score has not gotten any higher. I bought my surge only a few months before the ionic came out 😞

Thank you for this information. Although I am confused why surge with a built in GPS doesn't have this feature, it's good to know that I wasn't doing something wrong or the feature isn't necessarily broken.

The Surge was basically the oldest tracker in the Fitbit lineup, oldest chronologically as well as technologically.  I rather doubt the Surge had the ability to do the Cardo Fitness Score calculations.
