The fitness score of a run activity is much lower than a cycling activity.

Mt. Kenya

I do both running activity and cycling activity. Sometimes my main activity is cycling such as in 2022, and sometimes my main activity is running such as in 2023 and 2024, however, the fitness score have big difference, which confused me.

Let me select two activities as example:

(1) Cycling:

Training impulse in fitness page is 163 (sum of two activities in one day)

AVG heart rate (143bpm@54min + 119bpm@70min)

(2) Running

Training impulse in fitness page is 163

AVG heart rate 152@94min

The physical intensity of The Running activity(2) is a little higher than the two cycling activities(1), however, the fitness score of running activity is less than 25% of cycling activity.

So when I mainly do cycling activity, the fitness level is easily reach 30+, and when I mainly do running activity, the fitness level is less than 10 even if I train hard.

Could support team check the algorithm and make the fitness score similar between a cycling activity and a running activity with similar physical intensity?

Thank you!

Hello @lester98 

Thanks for posting about this.  There can be a lot of different factors that influence fitness scores.  For example I notice on your rides you are recording power data and heart rate, while runs just have heart rate data.  

I've escalated this to a support ticket, so someone from our support Team can have a close look at your activities and settings and provided more information.  Thanks.
