Training Load for running activities is not visible

I have running and cycling activities and I am following training load.

I noticed that for cycling there is training load shown in activity itself (also exportable via browser developer tool under column activityTrainingLoad).

But there is no value for running activities - no value inside activity panel in web browser and also activityTrainingLoad field is empty.

I am using Forerunner 245 watch and hearth strap for running and Edge 530 with hearth strap for cycling.

But somehow exercise load is calculated, because inside status for 7-day Training Load (Reports -> All Activities -> Training Status), value for running is taken into account.

Where can I found this value - Web browser, Mobile app, json export, doesn't care, just want to know where to look for.
