How to turn off the 'Track Detection' feature?

Hi all,

After my track sessions I usually run barefoot at the football pitch but while all my previous Garmins detected it well the 970 insists that I am running at the track messing up the distance and, consequently, the pace.

Is there any way to avoid this happening?

I always select 'Track Run' for the track sessions and either 'Run' or 'Trail Run' for these barefoot cool down sessions on grass.

Thank you all in advance!
