Hello @BjornS 

Thanks for posting about this!  I would recommend checking to make sure your activity is set to one of the activity types that have the trail route features.  Those are:

• Hikes


• Mountain Biking


• Trail Running


• Gravel Biking

See full details at this link

Let us know if that's helpful and thanks again for your post.

Hello Jane: Web Strava -> Using my Mac computer I have tried using the "gravel ride" descriptor you mention above (instead of "ride") for describing a ride and the Strava map still does not show the gravel roads vs. the paved roads. I have also tried changing the map type to dirt and that doesn't help to differentiate the paved roads from the gravel roads on my Strava map either.

Strava app -> If I designate the map type as "dirt" when I record a ride on my iPhone it does show both gravel and paved parts of the ride (gravel is dashed lines, paved road lines without dashes). Somehow Strava seems to handle the rides differently between iPhone and Mac computer. 

Do you have any idea why this is happening?

@DT2  In the web version the customized map is only displayed in the dashboard, but not in the activity view.
