Hi,
From what I've read you are using Mapbox as the company to provide mapping and they are using OSM for surface types. I would like to ask you how often do you update your surface types in Strava Routes?
I'm asking because I wonder if it's worth editing surfaces in my neighborhood so it's visible for everyone in Strava Routes.
Sometimes it's quite annyoing when drawing a route, riding it and after that someones says that you could go nicer path somewhere because it is smooth tarmac and on the Routes it was marked as dirt..
Cheers,
Filip
