Over on Facebook, Zach bagnall (LEL rider) mentioned this software he has written.
https://routecheck.cc/?fref=gc#rwgps/2927186 should link to LEL S3 route. clicking on the POI lets you show various POIs that might be of interest. Might be useful prior to a ride to check on escape routes, etc. If you click on Map and deselect starve, the map becomes much clearer!
