I’ve been doing more-or-less this for some time now, but this will be a lot more slick….
Ive been downloading the trials as gpx’s from trail forks, loading to the Garmin (810) then using the app on the phone to browse the trails figure out what I want to ride and bringing it up on the Garmin to follow down.
Admittedly this takes more planning, having to download the trails first, then load them to the Garmin, but has been working well for me.
the only issue is the download limit for the GPX’s something like golfy takes days to download the trails, so this might be worth getting a new fangled x20 Garmin……
Im a big fan of trail forks, its loads better than Strava! the pink bike guys have done a great job of it 🙂
