DIY or modify an existing route
If you need to create your own route from scratch, or combine multiple activities together here are a couple options I've found helpful:
- Email me at daniel@topofirma.com if you get stuck. I'm happy to help!
- GPX Studio at https://gpx.studio/ is an excellent, free tool for creating and modifying gpx files. (Topofirma is not affiliated with GPX Studio but does support it through donations.)
- Strava -> build your own route, then export the .gpx
- Garmin -> create a course, then export the .gpx
You can then drag and drop the downloaded .GPX file into Sculpture Studio
