  • No longer available on Ride with GPX to make sure there are not multiple copies of the route floating around. Sorry.
 

General Navigation

  • You are required to have our custom cue sheets provided above; Following a GPX/TCX file on a GPS bike computer is highly recommended. The course will ONLY be signed at two-tracks, snowmobile trails, etc. where some added clarity might be needed.
  • You may need to download the file to your desktop/laptop, connect your phone via USB, and then move GPX or TCX to bike computer (e.g., into New Files folder in Garmin).
  • You may need to split the route into two sections for your bike computer to handle the file.
  • Note: GPX is a basic GPS track, compatible with most GPS devices. TCX is a GPS track with turn-by-turn directions, compatible with newer GPS devices. FIT is the best format for turn-by-turn directions on modern Garmin Edge Devices.

Turn-By-Turn Directions

Standard Strava .gpx or .tcx route files simply contain a “breadcrumb” string of coordinates. They do not contain turn-by-turn directions. To get the commands to register on a cycling computer (like a Garmin or Wahoo) or navigation app, follow these steps:

  1. Export the Route: Download your route file from Strava in the GPX format.
  2. Import into a Navigation Planner: Upload that .gpx file to a route-building platform that supports turn generation, such as Ride with GPS or Komoot.
  3. Generate Cues: These platforms will automatically convert the raw line into an interactive map that generates turn-by-turn cue sheets and audio notifications.
  4. Export as TCX/FIT: Export the new route from that platform to your Garmin Edge, Wahoo Element or other navigation app using the .tcx or .fit file format, as the .gpx format does not natively support turn notifications.
