100-Mile Route & Course Files

Sometimes it’s not the finish line that matters. It’s the struggle that went before.  – author unknown

100-Mile Coast Loop Key Stats

  • Route: Ludington-Manistee Natl Forest loop

General Navigation & Turn-By-Turn Directions

  • You are required to have our custom cue sheets provided below; 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.
  • If you want turn-by-turn directions, your best bet is a Garmin Edge, Wahoo Element or other bike computer with a TCX or FIT file.
  • 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).
  • 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 (available via Ride with GPS).
