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

Navigation & Turn-By-Turn Directions
You are required to have on your person our custom cue sheets provided below; turn-by-turn GPX/TCX instructions on a GPS bike computer are highly recommended. The course will ONLY be signed at two-tracks, snowmobile trails, etc. where some added clarity might be needed. Signs may fall down, get stolen or be reversed out of spite so it’s best to trust GPS files and cue sheets. If you want turn-by-turn directions, your best bet is a Garmin Edge, Wahoo Element or other bike computer that provides that from a TCX or FIT file.
