I often group several trails together and give the resulting trail a "combined name" because:

  • Many trails are short, or may have name changes along their length
  • GPS receivers have a limited number of tracks that they can display
  • Simplifies loading trails into a GPS & the associated documentation

I've also grouped the resulting tracks into zones to simplify maps and trail listings

Open Street Map

It is a routable cycle map of Colorado including parts of neighboring states.

Simply copy the CO_OSM_Cycle.img file to Garmin folder on your GPS.

This CO_OSM_Generic.img file is similar to above, but includes more Open Street Map features.

Open Street Map routing depends on the multi-use paths etc being "designated" as a bicycle path.

(Sometimes people editing the map switch them back to footpaths...)
