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
