Notes:

  • "Length" is measured along the most direct course possible between
    controls, i.e. straight lines, not crossing impassable obstacles but
    otherwise direct.
  • "Climb" refers to the total elevation gain as a percentage of the
    course length, following a reasonable route.
    For instance, 4% climb on a 6 km course would be 240 m elevation gain.
