6.6 Recommended symbols

6.6.2 Discipline-specific symbols

The following symbols are introduced for mountain bike orienteering maps.

Road and track classification

Mountain bike orienteering requires two classifications for tracks and paths: a. speed (or "riding") and b. width. Three classes of speed and two classes of width, given in all six combinations, is optimal.
Note: dimensions are specified in mm at the scale of 1:15 000.
All drawings are at 1:7 500 for clarity only.

"Riding" classification

Three levels of classification is proposed: EASY, SLOW, DIFFICULT.

Width classification

Two levels of width is proposed:

MORE THAN 1.5 m WIDE (termed "TRACK")

vehicle track can be used by four wheeled vehicles, cars, tractors, forestry always possible to pass or cross other bikers

LESS THAN 1.5 m WIDE (termed "PATH")

too narrow for a four wheeled vehicle hiking path

811 Track: easy riding

A track with stabilised surface at least 1.5m wide. Forest road or well maintained track with no obstacles.
Colour: black.

812 Path: easy riding

Well maintained path narrower than 1.5m. Smooth, clean path with no erosion or obstacles.
Colour: black.

813 Track: slow riding

A track at least 1.5m wide. Infrequently used, with ruts, grassy, wet, muddy or sandy. Possibility of rocky surfaces. Pedalling is more difficult, riding is slowed.
Colour: black.

814 Path: slow riding

Path narrower than 1.5m, through difficult terrain, with rocky or banked surface. Other characteristics as in 813.
Colour: black.

815 Track: difficult to ride

Rarely used track at least 1.5m wide, with obstacles such as roots or rocky steps. Many obstacles, stones, rocks, erosion, mud, land slides or sand. Very slow or impossible riding. Could necessitate to carry bike.
Colour: black.

816 Path: difficult to ride

Path narrower than 1.5m, through very difficult terrain. Mountain paths with many obstacles. Other characteristics as in 815.
Colour: black.
