RUNNABILITY
The runnability depends on the nature of the forest (density of trees/brushwood and undergrowth- bracken, brambles, nettles, etc.) but does not take account of marshes, stony ground etc. which are shown by separate symbols.
Runnability in forest is divided into 4 categories according to running speed. If speed through typically open runnable forest is, for example, 5min/km, the following ratios apply:
| min/km | ||
| open forest | 80-100% | 5 - 6m 15s/km |
| slow run | 60-80% | 6m 15s - 8m 20s |
| difficult to run | 20-60% | 8m 20s - 25 |
| fight | 0-20% | > 25 min/km |
White represents typically open runnable forest for the particular type of terrain. If no part of the forest is runnable then no white should appear on the map.
