The user-defined trails can be modified according to your preferences. You can change name, distance, and type (trail or flat/paved road). Changing the value of ”include” from ”no” to ”yes” will make the trail enabled in the trail selection menus. The profile and terrain factors for the user-defined trails can be modified in the table dedicated to these factors below.
profile and terrain factors
Tabulated values of profile and terrain factors for all defined distances/trails. The default terrain factors are 0% for paved roads and 20% for trails. The trail profile factors are calculated from the elevation profiles for existing trails. For the generic trails default values are used (0% for paved roads and 3% for trails). If you change the values, the new values will be used in the next calculation.
The time estimations are calculated using the Pete Riegel formula:
currently used distance factor: df = 6.0 %
default distance factor (can be modified): df = 6.0 %
