The routes of the 4Days Marches are never exactly 30, 40 or 50 kilometres. Various factors play a role in determining the routes. There are logistical factors like access to the roads and accessibility for security services, for example, but also aesthetic considerations like whether it is a pleasant route with sufficient variation between nature and residential areas, et cetera. The fact that the total distance to be covered may deviate slightly has already been taken into account in the daily time limit for the walk, which is long enough that every participant should be able to complete the route within the set time.
