A calculator for the length, duration and average speed of multi-day tours, for walking and biking. This calculator assumes an even terrain, so that a constant speed can be kept. A normal hiking speed is 4 km/h. At mountain hikes, the speed varies significantly and is lower. How many hours per day you want to walk depends on how much sleep you need, maybe time to find an accommodation, for eating and pauses and often you may want to visit something. 8 hours of pure movement time are very much.
