Calculating walking time is a hotly contested topic in hiking circles. Everyone has their own estimate according to their level.
On this website, walking times are calculated according to the following rules :
– 15 minutes for 1 km flat / 100 meters of positive elevation / 200 meters of negative elevation.
For an uphill hike, 300 positive and 600 negative meters per hour.
The surface of the course influences the walking time. A wide, flat path and a rough uphill or downhill path do not walk at the same pace.
