Researchers from the department of Physical Geography and Regional Geographical Analysis at the University of Seville have developed a new system to estimate the time that it takes to do a walk in the countryside. It is an algorithm that takes into account length and gradient as the main variables when establishing how long a walk takes. After applying their method on routes all across Spain, they are convinced that their formula provides a better approximation of the time that will be taken by an average hiker than other systems currently in use.
