Trail Running (Ultra Trail) is an outdoor recreation activity that is rapidly increasing in popularity in our country as well as all over the world. The tracks belonging to the trail running, which are formed within the framework of the International Trail Running Association (ITRA) rules, are scored according to their difficulty levels and height differences. The trail runs, which are held in the status of special competitions of the Turkish Athletics Federation in our country, are implemented by private sports organization companies.  There are no monetary prizes in the trail runs, which appeal to the participants from all professions who are devoted to trail running. The trail running, which has become an organization that appeals to middle-aged participants rather than active athletes due to its award system, has the characteristics of a recreational activity in which people from all professions participate.
