The best thing about trail running in the Guadarrama Mountains is that there are incredible options for all skill levels. However, trail running is inherently a physically demanding activity, so even the easiest routes require a decent level of fitness. The beginner routes are simple and relatively flat runs, while the more advanced routes are longer, include more inclines and more complex terrain. You will be running through varied terrain for approximately 3-4 hours. Your guide will make sure that the running pace is adapted to your individual capabilities.
