Trail Monster Running is a group of trail runners based in Southern Maine who enjoy sharing our passion for the outdoors with others. We host regular group runs, Fat Ass events and races throughout the year to bring together members of the trail running community. From 5k cross country races to 100 milers, Trail Monsters run them all. Anyone with a SERIOUS interest in trail running is welcome to join us for any of our group runs, we welcome trail runners of all abilities, but becoming a Trail Monster takes something extra. Trail Monsters are actively engaged in the trail running community by volunteering at races, participating in trail maintenance, hosting group runs and consistently demonstrating their love of trail running.
