TDM Trail dos Morcegos is a September trail running series held in Ponta Delgada on São Miguel in the Azores. It includes a 53.2K ultra, a 34.4K trail race, an 18.9K race, a walking event, and children's races, catering to experienced mountain runners, beginners, families, and children.
The routes utilize the island's terrain, featuring cliffs, viewpoints, coastal paths, forest sections, and technically challenging stretches. Organized by Morcegos Trail Clube, the event marks its 10th edition and attracts participants from Portugal and other countries. The inclusion of a non-competitive walk and children's races contributes to a weekend atmosphere rather than a singular competitive event.
