The 3 Dias Trail Trebol takes runners onto steep trails above Vallehermoso on La Gomera, one of Spain’s Canary Islands. This mid-July trail running event offers three main distances: MINI at approximately 13 km, MEDIA at 23 km, and MARATHON at 40.2 km. Each distance involves significant climbing, with about 800 m of ascent for the short race, 1,500 m for the middle race, and 3,180 m for the marathon.
The course features mountain and nature trails, avoiding flat road sections. It is suited for runners seeking climbing, technical terrain, and island landscapes. The marathon distance is listed with a UTMB Index, providing qualifying results for trail runners or a way to compare mountain race performances. The event caters to a broad spectrum of participants, from those opting for the shorter MINI route to seasoned trail runners tackling the full mountain course.
