3 Días Trail Ibiza is a three-day trail running series on Ibiza in Spain’s Balearic Islands, usually held in late November. It is built around three stages on the island, with race options from 10 to 42 kilometers, allowing runners to choose from a shorter trail outing to a marathon-length challenge.
The event is on the Balearic Athletics Federation calendar and runs under the 3 Días Trail Ibiza – Ultra Ibiza name. Its aim is to race for three days, see more of Ibiza than the beach version, and pass through parts of the island tied to its landscape, history, and local culture.
