Primiero Dolomiti Marathon 2026

The Primiero Dolomiti Marathon is a trail-running race series held in Primiero San Martino di Castrozza, within the Trentino Dolomites of northern Italy. Taking place in early July, it features multiple distances: 42K, 26K, 16K, 6.5K, and a Family Trail for those seeking a less demanding route. The primary 42K race holds significance as it serves as the Italian individual and club championship for short trail running. The event is organized by U.S. Primiero, based in Fiera di Primiero, and this marks its eleventh edition. The series caters to a range of participants beyond just marathoners: competitive trail runners can opt for the championship 42K, those preferring mid-distance can select the 26K or 16K, and families or beginners can participate in the 6.5K and Family Trail. Its classification as both running and trail aligns with a mountain race series centered in the Dolomites, distinct from a flat road marathon.
