KAILAS FUGA Dolomiti Extreme Trail is a June mountain trail-running event held in Forno di Zoldo, Veneto, northern Italy. The races are situated in Val di Zoldo, a Dolomite valley that has retained a wilder character than many well-known alpine areas, having avoided mass tourism. DXT began in 2013 and now provides seven options: the 103 km Ronda delle Cime, 72 km Euforia, 55 km Mitica, 35 km Celestiale, 22 km Emozione, 11 km Allegria, and Mini DXT for younger participants.
The longest route crosses the mountains surrounding Val di Zoldo, while the shorter races offer less demanding ways to experience the valley and Dolomite landscape. The event attracts a diverse group, from ultra runners competing in the 103 km course to families attending for the children's race and shorter trails. Recent years have seen over 3,000 runners from 69 countries participate. Atletica Zoldo, with local collaborators, organizes the event, supported by KAILAS FUGA as the title sponsor.
