Transylvania 100

Transylvania 100 is a mountain running event offering five different races, from a half marathon to a 100 km ultra-marathon, held in the Bucegi Mountains. The routes cross narrow trails, ancient forests, mountain plateaus, and exposed ridges, with numerous ascents and descents, all starting and ending at Bran Castle, in the shadow of the legendary Dracula. The event is recognized as an UTMB Index race and promotes values such as respect, solidarity, and self-sufficiency in mountain running. Participants must have prior experience in mountain running for the longer races, and all finishers within the time limits receive a special souvenir.

Technical SportHG shirts available until May 1, 2026, later replaced with neckwarmers. Participation limits and prior experience are mandatory for races over 20 km. All races are solo, with strict self-sufficiency rules between control points. The event includes races for different experience levels, with prizes for winners and medals for all finishers. Participation requires trail running experience, and registrations are made online, with limited spots.
