As part of the UTMB World Series, it offers UTMB Performance Index points and showcases some of Europe's most pristine and challenging mountain terrain.

Other Distances at This Event

16.5K

Specific course details for the 16.5K distance have not been published by race organizers. Based on the technical terrain classification and the region's topography, runners should expect sustained rocky sections, root-laced forest trails, and potentially exposed passages where footing demands constant attention. The Carpathian environment means courses typically move through beech and spruce forests interspersed with alpine meadows.

20K

The course follows technical Carpathian trails marked by rocky sections that require careful footing. Runners move between forested valleys and exposed ridgeline sections, with the terrain favoring those comfortable on uneven, root-laced singletrack and loose rock. The region's trails reflect their working landscape origins rather than purpose-built race routes, meaning less predictable surfaces and grades throughout.

33K

The route traverses the technical terrain that gives the race its name, with rocky sections requiring precise foot placement and a willingness to use hands on steeper pitches. Long stretches of forest singletrack provide brief respite from the exposed ridges, though tree roots and embedded stones keep runners focused throughout. The Carpathian wilderness here is genuine—expect kilometers between aid stations and limited opportunity for external support once the race begins.

48K

The course traverses mixed Carpathian terrain, combining forest singletrack with exposed ridge sections and occasional rocky outcrops that require hands-on scrambling. Runners move through dense beech and spruce forests on trails that can be root-covered and technical, then emerge onto more open ridge lines where navigation becomes more exposed. The route showcases the diversity of Bucovina's mountain landscape, from shaded woodland passages to rocky high points with broader views of the surrounding peaks and valleys.

72K

The 72-kilometer route forms a demanding loop through the Rarău and Giumalău mountain ranges, characterized by sustained technical terrain and the geological complexity of the Eastern Carpathians. Runners encounter everything from narrow gorge passages to exposed ridgeline running, with the constant thread of ancient forest connecting the high points. The limestone substrate creates sharp, irregular footing in many sections, while centuries of rainfall have carved deeply into the softer stone. The course alternates between the intimacy of single-track forest trails and the exposure of alpine zones where weather can change within minutes. Several aid stations are positioned at traditional mountain passes and shepherds' huts, but stretches between support require runners to carry adequate supplies and navigation tools. The route's technical demands never relent, making this a race where experience with mixed mountain terrain matters as much as raw fitness.

114K

The 114K route explores the mountainous terrain of Bucovina, moving through sections of pine and beech forest interspersed with open ridgeline running that offers long views across the Carpathian range. Technical descents require focus, particularly as fatigue sets in during the latter stages. The course visits multiple peaks and traverses valleys where traditional Romanian villages provide cultural context to the physical challenge.
