XTERRA O-SEE 50k Ultra Trail & Team DUO
Not only will the more than 2,000 meters of altitude take your breath away on the (originally) hardest and longest kilometers of the Zittau Mountains, the spectacular views will also leave you breathless from time to time.
In 2026, XTERRA O-SEE Ultra Trail will also host the XTERRA European Trail Run Championship, contested exclusively over the 25 km and 50 km distances. These championship races will award the top finishers in all age-group categories and offer qualification slots to the 2027 XTERRA Trail Run World Championship, adding an extra layer of meaning and opportunity to every step of the course.

The XTERRA O-SEE 50k course is part of the global XTERRA Trail Run World Series, and will be counted as a qualifier for the XTERRA Trail Run World Championship. Slots will be awarded to the top finishing individual runners of each age-group.
