XTERRA
XTERRA Trail Run World Series
Nationwide and international. O-SEE Ultra Trail is part of the global XTERRA Trail Run World Series – as the only event in Germany.
Compete individually, regionally or globally in the XTERRA Trail Run rankings, or push to the front of the pack in your age group to qualify for a place on the starting line at the annual and invite-only XTERRA Trail Run World Championship.
See the XTERRA Trail Run World Series page for information regarding the rankings, qualification rules and criteria.
Team DUO
Misery always loves company, so why not suffer the endurance challenge with a friend (Men, Women or Mix) rather than solo. DUO teams must start and finish at the same time to be eligible. No individual scoring possible.
Distances & categories
The XTERRA O-SEE Ultra Trail includes both half-marathon (O-SEE 25k) and full-marathon (O-SEE 50k) races, with individual and team DUO categories available.
