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.
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.
Uphill segment
The segment challenge offers additional series ranking points to the top climbers over a defined section of the course. We go one better and honour the fastest athlete M/F of the 65k, 50k and 25k courses.
