O-SEE Challenge/O-SEE Classic/O-SEE Classic Team 2026

The O-SEE Challenge Reduced is a cross-triathlon in Olbersdorf, Saxony, taking place in mid-August as part of the O-SEE Challenge program. The Reduced race is for individual amateur and age-group athletes, while Reduced Team allows relay teams to compete in the same format. The course features a short off-road triathlon: a 0.75 km swim, a 26 km bike ride, and a 5 km run. Recent entries show the individual field with just over one hundred participants and the relay field slightly smaller. O-SEE SPORTS organizes the event via o-see-challenge.de. The overall event program also includes an XTERRA Youth Tour category for older juniors, which serves as a qualifier for the XTERRA Youth World Championship.
