Backyard Ultra Rotterdam 2026

Backyard Ultra Rotterdam is a race held in May in Rotterdam, located in the Dutch province of Zuid-Holland. It follows a backyard ultra format, consisting of repeated laps. One lap is designated as 7 km, and completing all 24 rounds would cover 161 km. Participants have the option to finish after one lap or continue for multiple rounds, meaning the event can range from a 7 km run to an ultra-distance challenge. The provided information specifies the location and distance structure but offers limited details on the precise route, participants, or traditions. Therefore, the event is best understood as a lap race based in Rotterdam, where endurance is built through repetition rather than a single, extended point-to-point course.
