The event "O-SEE Backyard Ultra 11.-12. Juli 2026" is a Last‑Man‑Standing running race held on a loop around the Olbersdorfer See with start and finish at the Westparkstadion Zittau/Pethau. The format follows the Backyard‑Ultra rules: all runners start together on the hour and must complete each 6.7056 km lap within 60 minutes (BY‑Kids: 10 minutes). The organiser, O‑SEE Sports e.V., presents the race as part of the Backyard‑Ultra calendar and highlights direct qualification implications for the German championship.
The event combines competitive racing with a festival atmosphere, offering on‑site camping, catering and basic stadium facilities close to the start area. Participants receive a high‑quality 3D medal showing laps completed and lap times are recorded and published via MyRaceResult. The race is promoted as family‑friendly, spectator‑friendly and suitable for multi‑day competition depending on how long competitors remain in the event.
