7. O-SEE Backyard Ultra OBU 2027

Immerse yourself in the exhilarating world of endurance running at the O-SEE Backyard Ultra, an elimination race that challenges runners to push their limits like never before. This unique format sees all participants starting together every full hour on a scenic 6.7km loop around Olbersdorfer See.
Each lap offers a mix of challenging terrain with 62 metres of elevation gain and serene stretches in the shade, providing stunning views over the lake to the Zittau Mountains. Runners have exactly one hour per lap to complete their circuit before resting until the next start time an hour later. The race continues indefinitely, eliminating runners who fail to reach the starting line on time or finish within the allotted period.
The final victor is not determined by speed alone but rather by endurance and strategic pacing. This event rewards those with a longer breath in both senses of the phrase—literally as they push their physical limits and metaphorically as they outlast competitors over days of relentless competition.
Beyond its competitive edge, O-SEE Backyard Ultra offers exceptional amenities to support runners through every stage of this grueling challenge. Enjoy freshly prepared vegetarian and vegan meals alongside a wide selection of refreshments throughout the event. The race also provides free camping facilities directly adjacent to the start/finish area for convenient rest between laps.
For those seeking comfort during their stay, several well-located hotels such as Haus am See, Dresdner Hof, and Schloßhotel Althörnitz offer nearby accommodations. Campers can opt for a more rugged experience at SeeCamping Zittauer Gebirge if they prefer to travel with a vehicle.
Beyond the race itself, participants are encouraged to explore the surrounding region's natural beauty and cultural attractions within easy reach of Olbersdorfer See. With breathtaking landscapes and just minutes from both Czech Republic and Poland borders, there’s ample opportunity for adventure beyond the track.
In addition to individual accolades, teams can vie for recognition in a special team competition where three runners with identical team names compete collectively based on cumulative lap count. A separate "Last Woman Standing" category also celebrates female athletes who demonstrate exceptional endurance throughout the event.
Whether you're aiming for victory or simply embracing an unparalleled running experience, O-SEE Backyard Ultra promises to be a memorable chapter in your athletic journey. Join us from July 8th, 2028, and prepare to go hard—or go home!
