The Austria Backyard Ultra in Thüringen, Vorarlberg begins at 9:00 a.m., with runners completing a 6.706 km loop each hour. The format follows the classic Backyard Ultra: complete the loop within the hour, return to the start line for the subsequent loop, and continue until unable to proceed. Late starts are not permitted; any runner missing an hourly departure is disqualified.
The course adheres to the official rules of the American original. The flat route offers mountain views instead of a point-to-point finish. Distances escalate rapidly: 7 laps exceed a marathon, 15 laps reach 100 km, and 24 laps cover 100 miles. The event continues until only one runner remains, meaning no standard award ceremony occurs; prizes and the DNF trophy are presented as each runner concludes their race. Bib pick-up takes place in front of the hall, and the race day includes music and commentary during the main daytime hours.
