Biber Backyard Ultra

The Biber Backyard Ultra is a unique endurance running event featuring a 6.7-kilometer loop course with varying elevation, held in Simmerath, Germany. Participants run as many laps as possible within a designated time frame, with each lap starting every hour. The event includes both day and night courses, requiring runners to carry headlamps after dark.

Basic refreshments are provided at the start/finish area, but participants must manage their own supplies during the race. The event emphasizes self-sufficiency, respect for nature, and personal responsibility for safety. The last runner to complete a lap within the time limit is declared the winner.
