5. Biber Backyard Ultra

The Biber Backyard Ultra is a unique ultra-running event in Simmerath/Lammersdorf scheduled for June 13, 2026. Participants run a 6.7-kilometer loop every hour with varying elevation gains until only one runner remains. The course passes through forest and field paths as well as trails with a challenging incline. The event is characterized by its special Ultra-Backyard format, where each loop must be completed within one hour. The event offers a family-friendly atmosphere and challenges endurance and tactics alike.

Registration traditionally opens on December 6 at 00:01. The course is divided into a day and a night section. There is no lap time measurement; only the number of completed laps is counted. Start announcements are made 3, 2, and 1 minute before each lap. Personal support and aids during the lap are not allowed. The event has a family atmosphere with sponsorship from outdoor manufacturer OMM. The course is split into day and night segments, with 110 meters of elevation during the day and 60 meters at night. Catering is available at the start/finish area, along with showers, sanitary facilities, accommodation options, and community events on site.
