5. TCW Backyard Ultra

The TCW Backyard Ultra in Wölfersheim is a unique running event focused on camaraderie and endurance. Runners start on the hour and must complete a 6.706 km loop within one hour.

Personal assistance on the course is not permitted, but participants may support one another. Trekking poles and artificial aids are prohibited. Participation is limited, so early registration is required; the event follows the Backyard Ultra format and regularly attracts over 400 applicants.
