Vull wat Manns Loop is a muddy cross-country and obstacle-course race in Logabirum, held annually since 2010. The adult route covers 5 km through a gravel pit, featuring mud, dirt, water, and built-in obstacles. It takes place over two days in late August. The main 5 km option is run without timekeeping, making it accessible for participants not focused on achieving a specific time.
The race attracts a diverse group of participants: competitive runners, recreational athletes, and those who do not train consistently. Children have their own shorter course on Saturday, divided by age group instead of joining the adult loop. The event has seen consistent growth, with over 3,000 participants across both days in a recent year. Accounts from the race emphasize its messy nature as a key reason for its popularity.
