17. Mostiman Triathlon 2026

Mostiman is a mid-summer triathlon race series in Wallsee, Austria, starting on race morning with several formats centered on swimming, cycling, and running. The main Mostiman distance covers 1.5 km swimming, 38 km cycling, and 10 km running. The shorter Supaman version includes 0.75 km, 19 km, and 5 km. Aquabike and Bike-Run options are also available, allowing participation without completing all three disciplines. The series has been held for 16 years, organized by RATS Amstetten Sportunion. Its established Gaudiman, Supaman, and Mostiman categories remain, though the event now goes by the straightforward name MOSTIMAN, moving away from a previous sponsor name. The Mostiman Triathlon also serves as the venue for the Lower Austria state championships. The Olympic-distance race can qualify participants for European and World Championship events in Kitzbühel and Hamburg. Relay teams are accommodated via a relay exchange, facilitating partnerships for swimmers, cyclists, and runners who might otherwise compete individually.
