Donauinsel, Vienna, Austria
The Vienna Triathlon (also shown as Wien Triathlon or Triathlon Wien) is a two‑day multisport festival held on Donauinsel in Vienna on 12–13 September 2026, bringing together sprint and Olympic triathlon formats alongside aquathlon, aquabike and kids races. The programme combines branded races such as the XLAB Olympisch and CUPRA MAYER Sprint Distanz with family‑friendly events including the Tri Kagran Kids Aquathlon, creating a broad entry range for club, age‑group and junior athletes. The festival format includes a race village and on‑site expo across both days and is organised by P3Event Agentur in partnership with local sponsors and timing providers.
The event offers a dedicated race services programme with an official online registration window (closing 09 September 2026) and on‑site late entries until one hour before individual starts, and timing/results handled by established timing partners. The race village and expo operate 09:00–15:00 on both Saturday and Sunday, and the festival pages include athlete information, course maps, travel/parking guidance and competition rules. The event branding features title sponsors such as XLAB, CUPRA MAYER and Sun&Beauty and is presented as a confirmed fixture in the 2026 calendar.
