Kalk Trophy | Saturday, 8 August 2026

The Kalk Trophy is a one‑day mountain sport festival held in Molln, Austria, organised by Naturfreunde Steinbach‑Grünburg together with Bernegger GmbH. The 2026 edition (Kalk Trophy) is scheduled for Saturday 8 August and finishes at the Pfaffenboden‑Steinbruch, an imposing local quarry that forms the event's signature finish area. The programme brings together mountain bike and uphill running disciplines under a single brand and attracts regional competitors and hobby athletes alike.

A headline feature of the event is the Tunnel‑Berglauf, a steep uphill run that includes an extended tunnel section; the Tunnel‑Berglauf course is listed as 5.2 km with approximately 680 m of ascent and about 3.5 km run through the Elfi‑Tunnel. The day also comprises several mountain‑bike races (including an MTB‑Bergrennen, an MTB‑Tunnel‑Race and hobby/eBike categories) and a Nordic walking class, and the Kalk Trophy is part of the Int. Österreichischen Berglaufcup. Practical details such as precise start waves, full course maps and registration inclusions are published on the event website and in the athlete information documents nearer the event date.
