The Seizer Herbstlauf is a small autumn cross-country race in Seiz, part of Kammern im Liesingtal in Styria, Austria. It is expected around the end of September, with the race base at the Freiwillige Feuerwehr Seiz on St. Ulrichsweg. The programme includes a 7.2 km run and a 3.18 km Nordic walk, so it suits runners and walkers rather than only competitive racers.
All races start and finish at the fire station, which makes the event simple to follow for spectators and easy to manage for participants. The race day is paired with the Strohfest, a straw festival held after the running, with food, music, and entry by free donation. The published details are forecast from the previous edition, so the exact schedule and race list may still change.
