Herzlauf Oberösterreich is a charity running event held in October in Upper Austria, organized by Stadtmarketing Traun. It accommodates a broad range of participants: beginners, regular runners, professional runners, Nordic walkers, children, and school classes, offering a separate race for schoolchildren and class registration.
The event supports children with heart conditions, with tax-deductible donations. It is part of the Herzlauf series throughout Austria, which includes events in Vienna, Salzburg, Vorarlberg, Styria, Carinthia, Tyrol, and Lower Austria. Ambassadors and partner organizations also lend their support.
