Běh Debří

Běh Debří is a late-autumn race held in the Debř forest park, taking place on the Czech state holiday commemorating the founding of independent Czechoslovakia. It is the series' shortest and oldest competitive run, organized annually since 2004, and it maintains a fixed date on the calendar. Registration for all categories opens in the morning, with the first races beginning shortly thereafter. The event accommodates all age groups. The youngest children compete in a 100 m race, while adults complete two full loops, covering a total of 5.4 km. This adult course, though short, features over 110 m of elevation gain within the forest park. Běh Debří is unique within the series for offering categories for children of all ages, including those not yet attending kindergarten.
