Běh klatovskou Hůrkou is a 4.8 km autumn race in Klatovy, in the Plzeň Region of the Czech Republic, held on the second Saturday in October. Locals also call it Pětka, even though the adult route is just under five kilometres. Atletika Klatovy organizes the event, which is part of the Ešus liga, a district series for off-track running around Klatovy.
The adult race starts and finishes on the track at the athletics stadium, then sends runners for three laps around the Klatovská Hůrka forest park. The stadium finish provides a proper final straight, making close sprints part of its appeal. The event began with children's races, with adults added a year later. Youth categories remain important as the race is part of the Plzeň Region Youth Running Cup. Fields include club athletes from across the region and local runners; recent editions have drawn over 200 competitors, with large children's and youth fields plus separate men's and women's adult races. The course records are 17:41 for men and 20:29 for women.
