Král Točné - Žaludská osma is a public running event in Prague with two race options: an 8.5 km run and a shorter 3 km run. The listing labels the longer race as Desítka and the shorter one as Pětka, even though the posted distances are not exactly 10 km and 5 km.
The available listing does not give a detailed route, but the name points to Točná, a Prague district on the city’s southern edge. The event is connected with the Dusmen Grand Prix Facebook page and appears in a Czech public race calendar aimed at runners looking for local events around Prague.
