Jirkov (Czech pronunciation: [ˈjɪrkof]; German: Görkau) is a small town situated between Most and Chomutov in the Ústí nad Labem Region of the Czech Republic and is situated on the Chomutov - Ústi nad Labem railway line. Although geographically close to the German border, the presence of hills along the border hinders land travel to Germany.
Jirkov is also a place of cultural and sports activities. A citizen can attend many sports clubs and organizations, use a large number of cycle routes around the town or participate in one of the town-organized activities. One such sport activity is Jirkov Crossmarathon.(Wikipedia)
