Pochod Krajem SeveroČeských Jednotek is a long-distance hiking and trail event based in Ústí nad Labem, with its route linking Ústí nad Labem and Terezín before returning to Ústí nad Labem. The main distance is 100 km, placing the headline event in ultratrail territory, but the program also offers shorter options: a 58 km afternoon route, 43 km and 29 km morning routes, plus marathon and half-marathon options.
The course uses the terrain around the Ústí nad Labem district, with the Ore Mountains and the Bohemian Central Highlands providing a rougher, more varied feel than a flat road race. It is organized by Spolek přátel Aktivních Záloh and KČT LOKO Teplice, and it belongs to the wider set of races around Ústí nad Labem. The event is in its tenth edition, suggesting a local fixture built for experienced walkers, ultratrail runners, and people who want a demanding point-to-point day out rather than a standard city race.
