The Mattoni Liberec Trail Run begins and ends at Dr. E. Benes Square in Liberec. From there, runners head out of the city and onto unpaved terrain. This October trail race, held in the Czech Republic, offers both a 12 km and a 22 km distance. It serves as the final event in the RunCzech series, organized by RunCzech s.r.o., and features a mixed format rather than a pure road race.
The course transitions from asphalt to forest paths within the Jizera Mountains. Participants will run through wooded areas, pass a water reservoir, and traverse a granite quarry before returning to Liberec. The route provides a mountain-like experience rather than a typical city run. The event caters to runners seeking a shorter trail challenge as well as those opting for the 22 km distance. Its presence across multiple editions confirms its established position on the Czech running calendar.
