Běhej lesy Klínovec is the summer mountain stage of the series, held on 11 July 2026 near Boží Dar, the Czech Republic's highest town. Běhej lesy ('Run the Forests') is a series of eight trail races in the Czech Republic's most beautiful natural spots, with distances from 3 to 50 km, Dr. Max kids' races and an overall 'Lord and Lady of the Forest' ranking; the state forestry company Lesy ČR is its founding partner. The courses climb the slopes of Klínovec, the highest point of the Ore Mountains, through mountain meadows, conifer forests and peat bogs with views over Saxony. It is cooler up here, and it is one of the most 'mountain' stages of the series. The Ore Mountains offer a UNESCO-listed mining landscape, the peat-bog trail at Boží Dar, silver-rich Jáchymov and the spa town of Karlovy Vary nearby.
