What to Expect on Bohemian Border Bash Race

Bohemian Border Bash Race is a self-supported mixed-terrain ultracycling event that circumnavigates the historic borders of Bohemia through Czechia, Germany, Poland, and Austria. Designed as a fixed-route adventure, the race combines remote gravel roads, forest tracks, forgotten tarmac, and relentless mountain climbs into one of Central Europe’s toughest endurance challenges.

Riders pass through the Elbe Sandstone Mountains, Ore Mountains, Bohemian Forest, Eagle Mountains, Table Mountains, and the Giant Mountains, following a fixed GPX route that traces the ancient borders of Bohemia.

Bohemian Border Bash Race follows a strict self-supported philosophy. Riders are responsible for their own navigation, food, accommodation, and mechanical repairs, with no outside assistance permitted.
