This cross-border running event takes place in a town that has been divided into two parts since 1920: Cieszyn in Poland and Český Těšín in the Czech Republic.

In Poland the event is known as the Cieszyński FORTUNA Bieg.

Czechs call it Těšinský FORTUNA Běh.

The event features two races, a 10k and a 2k for young athletes. Each race usually attracts well over 1,000 entries.

Starting at the stadion miejski in Cieszyn in Poland, participants in the 10k race run two laps through both parts of the town, crossing the border four times.

The route runs along both banks of the Olza river (which forms the border) and across two bridges.
