Pannonian Challenge began in the mid-1990s and has run under its current name since 1999, growing into the largest extreme sports and urban culture festival in southeastern Europe, built around competitions in skateboarding, BMX, inline skating and scooter riding rather than the music-first format of most Croatian summer festivals.
