The event is held in Prague's Letňany area and follows the Urban Challenge OCR format, meaning the distance is only one factor: participants also navigate obstacles. September in Prague is often cloudy with average rainfall of about 45 mm, potentially making the race a practical test of grip, pacing, and comfort in cool weather rather than a straightforward road race.
