Rollercoaster 3.0 is a cross-country trail race in Zielona Góra, Poland, offering 13 km, 23 km, and 53 km distances. It takes place around the end of September. The name reflects the course: a hilly forest race with sharp changes in effort rather than steady pacing.
The course features demanding natural paths with steep climbs and technical descents, requiring runners to possess both climbing strength and control. Trail enthusiasts are the primary audience, particularly those seeking a challenging run in mountainous, wooded terrain over a standard road race.
