Questions tagged [cyclocross]

Cyclocross is a form of bicycle racing consisting of short laps over many differing terrains, typically including grass, sand, mud, pavement, rocks and anything the course designer finds at the race site. Each lap also usually includes steep run-ups, barrier obstacles forcing the rider to get off the bike. Cyclocross is not to be confused with gravel riding or gravel bicycles.
