Cyclocross is a form of competitive cycling that takes place on a mixed terrain, including grass, dirt, and obstacles. Races typically involve multiple laps around a short course, where riders must navigate various challenges such as steep hills, barriers, and mud. Cyclocross bikes are designed for this type of racing, featuring lightweight frames and knobby tires for better traction. Races are usually held in the fall and winter months, making them unique in the cycling calendar. Participants often dismount and carry their bikes over obstacles, showcasing both riding skills and physical endurance. Cyclocross is popular in Europe and has been growing in popularity in other regions, including the United States.
