Cyclocross is a form of competitive cycling that takes place on a mixed terrain, often featuring grass, dirt, and obstacles. Races typically last 30 to 60 minutes and involve riders navigating a course that includes barriers, steep hills, and tight turns. Cyclists often dismount and carry their bikes over obstacles, making it a physically demanding sport. The bikes used in cyclocross are similar to road bikes but have wider tires for better traction and stability. Races are usually held in the fall and winter months, attracting both amateur and professional cyclists who enjoy the challenge of varied conditions and technical skills.
