More about what is Cyclocross.

Cross, as you should now know, is a Winter sport. The Belgians dominate on the international scene. It is done on a bike that closely resembles a road bike, but with different brakes, knobbier tires, and a little bit beefier frame and fork. The courses are usually around two miles to a lap and consist of varying combinations of road, dirt, grass, mud, and sand. We race in all conditions shy of deadly. I've raced in sunshine, rain, and snow. Along the course there is usually, but not always one or more short hills that are considered unrideable, either because they are too steep, the approach is odd, or there are wooden hurdles about 18 inches tall at the top and bottom of the hill. There are also often other spots on the course where two or three of the aforementioned hurdles are in sequence and you have to dismount and carry your bike over them. You do this as fast as possible, running over the barriers at 15 to 18 miles an hour, bike in hand, then leap back onto your bike again. It's rad. The link below is a great montage of cyclocross. And the music is pretty good too, Here it Goes by OK Go.
