Cyclocross (CX) is a form of bicycle racing that consists of many laps of a short course over mixed terrain, with course features that may involve dismounting your bike, carrying it to navigate obstacles and remounting your bike. It mixes multiple athletic endeavors, namely riding and running, with a strong emphasis on skillful bike handling. Races usually take place in a park, on a short circuit with each lap being between 1 to 3 kilometers long over grass, mud, trails, gravel, concrete and with a few obstacles for competitors to negotiate – sand pits, logs, barriers, etc. Races typically last 25 minutes to an hour, with the number of laps varying based on course length, conditions and speed. Competitors start as a group and spread out – the faster riders will complete more laps and the officials keep track placement throughout the race. The cyclocross season in Wisconsin runs from September through December.
