Cross-country (XCcycling is the most common discipline of mountain biking. Cross-country cycling became an Olympic sport in 1996 and is the only form of mountain biking practiced at the Olympics.

 

Cross-country cycling is defined by the terrain on which it is performed. XC courses and trails consist of a mix of rough forest paths and singletrack (also referred to as doubletrack depending on width), smooth fireroads, and even paved paths connecting other trails. Most cross-country trails are deemed “easy” or “intermediate”, however, some paths can be difficult, even for experienced riders, such as the trails used during the Summer Olympic Games.
