The first mountain bike competitions were held in California (USA) in the early eighties. Since then the discipline has grown very fast, in all aspects. The first World Championships to be officially recognized by the UCI dates back to 1990. A World Cup was set up the following year.
CROSS-COUNTRY (part of the Olympic programme)
Cross-country races are held over undulating circuits (with technical descents, forest roads, rocky paths and obstacles) of 5 to 9 km. The race varies from 1 h 45 minutes to 2 h 30 minutes depending on the category.
The marathon event is a long version of cross-country held over a course of 60 to 120 km. A special feature is that riders from all categories, from enthusiasts to professionals, race together. The marathon event is held in a mountainous region. In contrast to the Olympic cross-country format, the riders never pass the same point twice.
