Marathon mountain bike race

The UCI has established a championship series for such events, the Marathon World Cup. The 2014 UCI rules limit events to distances between 60 km (37 mi) and 160 km (99 mi). Almost all of the participants are elite professional mountain bike racers. There is an annual world championship event, the UCI Mountain Bike Marathon World Championships. The races can be run over as a single or multi-lap course, however, the course cannot cover the same lap more than three times.

Non-UCI events routinely cover much longer distances. The typical event in the USA is either based on time, typically 12 or 24 hours, or distance, the most common being 100 miles (160 km). Events based on hours typically allow either people to compete individually or as part of the team. Distance events are almost all solo events. The number of these events and those taking part in them have grown greatly. The first such events began to be held routinely in the early 1990s typically had less than 50 racers. In 2006 nearly 100 events were held and most had more than 150 racers.

The world's largest mountain bike marathon race by the number of participants is the Birkebeinerrittet, 95 kilometres (59 mi), held annually in Norway. While the distance is short for a marathon mountain bike event, the number of participants and history make it noteworthy.
