[Mongolia Bike Challenge The Mongolia Bike Challenge is an epic, 6-stage mountain bike race in the land of Genghis Khan. It is open to both professional and high-level amateurs. Racing more than 100 off-road kilometres a day with 14,000 metres of total climbing makes the MBC one the most challenging races in the world. However, private yurt and tent accommodation, Western-style catering, world-class logistics and organization, and the company of some very like-minded and adventurous people, make it one of the best experiences possible on two wheels.]
