Racers from fifteen countries have descended on Mongolia's capital city, Ulaan Baator, for the start of the Mongolia Bike Challenge presented by Orbea. The third edition of the MBC will start tomorrow morning in the heart of downtown, and continue for ten stages across the mountains, rivers and steppes of Mongolia. Organizers report the field this year is the strongest yet; a number of top professional riders have decided to test themselves in what has been described as a tough but rewarding race. Joining the professionals on the starting line will be adventurous amateurs from around the world. Follow along over the next ten days for daily photos by Margus Riga, and recap videos by Aaron Larocque and Nic Genovese of Pinkbike - the Official Media Partner of the Mongolia Bike Challenge.
