The Mongol Rally is an adventure rally that begins in the UK and ends in Ulaanbaatar, the capital city of Mongolia. It's primary purpose is to raise money for charities in Mongolia in a way that is fun, unique, and adventurous. Every team participating in the Rally has agreed to raise money for the official event charity (Christina Noble Children's Foundation) and on top of this we are also raising money for Cancer Research UK and Help for Heros.

The Rally has been called the "greatest adventure in the world" and is organized by the League of Adventurists International Limited, a private company registered in the UK. The principal launch is from Goodwood racecourse with other starting points in Czech Republic and Italy. The Rally is designed as an adventure rather than a traditional rally race, there is no set route and no support from the organizers along the way. No awards are given for the first place finisher; the overall goal is to just complete the 8-10,000 mile journey from the start to Ulaanbaatar. Most teams complete the journey in four to six weeks.

Vehicles used in the rally must have an engine displacement of less than 1,200cc and must be newer than 2002 (as per the Mongolian Government, for import reasons). Vehicles with larger displacements can be used in exchange for increased charity fundraising and exceptions to the rule are considered for vehicles of "notable unusualness or high comedic value". Ambulances, fire engines, and other vehicles that are of high use to Mongolian charities are also welcomed. Upon reaching Mongolia, vehicles are either donated to charity or auctioned off and the proceeds are donated to the charities.

No support or accommodations are made for teams participating in the rally. Traveling in vehicles ill-equipped for 10,000 miles across mountains, desert, and frozen tundra will lead to a much richer experience along the way as we'll need to rely on locals for help, directions, repairs and hospitality. The inaugural rally took place in 2004. 6 teams started and 4 completed the journey. The 2006 Rally began on July 22 with 167 cars. 117 teams successfully completed the trip. In 2009, 359 teams started the Mongol Rally, and approximately 281 made it to Ulaanbaatar. In 2010, team numbers of the rally reached 500 cars and 2000 people.
