The Mongol Derby is the longest and toughest horse race in the world. The 1000km course recreates Chinggis Khaan's legendary empire-busting postal system, with riders changing horse every 40km, and living with herders or camping under the stars.
Each year around 40 professional, semi-professional and enthusiastic amateur riders compete against each other for the derby crown. To stand a chance of finishing riders must balance survival skills and horsemanship and to stand a chance of winning an extra level of determination and no small amount of luck is required.
Enduring the elements, semi-wild horses as well as unfamiliar food and terrain, completing the derby is an achievement few can boast.
