The Mongol Derby is a self-guided 1000km adventure race cross the incomparable Mongolian steppe, one of the world's last remaining wildernesses and cradle of the largest land empire ever created under Chinggis Khaan. At the heart of the Mongol Derby is the horse station system, called Urtuus in Mongolian. Based on the Great Khaan's postal system which could relay messages at speed from the furthest corners of the empire, the Mongol Derby rebuilds this network to stage one of the most ambitious equine events in history. Participants are mounted on a series of native Mongolian horses, which are sacred in the enduring Mongolian nomadic culture. They eat and rest with nomadic families along the way, so experiencing Mongolia as it would have appeared in the time of the Great Empire. Integral to the event is an extensive back-up system providing medical, veterinary and communications support to the horses and riders, but all being well, riders are alone in the wilderness with their semi-wild steeds. This is a multi-faceted adventure, not just a horse race. Riders change horses every 40kms, ensuring that the horse power is always fresh and full of running, while they themselves are pushed to their physical limits. Riders need to look after themselves in extreme conditions, navigate independently, and overcome difficulties using their initiative. All of these elements combine to make the Mongol Derby the ultimate equine adventure, which entices the world's finest adventurers, riders and audience. About Cool Earth: The simple idea behind Cool Earth is that rainforests are worth much more to the human race left standing, helping to cool the planet, than they are cut down for timber or burnt to clear land for cattle ranching. Cool Earth works with local rainforest communities to protect rainforest from being cut down. With our supporters, we make a difference by; Only protecting rainforest that is in imminent danger and without our intervention would be cleared. Protecting rainforest that forms a protective blockade for tens of thousands of acres of adjacent forest. Working with local communities to make sure that they are best placed to protect the rainforest. Making sure the money our individual sponsors give us goes directly to the rainforest. We spend less than 10% of our supporters' money on administration. Protecting areas with high levels of biodiversity which store at least 260 tonnes of CO2 per acre.
