ALL THE WILD HORSES follows international riders from around the world as they compete in the Mongol Derby in Mongolia, the longest and toughest horse race on the planet. In this race across 700 miles of Mongolian steppe the riders are on their own, navigating from horse station to horse station where they change horses every 30 miles. They have to deal with dehydration, hypothermia, exhaustion, extreme weather, swollen rivers, attacking dogs and roaming wolves. The riders stay the nights out in the wild or with nomad families. To choose a wrong horse at a horse station could get them bucked off, losing their mount in the process, or suffer more serious injuries. Filmmaker Ivo Marloh rides the 1000-kilometre race twice to embed himself in the individual stories and document exactly what compels riders from all around the world to risk broken bones, life-threatening injuries, or their life savings for an experience that will change their lives forever, in one of the last true wildernesses on Earth, on the back of wild horses
