Bob Long, 70, became the oldest person to ever complete the Mongol Derby and the oldest to ever win it.
The Mongol Derby is an annual event which sees riders race 1,000 kilometers across the Mongolian steppe. The route is inspired by the Mongol Empire's pioneering postal service which was used to send messages.
Riders are monitored from afar by a team of experts and are able to stay with local families along the way.
The horses they ride are from local herds and are not entirely domesticated. A team of vets ensure the animals are not pushed too much and are rested every 40 kilometers.
Long took just seven-and-a-half days to complete the challenge but said the physical strain took its toll on his body.
A team of four riders finished the mammoth task in joint third.
Horses have always played a huge role in Long's life and he was inspired to take on the epic challenge after watching a film about the event.
