(CNN) -- Wild horses, raging winds and energy-sapping heat in the land of Genghis Khan; welcome to the Mongolian steppe.

This vast expanse of savannah and grassland is the setting for the world's longest horse race -- the Mongol Derby.

Equestrian's toughest test is perhaps the last place you'd expect to find a teenager from the English county of Hampshire.

But Lara Prior-Palmer isn't like other teenagers.
