A truly wild race, the Big Five Marathon is held on the Entabeni Game Reserve of the South African savannah. Traveling through the habitats of elephant, rhino, gazelles, buffalo, giraffe, lion and leopard, with nothing separating runners from the animals, this isn't for the faint of heart. Taking runners through valleys, down ridges, and up steep climbs, this is a favorite among thrill-seeking trail running buffs. With a landscape that includes sheer ravines, raging waterfalls and redstone dunes, it is perhaps the most unique way to experience this type of landscape.
