Rhino Charge (annual)

Rattling through the African bush, a map juddering on your knee, brush crashing around your ears amid the danger of territorial animals... you're on the Rhino Charge, an annual 4WD rally race held in the Kenyan bush.

Each team brings its own 4WD vehicle, and competitors are given the locations of "guard posts" in the bush. They head off into the wilds around and the team that covers the least distance to get to all the posts is the winner.

This extreme test of driving skills and physical endurance is recognized as the toughest off-road challenge in the world.
