Staying in Burkina Faso, one task involves loading a bicycle with many items and delivering the items to a particular stall in a maze of market stalls. Then teams choose between trying to impress local celebrities with their tribal dancing skills or panning for gold. A "U-Turn" in which a team must perform both tasks, puts one team so far behind that they are in jeopardy of being eliminated, and bring down the scorn of racers on the team that penalized them.
