But there’s a bit of a twist in the Rallye des Gazelles: no GPS allowed. No Google Maps. No technology of any kind. The navigators use paper maps and a compass to find their way around the dunes of Morocco over the eight days of competition. The teams must decide the best way reach the checkpoints along the route, with penalties awarded for driving extra kilometers. The days start at 6 a.m., and each leg typically takes 10-13 hours to complete, though the entirely off-road route is changed each year.
