The Carrera Panamericana was a border-to-border sedan (stock and touring and sports car) rally racing event on open roads in Mexico similar to the Mille Miglia and Targa Florio in Italy. Running for five consecutive years from 1950 to 1954, it was widely held by contemporaries to be the most dangerous race of any type in the world. It has since been resurrected along some of the original course as a classic speed rally. Original 1950 After the 2,178 mile (3,507 kilometer) north-south Mexican section of the Pan-American Highway was completed in 1950, a nine-stage, five-day race across the country was organized by the national government to celebrate its achievement and attract international business. The 1950 race ran almost entirely along the new roadway. The first of five annual races began on May 5, 1950 and was entered by racers from all over the world representing virtually every motor sport: Formula One, sports cars, rallying, stock cars, endurance racing, hill climbing, and drag racing. Because it started at the border with Texas, it was especially attractive to all types of American race drivers from Indy cars to NASCAR. Bill France, the founder of NASCAR, was there for the first race as well as later races. The Mexican government's representatives worked closely with the American Automobile Association and other motor sports groups in the United States to organize and promote the event which was limited to stock sedans with five seats. Piero Taruffi and Felice Bonetto, both Italian F1 drivers, entered a pair of Alfa Romeo coupes specially constructed for the event. However, many of the 132 competitors were ordinary unsponsored citizens from the United States, Mexico, and elsewhere. The entrants included nine women drivers. The first race ran from north to south beginning in Ciudad Juárez, Chihuahua, across the international border from El Paso, Texas, and finishing in Ciudad Cuauhtémoc, Chiapas (formerly known as El Ocotal) on the Guatemala-Mexico border opposite from La Mesilla, Guatemala. The event comprised nine "legs" or stage. At least one leg was run each day for five consecutive days. The elevation changes were significant: from to above sea level, requiring among other modifications the rejetting of carburetors to cope with thinner air. Most of the race was run between and . The first four places were won by American cars and American drivers. The winner, Hershel McGriff, drove an Oldsmobile 88 at an average speed
