 This race started in Buenos Aires on 27 September, and ran up through the Andes and Bolivia to Lima, Peru, and then back to Buenos Aires, taking 15 days, ending on 12 October with stages held each day.This horrendously gruelling race was held in the most varied and difficult conditions imaginable- held at variable times in hot and dry deserts, insect-ridden jungles with crushing humidity and cliff drops, and mountain passes in freezing cold, snowy weather at extremely high altitude, sometimes in darkness.Early in the race Fangio hit a large rock and damaged the car's driveshaft, which in the next town would have to be replaced.
