Day 6: 11 Jan

On Jan 11 was the second day of the marathon stage, and contestants raced for a total of 450 km on their way back to Arequipa from their marathon bivouac in Tacna. Racing vehicles started out two at a time from the starting line of the SS (Special Stage), which was set up by the sea at the end of a 42 km liaison route. After racing the 314 km first half, they traveled on a 66 km neutral zone, and finally raced the 136 km second half. Once across the finish line, racers took a 153 km liaison back to Arequipa, making this a long day with 711 km of driving in total.

As the inter-mountain areas became draped in fog late in the afternoon, the poor visibility forced organizers to discontinue the day's competition at 5:05 pm; 425 km into the race at CP (check point) 3. Everyone was informed at whichever CP they arrived at that the race has been discontinued and instructed to make a diversion to paved road and head on to the bivouac in Arequipa.

The Teruhito Sugawara and Katsumi Hamura crew on their HINO500 Series truck delivered a solid race again this day, climbing from their 15th place starting position to 12th overall in the trucks category by the time they reached CP3. This concluded the five stages of the first week.
