Best chance to get ahead of the trucks:
Do well in the first special stage of 60km. I would think that you don't want to start just in front of the trucks.
"The seaside resort of Mar del Plata brings to mind lazing around, especially after the competitors have mingled with the crowd during the public presentation ceremony on 31st December. For the short warm-up special stage, they will nevertheless be allowed to pass by the seafront, where the small dunes to be crossed will represent the first hurdle. In this simple exercise, the fastest time will establish a first winner and determine each competitorís position in the rankings. After this challenge, there will be a long liaison section to be covered to Santa Rosa de la Pampa."
After this special, throw in a pair of street tires and hit the 796km liaison. Talk about a sore butt!
