After an unprecedented wildfire scorched the state of Colorado and forced the Pikes Peak International Hill Climb competition to cancel earlier this summer, the 90th running of this unique show of brawn and agility starts this weekend at the 14,110 ft mountain's base. Taking part will be a racing variety of the new Audi RS5, though it won't be alone. In a display of its commitment to performance and the company's recent acquisition of DUCATI, the famed Italian motorcycle brand, Audi will commit both Audi RS5 Coupe and DUCATI Multistrada 1200S to this year's race. What's more, both brands invite their fans to experience the Audi RS5 Coupe and DUCATI Multistrada 1200S in person. Starting tomorrow, August 10th, to September 10th, you can tweet the reason why you would like to drive/ride both vehicles together. The winner of the contest will get an all-paid trip for two to Sonoma, California, with attendance at the Audi Sportscar Experience One-Day Program at Infineon Raceway and the DUCATI Riding Experience Program. Entry is open to those who are 25 years old or older, with valid driver and motorcycle licenses. For more details, visit the Audi & DUCATI #ComeTogether site.
