Coke Zero just launched their Rooftop Racer Cup competition, where racing fans will be able to log into the game on Coke Zero’s website site each race weekend to compete against one another for great prizes, including a trip to the Ford 400 NASCAR Sprint Cup race at Homestead!

Here’s how the competition works… All potential players have to sign up on the Coke Zero website and then play the Rooftop Racer online game during race weekends through October. The competitors who post the best scores each week will receive cool prizes — such as hats, t-shirts, signed mini-hoods, and race kits.

At the end of the 12 week period, the person with the highest score (race 12 score plus your top 3 from earlier weeks) will win the grand prize: a VIP trip for two to the Ford 400 race at Homestead in Miami!

While people can play as many times as they want, once they post their score, that’s it for the week (so they should make sure it’s a good one): http://www.RooftopRacer.com

Real Coke taste and Zero calories isn’t the only thing on the line. The Race for the Cup is now underway.
