The Coca-Cola Co. is offering free bottles of Coke Zero to US consumers.

The company, which last week offered consumers a free bottle each if one of its Coca-Cola Racing Family won last weekend's Coke Zero 400 NASCAR race, extended the offer despite the failure of any of the 13 drivers to win the event.

Any US resident 13 years of age or older can visit between now and 13 July and follow the instructions to receive a coupon for a free 20-ounce bottle of Coke Zero. For each claim, US$1 will be donated to charity foundation the Victory Junction Gang Camp on behalf of the first 10,000 people who visit for a coupon.

Founded by Kyle Petty - a founding member of the Coca-Cola Racing Family - and his wife Pattie in honour of their late son Adam, the Victory Junction Gang Camp helps children with chronic medical conditions or serious illnesses by providing "life-changing" camping experiences.

"We were really rooting for one of our drivers to get to Victory Lane and deliver a taste of victory to people across the US," said Bill Kelly, senior vice president, Coca-Cola Brands, Coca-Cola North America. "In the end, it was a great race and that's reason enough to follow through with our offer to give away free Coke Zero and to continue our support of Kyle Petty's Victory Junction Gang Camp."

The debut of the Coke Zero 400 Powered By Coca-Cola is part of a ten-year sponsorship agreement between Coca-Cola North America (CCNA) and International Speedway Corporation (ISC).
