World Racing Group (OTCBB: WRGI) and Alltel Wireless (NYSE: AT) are excited to announce their second major event partnership of 2008. Alltel, the official wireless provider of fans and America�s largest network providing coverage across the nation, will be the title sponsor of the Alltel Ohio Speedweek featuring the World of Outlaws Late Model Series. This four-race event follows the highly successful Alltel DIRTcar Nationals partnership that opened the 2008 racing season. �We were very pleased by the fan support during the Alltel DIRTcar Nationals in February, so expanding our partnership with the World Racing Group was a very easy decision,� said Samira Zebian, director of sponsorship marketing for Alltel Wireless. �Becoming title sponsor of the Alltel Ohio Speedweek is another great way to reach hard core racing fans and introduce them to Alltel�s products and services. Like we did in February at the Alltel DIRTcar Nationals, we will have the Alltel Fan Zone, the Alltel Wireless NASCAR Stock Car and hospitality at all four events during the Alltel Ohio Speedweek.� Alltel also intends to crown an Alltel All-Star for the event, which features races July 24 at Muskingum County Speedway in Zanesville, Ohio; July 25 at Tony Stewart�s Eldora Speedway in Rossburg, Ohio; July 26 at Dave Blaney�s Sharon Speedway in Hartford, Ohio; and July 27 at Eriez Speedway just across the border in Erie, Pa. The top five finishers each night will qualify to become the Alltel Ohio Speedweek All-Star, making a possible 20 different drivers eligible for the title. Voting will begin online at www.AlltelAllStar.com after the final Alltel Ohio Speedweek event July 27 from Eriez Speedway, and fans each night will receive hero cards and posters. �We are excited Alltel Wireless experienced so much success in February that it wants to expand its involvement with the World Racing Group as the title sponsor of the Alltel Ohio Speedweek,� said World Racing Group Chief Marketing Officer Ben Geisler. �From the Fan Zone to the show car to the Alltel All-Star contest, Alltel is once again taking a very proactive role in the activation of its partnership with us, which will no doubt benefit fans and racers alike.� For more information on the Alltel Ohio Speedweek and the World of Outlaws Late Model Series, visit www.WorldofOutlaws.com.
