Thursday is the first day of Iowa Speed Week as the 360 Nationals get underway this evening. It marks the beginning of the busiest time of year for tourism in Knoxville – thousands of people will make their way to Knoxville and Marion County over the next two weekends for the races. Knoxville Raceway Marketing Director Brian Stickel expects many of the biggest names in sprint car racing to be in the lineups over the next four days as drivers get ready for the 52nd Goodyear Knoxville Nationals. Of course, you can live coverage of both Nationals events on KNIA/KRLS and kniakrls.com, beginning tonight with the first night of qualifying for the 360 Nationals. Live Trackside will air at 6pm Thursday – live race coverage begins at 7:15.
