I want to know the answer to the following question:
When did the Suntrust Indy Challenge stop being run at RIR?
All the background I'm provided with is that "Southside Speedway has acted as the breeding grounds for many past NASCAR legends including Richard Petty, Bobby Allison and Darrell Waltrip, and claims to be the home track of NASCAR superstar Denny Hamlin.". Is that enough to answer the question?
