The race was run on the SCCA Runoffs layout, not the INDYCAR Grand Prix layout as was done the previous year, as it was made necessary as a result of kerbing damage in the Turn 5-6 chicane during the Verizon 200 NASCAR-INDYCAR meeting. The Runoffs course utilised the old Formula One course with the newer Snake Pit section.
