INDIANAPOLIS – Indianapolis Motor Speedway President J. Douglas Boles confirmed to NBC Sports that discussions were had about shifting the Brickyard 400 to the road course before the decision was made to keep the NASCAR Cup Series on the 2.5-mile oval

The track’s NASCAR weekend shifts from late July to Sept. 9 next year. The track will host the final Cup race before the playoffs begin.

Boles said Wednesday that the road course was considered an option but rejected for multiple reasons.

“As fans know and as we know and as NASCAR knows, the Brickyard 400 over the last several years has struggled,” Boles told NBC Sports. “We believe to continue to make it viable and frankly to grow it, we had to look at everything.

“We actually had a conversation about the road course in February in Daytona. Mark (Miles, CEO of Hulman & Co., INDYCAR and IMS parent company) and I met with the folks in NASCAR in New York City. We talked it through.

“Ultimately, the Indianapolis Motor Speedway is about the oval and NASCAR is about the oval. What makes this race special for the drivers is they get to drive on a track that Ray Harroun ran on, Wilbur Shaw won on, and you can recall the names that meant something to this sport.

“We felt committed to making the oval work.”

It was the heat, Boles said, that was the primary factor for the move to the fall. Boles noted the customer feedback from annual surveys and said that more than the racing product on track, heat was an overriding complaint.

“We survey our fans after every year,” Boles said. “The one thing we hear more than anything, the biggest complaint about the Brickyard 400 is the heat in the middle of the summer and you can’t shade this place. You can’t add more shade. The heat is the number one factor. We would make a move to move it out of the heat.

“Now we’ve moved it to an event where they will crown their regular season champion and they will set their 16 drivers for the playoffs. For us, that is another talking point.

“This addresses the number one concern that our customer has. The second or third, depending on the year, is that the race is just a race and doesn’t have real meaning to the rest of the season, so now we’ve also addressed that concern as well.”

One concern that arises from a September date is the potential of going head-to-head with the Indianapolis Colts. The NFL traditionally releases its schedule in April, so NASCAR will know whether the Colts are in town on Sunday, Sept. 9 well in advance.

Boles and IMS are already working toward an amenable solution.

“We completely understand it’s NFL season, and we’re in a city where the Colts are,” he said. “So we have begun those conversations, even ahead of announcing this with the folks at the Colts, so we can do the best we can to limit the weekends we go head to head with the Colts in this market.”
