INDIANAPOLIS, Ind. - It was a huge Carb Day at the Indianapolis Motor Speedway, packed with events and thousands of race fans.
It could have even been the biggest Carb Day ever at IMS. It was a day thousands of fans and drivers enjoyed, especially a three-time winner who was just as pumped as the fans.
Indy 500 Champion Helio Castroneves sang along with the crowd during the pit stop competition.

Carb Day also featured the final day of Indy 500 practice and the Indy Lights Freedom 100 Race, which had a very close finish.
Rock band Journey headlined the Carb Day concert in turn four.
Castroneves told CBS4 just 98 days ago that this 100th Indy 500 would be special for him and the fans are fueling his excitement in his pursuit of win number four.
“These fans are incredible. It just pumps you up and makes you go and make it happen," he said.
Castroneves said he feeds off the excitement from the fans.
"Absolutely. That’s why, for me the fans are so important because they make me feel energized, you know?”
Friday's Carb Day also had beautiful weather with temperatures in the 80s.
