Traxxas Off-Road Trucks

The Indianapolis Motor Speedway expanded its entertainment offerings on May 23 -- Coors Light Carb Day – as the Formula Off-Road Presented by TRAXXAS series competes on the world's most famous racetrack.

The Stadium Super Trucks will race on a modified course on the frontstretch of the oval and a portion of the infield road course, which will incorporate man-made ramps at multiple locations.

"My first trip to Indy as a competitor was in 1993 driving for A.J. Foyt," said series founder Robby Gordon, who is a 10-time Indianapolis 500 competitor. "I grew up watching Rick Mears, A.J. and others race at the Speedway and dreamed of driving there, but I never imagined we would race off-road trucks at Indy. I have a lot of great memories from Indianapolis and this will be another one added to the list."

11 a.m.: Verizon IndyCar Series Practice
12:30 p.m.: Indy Lights Presented by Cooper Tires Freedom 100

Mark Cuban to be Indy 500 honorary starter

Indiana University graduate Mark Cuban, an entrepreneur and owner of the Dallas Mavericks, will be the honorary starter of the Indianapolis 500 on May 25.

"Whether it's winning an NBA Championship or the honor of waving the green flag to start the Indianapolis 500, there are certain sporting events that are monumental for any true sports fan," Cuban said.  "I am excited to come back to Indiana, not just to attend, but actually participate in this historic race."

10-time Indy 500 starter Sir Jack Brabham dies

Sir Jack Brabham, a four-time Indianapolis 500 starter and patriarch of a racing dynasty that includes 10-time Indianapolis 500 starter Geoff Brabham and Indy Lights driver Matthew Brabham, died May 19. He was 88.

"Every time an Indy car runs at the Indianapolis Motor Speedway, you can find roots that trace back to Jack Brabham's rear-engined Cooper Climax T54 that he drove to ninth place in the 1961 Indianapolis 500," Indianapolis Motor Speedway President J. Douglas Boles said. "In addition to starting the rear-engine revolution at IMS, Brabham competed in four Indianapolis 500 Mile Races and designed race cars that competed in the ‘500.’ ’’
