After revving up for nearly a month with practice runs and qualifying laps, 33 Indy racecar drivers will motor up Gasoline Alley to the 2.5-mile oval speedway, where they’ll compete for the checkered flag in the 87th Indianapolis 500 on May 25. ABC’s live coverage of pre-race activities begins at 11 a.m. ET, and the waving of the green flag is at noon.
