Indy 500 track is 2.5 miles long. The track has four distinct turns and straightaways, a layout unchanged since the facility opened in 1909. The front and back straightaways are 5/8th of a mile each, with the “short chute” straightaways between Turns 1 and 2 and Turn 3 and 4 at 1/8th of a mile each. Each of the four turns is 1/4th of a mile long.
