INDYCAR will return to “The Fastest Short Track on the Planet,” July 11-13, 2025, for the INDYCAR Race Weekend. Be part of this weekend full of fun, excitement, entertainment and great racing during the only NTT INDYCAR SERIES doubleheader weekend of the year. Iowa Speedway in Newton, Iowa is a .875-mile tri-oval with variable banking that drives like a superspeedway. With laps under 18 seconds and races lasting almost two hours, Iowa Speedway is exceptionally demanding physically and mentally on drivers. It was designed with the second generation of SAFER Barrier around the entire perimeter of the racetrack.
