Full-points doubleheader races on the Belle Isle, Houston and Toronto street courses return for a second year. The event on the 1.634-mile, 10-turn temporary circuit at Reliant Park in Houston moves from early October to late June, which bundles the doubleheaders into a two-month span.
The annual night race at Texas Motor Speedway on June 7 separates the Detroit and Houston dates. The second IndyCar Series race at the 2.5-mile Pocono Raceway on July 6, followed by a night race at the .875-mile Iowa Speedway on July 12, bisect Houston and the doubleheader on the Exhibition Place circuit in Toronto. The span represents racing on four consecutive weekends.
Additionally, the Milwaukee race has been moved from mid-June to Aug. 17, while the fifth-annual race at Barber Motorsports Park in Birmingham, Ala., has taken a date two weeks later to April 26.
Four road and street course races will start the season, while the drive to the championship in August includes road course races at Mid-Ohio Sports Car Course and Sonoma Raceway, the race on the 1-mile Milwaukee oval and the closing race on the 2-mile Auto Club Speedway oval.
“With the most diverse calendar in all of motorsports, we want the build-up to the championship to reflect our versatility by featuring a short oval, a road course and superspeedway in the final three consecutive weekends of our schedule to highlight the talent of our drivers,” said Miles.
