Public ticket sales have started for all multiday tickets for the BITNILE.COM Grand Prix of Portland on Aug. 8-10 at Portland International Raceway (PIR).

Both the NTT INDYCAR SERIES and INDY NXT by Firestone will conduct vital races in their respective championship runs on the 12-turn, 1.964-mile natural terrain road course.

Multiday Grandstand seats, General Admission tickets and parking passes are available for purchase. Single-day tickets will be released later in the summer for both events.

Grandstand seats are available at multiple price points, with 3-Day Grandstand seats at the BITNILE.COM Grand Prix of Portland starting at $85. Weekend General Admission tickets are available for $75.

Children 12 and under receive free General Admission when attending either event with a ticketed adult. Additionally, Rookie Racers memberships are on sale offering unique, behind-the-scenes experiences for kids ages 5-12.

Fans can also purchase Pit and Paddock passes, plus Champions Club and Champions Club+ options to further enhance the race weekend experience.

For a limited time while supplies last, the Champions Club membership includes an NTT INDYCAR SERIES Paddock Pass and offers premium access and exclusive benefits such as a personalized event credential, pre-race grid walk and more. Champions Club+ includes all the above benefits plus a Pit Pass, which provides access to pit lane during practice and qualifying sessions. A Paddock Pass offers entry to “the locker room of motorsports” to get up close to the drivers, cars and teams throughout the weekend.

All ticket pricing and options, including parking passes and RV Club spaces, are posted online at RacePortland.com. Both events feature no fees on order processing for online orders.
