Background
Portland International Raceway (PIR) is a motorsport facility in Portland in the U.S. state of Oregon. It is part of the Delta Park complex on the former site of Vanport, just south of the Columbia River. It lies west of the Delta Park/Vanport light rail station and less than a mile west of Interstate 5.

The track hosts the IndyCar Series, Formula E, ICSCC and SCCA and OMRRA road racing, the ARCA Menards Series West, the NASCAR Xfinity Series, and SCCA autocross events. Additionally, the PIR grounds are host to OBRA (Oregon Bicycle Racing Association) bicycling races on the track and the surrounding grounds. The facility includes a dragstrip and a motocross track.

Practice
The first and only practice was held on Saturday, June 1, at 8:30 AM PST, and would last for 20 minutes. Sam Mayer, driving for JR Motorsports, would set the fastest time in the session, with a lap of 1:14.493, and a speed of 95.204 mph.

Qualifying
Qualifying was held on Saturday, June 1, at 9:00 AM PST. Since Portland International Raceway is a road course, the qualifying system is a two group system, with two rounds. Drivers will be separated into two groups, Group A and Group B. Each driver will have multiple laps to set a time. The fastest 5 drivers from each group will advance to the final round. The fastest driver to set a time in that round will win the pole.

Under a 2021 rule change, the timing line in road course qualifying is "not" the start-finish line. Instead, the timing line for qualifying will be set at the exit of Turn 11. Sam Mayer, driving for JR Motorsports, would win the pole after advancing from the preliminary round and setting the fastest time in Round 2, with a lap of 1:13.375, and a speed of 96.654 mph.

Frankie Muniz was the only driver who failed to qualify.
