Thursday Night Motocross at PIR

Thursday Night Motocross at Portland International Raceway in Portland, Oregon is one of the most remarkable institutions in American motocross, the longest continuously running nighttime motocross series in the country, going strong since 1966. That puts the series among the oldest continuously operating motorsports programs of any kind in the United States, and the nearly-60-year run on the same hallowed PIR infield is a story unlike any other in American motocross.

The format is weekly Thursday night racing from April through September every single summer. That kind of operating consistency across nearly six decades is unusual in any motorsports format and is genuinely rare in motocross specifically, where weekly series come and go and most regional racing programs have run for a fraction of the time. Thursday Night MX has outlasted nearly every other weekly racing series in the country.

Around 200 racers show up every Thursday, ranging from peewees through full pros. That broad skill range is part of what defines the series. Most regional racing programs cluster around a specific competitive level. Thursday Night MX serves the full spectrum, which means the racing produces the kind of multi-generational family scene that has built the series' reputation across decades of operation.

Pricing is genuinely unmatched at $10 for adults and $5 for kids 6 to 12. The pricing structure reflects the operating philosophy more than the cost basis. The series is built around accessibility, and the rates have stayed reachable for nearly six decades to serve the broader Pacific Northwest motocross community.

The schedule is consistent. Practice at 5pm, racing at 6pm, every Thursday from April through September.

The track itself uses the Portland International Raceway infield, a specially-built motocross layout with soft dirt and notably steep hills that take advantage of natural elevation, lit for night racing. The steep-hill terrain is the property's distinguishing feature and is what gives the layout its character. The night lighting is the operational element that makes the Thursday-night format possible, and the combination of steep hills and night lights has produced the kind of weekly Pacific Northwest race scene that exists nowhere else.

Concessions on the property handle visiting families, and the kind of authentic local race-night atmosphere that has built across decades cannot be manufactured. The series is the entry point for generations of Oregon and Washington racers, the place where careers start and where families gather all summer.

The location is on Portland International Raceway grounds in north Portland, easy access from Interstate 5 and Interstate 405, minutes from downtown. PIR also hosts the National Hot Rod Association and SCCA-sanctioned road racing among its other operations, putting Thursday Night MX inside a broader motorsports facility that supports the kind of operating infrastructure the series depends on.

For Pacific Northwest motocross riders, racing under the PIR lights on a summer Thursday night with Mount Hood visible in the distance is one of the genuinely special experiences in American motorsports. The pricing is unmatched. The tradition is unmatched. The lighting is unmatched.
