Owned and managed by Portland Parks & Recreation, the 291-acre Portland International Raceway (PIR) includes a nearly two-mile paved loop racetrack. PIR receives no City funding but generates revenue for operation and maintenance on-site through a broad spectrum of motorized and non-motorized races and events. The Portland International Raceway Master Plan describes allowed uses and planned environmental restoration at the site. Short track cross-country mountain biking and cyclocross races occur on temporary courses set up in the motorcross course and through grassy areas adjacent to the paved racetrack. Off-road cycling is limited to programmed events.
