The Oregon Bicycle Racing Association (OBRA) is the official sanctioning body of bicycle racing in Oregon, Southwest Washington and parts of Northern California. We work with race promoters to put on world class events within the region. We sanction road, track, mountain bike, enduro, cyclecross and gran fondo events. OBRA provides the community and framework for successful events. We provide insurance, race equipment, competitions, calendars, training, judging, timing services, marketing, membership services and many other services to make bicycle racing safe, enjoyable and accessible. OBRA sanctions over 390 events and clinics throughout the year.
