Run on the Mother of all Roads.  The Williams Route 66 Marathon showcases the best of what Tulsa has to offer! Start your race in downtown Tulsa, home of the largest concentration of Art Deco architecture outside of Miami, and then make your way through Tulsa’s vibrant and diverse neighborhoods and the campus of Tulsa University. If there’s one thing you can count on at the Williams Route 66 Marathon, it’s tons of on-course support from the local community and plenty of fun. Our neighborhoods host block parties all along the course to welcome and cheer on the runners! The Williams Route 66 Marathon is a USATF certified course and a Boston Qualifier (see Boston Athletics Association for qualifying times)
