Hallett Motor Racing Circuit, Racing Circuit

Hallett Motor Racing Circuit is a road course set in the rolling Osage Hills of north-eastern Oklahoma, roughly 35 miles west of Tulsa. The 1.8-mile (2.897 km) layout features ten turns and more than 80 feet of elevation change, giving it a reputation as a technically demanding circuit. A distinctive feature is that it can be run in either direction, creating two effectively different courses for drivers to learn. The circuit opened in 1976 and has hosted national-level competition over the decades, including rounds of the IMSA GT Championship, the Trans-Am Series, and Can-Am racing. Today it remains an active venue for SCCA road racing, motorcycle lapping, karting, and drifting, alongside private and corporate events. The site also runs driver education and a race school, plus high-speed touring track days. The racing surface was repaved in January 2025, refreshing the track for the regional motorsport community.
