Hallett Motor Racing Circuit (HMRC) is a 1.8 mile, 10 turn road racing course located in the rolling Osage Hills of North Eastern Oklahoma. It is located 35 miles west of Tulsa, Oklahoma, at the Highway 99 exit of the Cimarron Turnpike.
HMRC has over 80 feet of elevation change and is considered “technically difficult.” It has wide, grassy run-off areas with tire barriers supported by concrete, and zero Armco barriers. HMRC is unique in that it can be run in either clockwise or counter-clockwise directions making it two completely different race courses. For over 30 years, HMRC has played host to auto racing, motorcycles, and high speed karts.
