Road course ringer, also known as Road course specialist,Road course expert, or Road runner, is a term used to describe a non-NASCAR driver who is hired by a NASCAR team to race, specifically, on road courses. Current NASCAR national-level road courses include Infineon Raceway, Watkins Glen International, Road America and Circuit Gilles Villeneuve; historic circuits include Riverside International Raceway, Heartland Park Topeka, Brainerd International Raceway, etc. NASCAR describes the term, "drivers who specialize in turning both left and right," and says that "perhaps the greatest road-course ringer in NASCAR history might be Dan Gurney" after he won four straight NASCAR races at Riverside International Raceway. He lapped the field at the 1964 event.
