WRL is an amateur series promoting and operating endurance races at road courses across the United States. Founded on the premise that racing should be simple, affordable, safe and fun, WRL employs a "skinny" rulebook outlining classes based on a power-to-weight formula designed to keep racing close regardless of car and budget. WRL is a professionally operated non-contact series where cars from all major road racing sanctions are eligible, including SCCA, NASA, the budget endurance series, and others. WRL accepts other sanctioning body licenses and also provides a structured licensing program.
