The Blue-Emu Maximum Pain Relief 500 is a NASCAR Cup Series race held annually at the Martinsville Speedway in the spring. It has been run since 1950 and is held in conjunction with an Gander RV & Outdoors Truck Series race the preceding day. The race has been notably sponsored by Goody's Powder, which sponsored the event from 1996 to 2002, and again from 2007 to 2012. The race is the second oldest race in NASCAR, only to the fall race at the same track.
