The National Hot Rod Association Spring Nationals is an annual drag racing event held at National Trail Raceway, located between Hebron and Kirkersville, Ohio.
In 1963, Carl Rader, Sr., constructed National Trail Raceway, a one-quarter mile long drag racing track, between Hebron and Kirkersville, Ohio. Since 1972, National Trail Raceway has held at least one National Hot Rod Association (NHRA) drag racing event each year. The most popular event at the track is the NHRA Spring Nationals that take place each June. More than 120,000 spectators routinely come to this event. Only two other tracks have hosted NHRA events longer than National Trail Raceway. The fastest average speed run at the track was in a Top Fuel dragster that averaged 326.32 miles per hour.
