During a trip to the Blackwater 100 GNCC event in the early 1990s, the Shaver Family came in contact with race promoter, Dave Coombs. After some discussion with Big Dave, they felt their family farm may be suitable for a GNCC event. Dave would send his Son-in-Law, Jeff Russell, to Crawfordsville, Indiana to see the farm firsthand. After a brief tour, the decision was made to add the event to the GNCC schedule beginning in 1995. The event was named the "Ironman" in honor of two-time GNCC champion, Bob Sloan, who hailed from Indiana and passed away in 1994.
Over the years the Ironman GNCC would grow with large numbers of spectators and racers converging on the facility. In 2012, the decision was made to break ground on a new motocross facility that would begin hosting Lucas Oil Pro Motocross Championship events beginning in 2014. Since then, the events have grown in size including the 2021 Ironman GNCC which saw a record 2,710 racers take part in the event.
