The league was started in 2016 by Donald Strout. Since then, the league has continued to attract simracing enthusiasts who wish to race in a friendly, yet competitive setting. As iRacing has evolved, with new tracks and new cars being launched, while others are moved to the legacy list, the league has evolved with it. The original road racing car was the Pro Mazda, a medium powered single seater. This was replaced by the IndyPro 2000 series PM-18 car in season 15, and in turn replaced by the F3 car for season 29, and again by the Super Formula Lights for season 32. The NASCAR selection of cars and an oval series was introduced in season 8. From season 22 the Next Gen cars replaced the older class cars for the ovals series, and starting season 33, NASCAR Trucks are being used for the oval series.
To offer a choice for those not so interested in open wheelers or ovals, there are two separate touring car road track series, one using the GT4 cars where the occasional rain shower occurs and a GT3 series with more consistent conditions. There is also a series using the ARCA Stock Cars.
The league is run by the members on an enthusiast and non profit basis.
From the beginning, the league had participation from both Europe and North America, and there have been champions from seven different countries in the road series. In the ovals, by season 33, only US based drivers have made it to the top.
