WIR originally opened as KK Sports Arena, a nod to its location on County Trunk KK. The main track is a half-mile D-shaped paved oval. Inside the half mile track is a smaller quarter-mile oval. Originally a dirt track, the quarter mile was paved in 1968. The half mile track was added around the existing quarter mile the following year. There are six divisions at the track. The Super Late Model and Late Model divisions race on the half-mile track. The Super Stocks, Sport 4's, and Wisconsin Sport Trucks divisions race on the quarter-mile track. The Figure 8 cars end programs on the Figure 8 track inside of the quarter-mile. An automated timing and scoring system was set up for the 2007 season, and each race car carries a transponder. The Fox River Racing Club began helping promote the weekly events in 1975.
Special events
The track had an annual American Speed Association event when the sanctioning body was in existence. The track resumed hosting ASA events after the series was reorganized, and it held an event in 2007 for the ASA Midwest Tour. That event, the Dixieland 250, is now part of the ARCA Midwest Tour schedule and is one of the most prestigious events on the calendar, attracting NASCAR championsKevin Harvick and Ron Hornaday Jr. in 2009 and Kyle Busch in 2017. The race was part of the NASCAR Midwest Series between 1998 and 2004 and had 13 races under NASCAR banner. Earlier the USAC Stock Car series had raced at the track. The track has hosted an annual Red, White, and Blue State Championship Series for super late models since 1972. The series consist of three races in June, July, and August. The series changed from Saturday nights to Thursday nights to combine with the weekly series in 2009. The series was part of the Midwest Challenge Series and later part of the Wisconsin Challenge Series. 7,832 people watched Dick Trickle win the first red race. ASA National Tour ran a race at the facility in 2002. The race was won by Kevin Cywinski.

The track has hosted an annual "Eve of Destruction" each September since 1993 and it is the track's annual season finale for the oval track. The Eve of Destruction is one of the biggest events hosted at track, as the 10,000 seat raceway is generally packed. Drivers compete in a variety of unusual events such as chain races, spin to win, trailer races, etc. In between races, fans are entertained by stunt car drivers. Ten school buses compete in a survival-of-the-fittest competition, where the last bus standing wins. Track owner Roger Van Daalwyk described the Eve of Destruction: "We kind of wreck everything." During the 2017 Eve of Destruction, a local driver died from injuries sustained in a figure-eight race.
