Track Information

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 eight divisions at the track. The Super Late Model and Late Model divisions race on the half-mile track. The Super Stocks, Sport 4's (stock four cylinders modified for racing), 1/4 mile Late Models, V6 Roval, 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.
