IMI Motorsports Complex, located in Calhan, Colorado, is a versatile motorsports facility catering to a wide range of disciplines. Established in the early 2000s, IMI has grown from a small dirt oval into a multifaceted complex featuring a paved road course, a dedicated karting track, and a sprawling off-road area.

The road course is a 1.7-mile, 11-turn circuit known for its challenging and flowing layout. Characterized by significant elevation changes and a mix of high-speed sweepers and tight, technical corners, it demands precision and car control. The asphalt is generally well-maintained, providing good grip levels. The layout promotes overtaking opportunities, particularly under braking into several of the sharper corners. Runoff areas are adequate in most sections, enhancing safety.

Technical characteristics include a blend of decreasing radius turns, off-camber sections, and a long straight that allows for considerable speed. The elevation changes are a significant factor, affecting braking points and car balance. The track is challenging for both drivers and engineers, requiring a well-balanced setup to maximize performance.

IMI hosts a variety of racing events, including road racing, time attack, drifting, and karting. Local and regional racing series frequently utilize the facility, and it's also popular for open track days and driver education programs. The karting track is a separate, shorter circuit designed specifically for kart racing. The off-road area is used for various off-road events, including rock crawling and off-road racing.

What makes IMI unique is its combination of diverse racing disciplines within a single facility, coupled with the challenging road course layout that is both rewarding and demanding for drivers of all skill levels. The stunning backdrop of the Colorado plains adds to the overall appeal of the complex.
