Roaring with 6.5 horsepower Honda motors, American Indoor Karting's adult GT-5 karts top out at up to 40 miles per hour and achieve 1.5 lateral Gs as they careen around a professional course during eight-minute races. Track marshals solicit racers for waiver signatures before conducting a short safety briefing to explain track protocol, indicating heat assignments and distributing DOT-approved helmets and neckwear. Specially prepared to enhance grip and reduce skidding, the quarter-mile concrete tracks test the custom-built fleet's smooth hydraulic brakes and stellar shock stability on hairpin turns and blow-dried straights. Younger drivers race separately in 5.5-horsepower junior karts; behind the scenes, a full-time mechanic inspects and tests each kart to ensure safety and minimize handling differences. Individual computerized reports trumpet each competitor's fastest lap and lap average, as well as issuing heat rankings and overall winners for the day.

Drivers can release energy from their wound-up bodies with a laser-tag arena and an inflatable play area. Check the calendar to schedule a sprint through time on the course or experience the thrill of using a mouse to click into the future.
