Hamster racing is a sport in which hamsters are placed in hamster wheels or hamster balls – often fitted to miniature racing vehicles – and raced down a straight 9 meter (30 ft) course. The hamster crossing the finish line in the shortest amount of time wins. According to a 2001 media report, the world-record time for this course setup is 38 seconds. Events may feature as few as two hamsters or many teams of hamsters and human pit crews. Hamster balls may be simple spheres or feature many design modifications purported to increase the performance and style of the race vehicle.
