Motor-paced racing and motor-paced cycling refer to cycling behind a pacer in a car or more usually on a motorcycle. The cyclist (or stayer in this case) follows as close as they can to benefit from the slipstream of their pacer. The first paced races were behind other cyclists, sometimes as many as five riders on the same tandem. Bordeaux-Paris and record attempts have been ridden behind cars. More usually races or training are behind motorcycles.
