Unlike long-track speed skaters, short trackers don't go up against the clock. They go against each other. Starts, especially in the 500-meter race and the relays, are critical because getting to the inside position on the oval is so important. Athletes are allowed one false start. After that, they're disqualified.
Spills are routine.
The event starts with a series of preliminary heats, culminating in a four-person final. The men's relay is 5,000 meters, while the women's is 3,000. Some of the best action, though, takes place with the relays. Team members can skate as many laps as they want in relays, and someone who finishes a lap can come back in, if the teams wants it. The changeover, like the baton exchange in track and field, is critical.
