The 200 metres begins on the curve of a standard track (where the runners are staggered in their starting position, to ensure that they all run the same distance), and ends on the home straight. The ability to "run a good bend" is key at the distance, as a well conditioned runner will typically be able to run 200 m in an average speed higher than their 100 m speed. Usain Bolt, however, ran 200 m in the world-record time of 19.19 sec, an average speed of 10.422 m/s, whereas he ran 100 m in the world-record time of 9.58 sec, an average speed of 10.438 m/s.
