100 m (one hundred metres) is the shortest outdoor sprint race distance in athletics. The 100m Olympic champion is often named "the fastest man/woman in the world". The 200 m record had often been at a faster average speed than the 100 m record.
Sprinters typically reach top speed after somewhere between 50–60 m.Their speed then slows progressively towards the finish line. Maintaining that top speed for as long as possible is a primary focus of training for the 100 m.
