This week, a Brazilian made history by running the 100 meters in under 10 seconds. Erik Cardoso clocked an impressive 9.93 seconds — setting a new Brazilian and South American record. But what does this actually mean? And what truly separates a sprinter from a well-trained recreational runner?

What Does Running 100 Meters in 9.93 Seconds Mean?

Running 100 meters in 9.93 seconds means hitting top speeds above 40 km/h (about 25 mph) and maintaining an average speed over 36 km/h (around 22 mph) throughout the race. We're talking pure speed — power, explosive strength, and finely tuned acceleration and stride technique.

To put how exceptional this is into perspective: a good amateur runner typically completes 100 meters in about 12 to 13 seconds, while popular recreational runners take around 14 to 16 seconds. In practice, when Erik finishes the 100 meters, you might still be around the 60-meter mark.

What Makes Sprinting So Special?

Sprinting requires a completely different physiology than long-distance running. It’s about fast-twitch muscle fibers, neuromuscular recruitment, and maximum force applied in milliseconds.

The technique is also a different story: the start is explosive, posture shifts quickly, strides begin short and rhythmic, evolving into long, powerful steps — all in under 10 seconds. It’s a very short duration, but insanely intense and demanding precise technique.

What About the Marathon?

On the other hand, marathon running demands another kind of training: energy efficiency, pace management, and a highly developed aerobic system. You can’t really compare Usain Bolt with Eliud Kipchoge — they are different sports, even though both are literally just running.

More Than Just a Number

“9.93 seconds” is more than just a number. It’s the result of years of dedication to achieving perfect explosiveness.

Next time you go for a run, why not time yourself over 100 meters? Remember: running fast is also a skill — and like any skill, it requires specific training.
