Frequently asked questions

What's a fast 100m for an amateur?

Sub-12 seconds is quick for a club sprinter; sub-11 is competitive. Usain Bolt's world record averages over 10 m/s for the whole race.

Why do sprinters reach top speed before the finish line?

In a 100m race, elite sprinters typically hit their maximum velocity around 50-60 metres in and then gradually decelerate for the rest of the race, since the human body cannot sustain peak acceleration output for the full distance.
