Sprint Speed Test — How Fast Can You Run?

Quick Answer: To test your sprint speed, tap Start below, sprint in a straight line outdoors for 30–60 meters, and read your top speed in the stats. For a more precise result, time a measured 40 m or 100 m and use the calculator: speed = distance ÷ time. Fit adults typically sprint 20–30 km/h (12–19 mph); elite sprinters exceed 40 km/h.

How to Run a GPS Sprint Speed Test

  1. 1. Find open space

    A track, field or quiet straight path with open sky. Buildings and trees make GPS readings jumpy.

  2. 2. Lock GPS first

    Tap Start and wait until the GPS status shows a good signal before you run — this takes 10–30 seconds.

  3. 3. Hold the phone firmly

    Use an armband or hold it in your hand. A loose pocket adds noise.

  4. 4. Sprint 30–60 m, then read Max

    Run all-out for 5–8 seconds. Your Max speed is kept after you stop. Press Reset between attempts.

Phone GPS updates about once per second, so it can miss a very short peak. For a precise number, use the timed method below.

Timed Sprint Calculator

Measure a distance, have a friend time you with a stopwatch from a flying or standing start, and enter the results.

This gives your average speed over the distance. Your top speed is higher, because the first seconds are spent accelerating. A “flying” sprint — timing only the last 20–30 m after a run-up — gets closer to top speed.

How Fast Is a Good Sprint?

Direct Answer: Recreational adults usually reach a top sprint speed of about 20–30 km/h (12–19 mph). Trained team-sport athletes often reach 30–35 km/h. Usain Bolt peaked at about 44.7 km/h (27.8 mph) during his 9.58-second 100 m world record in 2009, averaging about 37.6 km/h over the full distance.

Frequently Asked Questions

Can my phone measure my sprint speed?

Yes, roughly. GPS measures speed once per second, which works for sprints of 5 seconds or more. For short bursts, a timed distance is more precise.

How fast can a human run?

The fastest recorded human speed is about 44.7 km/h (27.8 mph), reached by Usain Bolt in 2009.

How do I convert my 100 m time to km/h?

Divide 360 by your time in seconds. For example, 360 ÷ 15 s = 24 km/h.

What about measuring running pace?

For steady runs, use the running speed tracker, which shows speed and pace per km or mile.
