The Speed-Distance-Time Formula
The fundamental relationship between speed, distance, and time is: Speed = Distance ÷ Time. From this, you can derive: Distance = Speed × Time and Time = Distance ÷ Speed. Enter any two values and this calculator solves for the third.
Speed is typically expressed in km/h or mph for running and cycling, or m/s in scientific contexts. Distance is usually in kilometers or miles, and time in hours (or hours:minutes for practical use).
| Pace (min/km) | Speed (km/h) | Speed (mph) | Effort Level |
|---|---|---|---|
| 3:00 /km | 20.0 km/h | 12.4 mph | Elite sprint pace |
| 3:30 /km | 17.1 km/h | 10.6 mph | Sub-elite race pace |
| 4:00 /km | 15.0 km/h | 9.3 mph | Competitive 10K |
| 4:30 /km | 13.3 km/h | 8.3 mph | Good recreational pace |
| 5:00 /km | 12.0 km/h | 7.5 mph | Average runner |
| 6:00 /km | 10.0 km/h | 6.2 mph | Easy/recovery pace |
| 7:00 /km | 8.6 km/h | 5.3 mph | Beginners / walk-run |
Speed vs Pace: Converting Between the Two
Runners often use pace (time per km or mile) while cyclists and scientists use speed (km/h or mph). To convert between them: Speed (km/h) = 60 ÷ Pace (min/km). For example, a 5:00/km pace equals 60 ÷ 5 = 12 km/h.
Understanding speed in km/h helps when comparing running to other activities, analyzing GPS data from sports watches, or using treadmill speed settings. Most treadmills in Europe show km/h; in the US, mph. A common treadmill speed for jogging is 8–10 km/h (5–6.2 mph), while race-pace running starts around 12–15 km/h (7.5–9.3 mph).

Frequently Asked Questions
How do I convert pace to speed?
Speed (km/h) = 60 ÷ Pace (min/km). For example, 5:00/km pace = 60 ÷ 5 = 12 km/h. For mph: multiply km/h by 0.621371.
What speed is a 4-hour marathon?
A 4-hour marathon over 42.195 km requires an average speed of 42.195 ÷ 4 = 10.55 km/h (6.55 mph), or a pace of 5:41 per kilometer.
What treadmill speed equals a 30-minute 5K?
A 30-minute 5K requires a pace of 6:00/km = 10.0 km/h. Set your treadmill to 10 km/h (or 6.2 mph in US units) to train at this pace.
How do I calculate average speed from GPS data?
Divide total distance (km) by total time (hours). For example, 10 km in 55 minutes (0.917 hours) = 10 ÷ 0.917 = 10.9 km/h average speed. GPS watches do this automatically, but this formula lets you verify the calculation.
What is the world record marathon speed in km/h?
Eliud Kipchoge holds the world record marathon of 2:00:35, covering 42.195 km at an average speed of 21.0 km/h (13.0 mph), or a pace of 2:51 per kilometer — a sustained speed that very few humans can match even for a single minute.
