1. What is Running Speed?

Running speed is the rate at which a runner covers distance, typically measured in kilometers per hour (km/h). It's inversely related to running pace (minutes per kilometer).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( S \) — Speed in kilometers per hour (km/h)
• \( P \) — Pace in minutes per kilometer (min/km)

Explanation: Since there are 60 minutes in an hour, dividing 60 by the pace (minutes per km) converts it to km per hour.

3. Importance of Pace-Speed Conversion

Details: Understanding both pace and speed helps runners compare performance across different distances and track progress in training.

4. Using the Calculator

Tips: Enter your running pace in minutes per kilometer (e.g., 5:30 min/km should be entered as 5.5). The calculator will output your equivalent speed in km/h.

5. Frequently Asked Questions (FAQ)

Q1: What's a good running speed?
A: This varies by fitness level. Recreational runners typically maintain 8-12 km/h, while elite runners can exceed 20 km/h.

Q2: How does speed relate to marathon time?
A: A consistent 10 km/h speed would complete a marathon in about 4 hours 13 minutes (42.2 km / 10 km/h = 4.22 hours).

Q3: Why use pace instead of speed?
A: Runners often prefer pace (min/km) as it directly relates to race timing and is easier to track during runs.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact - any variation comes from inconsistent pacing during actual running.

Q5: Can I convert speed back to pace?
A: Yes, use the inverse formula: P = 60 / S (where P is pace in min/km and S is speed in km/h).
