1. What is Pace Calculation?

Pace calculation determines how fast you're moving per unit of distance. For runners, it's typically measured in minutes per kilometer or kilometers per hour. This calculator focuses on km/h for half marathon distance (21.0975 km).

2. How Does the Calculator Work?

The calculator uses the basic pace formula:

Where:

• Distance — Typically 21.0975 km for a half marathon
• Time — Total time taken to complete the distance

Explanation: The formula converts your total time into hours, then divides the distance by this time to get your average speed in kilometers per hour.

3. Importance of Pace Calculation

Details: Knowing your pace helps with race strategy, training planning, and performance tracking. For half marathons, maintaining a consistent pace is key to optimal performance.

4. Using the Calculator

Tips: Enter your total time in hours, minutes, and seconds, and the distance (default is 21.0975 km for half marathon). All values must be valid (distance > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's a good half marathon pace?
A: This varies by fitness level. Beginners might aim for 8-10 km/h, while elite runners can exceed 16 km/h.

Q2: How does this differ from min/km pace?
A: km/h is the inverse of min/km (60/min/km = km/h). This calculator gives speed rather than time per unit distance.

Q3: Should I use actual race distance or GPS distance?
A: For official races, use the certified distance (21.0975 km). For training runs, GPS distance may vary slightly.

Q4: How accurate is this for partial distances?
A: The calculation works for any distance, but pace may vary in actual runs due to terrain, fatigue, etc.

Q5: Can I use this for full marathon training?
A: Yes, though marathon pace is typically slower than half marathon pace. Adjust distance to 42.195 km for full marathon.
