1. What is Half Marathon Pace?

The Half Marathon Pace Calculator determines your average pace per kilometer for a half marathon (21.0975 km) based on your target finish time. This helps runners plan and maintain consistent speed during the race.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Time \) — Total race time in minutes
• \( 21.0975 \) — Half marathon distance in kilometers

Explanation: The equation divides your total time by the race distance to find your average pace per kilometer.

3. Importance of Pace Calculation

Details: Knowing your target pace helps with race strategy, prevents starting too fast, and ensures even energy distribution throughout the race.

4. Using the Calculator

Tips: Enter your target finish time in minutes (e.g., 120 for 2 hours). The calculator will show your required pace per kilometer.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this pace calculator?
A: It provides mathematically precise average pace, but actual race pace may vary due to terrain, weather, and race conditions.

Q2: Should I maintain this exact pace throughout?
A: Most runners benefit from slightly negative splits (faster second half). Consider terrain when planning pace variations.

Q3: What's a good half marathon pace?
A: This varies by fitness level. Beginners might aim for 6:30-7:30 min/km, while competitive runners may target sub-4:00 min/km.

Q4: How does this compare to marathon pace?
A: Half marathon pace is typically 15-30 seconds per km faster than marathon pace for the same runner.

Q5: Can I use this for training runs?
A: Yes, it helps determine target paces for long runs and tempo workouts based on your race goals.
