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 maintain consistent speed throughout the race.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

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

Explanation: The formula 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 output your required pace in minutes:seconds per kilometer.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this pace calculator?
A: It provides a mathematical average. Actual race pace may vary based on course elevation, weather, and running strategy.

Q2: Should I run exactly this pace the whole race?
A: This is your average pace. Many runners use negative splits (slower start, faster finish) or adjust for hills.

Q3: What's a good half marathon pace?
A: This varies greatly by fitness level. Beginner runners might aim for 6:00-7:00 min/km, while elites run under 3:00 min/km.

Q4: How does this compare to marathon pace?
A: Half marathon pace is typically 10-20 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 preparing for a half marathon.
