1. What is the Pace Equation?

The pace equation calculates your running pace by dividing your target time by the race distance. This helps runners maintain a consistent speed throughout their race.

2. How Does the Calculator Work?

The calculator uses the pace equation:

Where:

• \( P \) — Pace (minutes per mile or kilometer)
• \( T \) — Target time (minutes)
• \( D \) — Distance (miles or kilometers)

Explanation: The equation calculates how many minutes you should spend covering each unit of distance to achieve your target finish time.

3. Importance of Pace Calculation

Details: Knowing your target pace helps you run efficiently, avoid starting too fast, and achieve your desired finish time in a half marathon.

4. Using the Calculator

Tips: Enter your target finish time in minutes, select the distance (miles or kilometers), and choose your preferred pace unit. All values must be valid (time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's a good half marathon pace?
A: This varies by runner. Beginners might aim for 10-12 min/mile (6-7.5 min/km), while advanced runners may target 6-8 min/mile (3.7-5 min/km).

Q2: How do I convert between min/mile and min/km?
A: 1 mile = 1.60934 km. To convert min/mile to min/km, divide by 1.60934. Multiply by 1.60934 for the reverse.

Q3: Should I account for hills in my pace?
A: Yes, adjust your target pace for hilly courses. Add 2-3 seconds per mile for each 10 feet of elevation gain.

Q4: How does temperature affect pace?
A: Expect to slow by 1-3% for every 10°F above 55°F (12.8°C). Adjust your target time accordingly.

Q5: What's negative splitting?
A: Running the second half faster than the first. Many experts recommend pacing 2-3% slower than target for the first half.
