1. What is Half Marathon Pace?

The Half Marathon Pace is the average time it takes to complete one kilometer (or mile) during a half marathon race (21.0975 km). Knowing your pace helps with race strategy and training.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Pace} = \frac{\text{Time (hours)}}{21.0975} \]

Where:

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

3. Importance of Pace Calculation

Details: Knowing your pace helps you set realistic goals, maintain consistent effort during the race, and plan training sessions effectively.

4. Using the Calculator

Tips: Enter your total race time in hours, minutes, and seconds. The calculator will compute your average pace per kilometer.

5. Frequently Asked Questions (FAQ)

Q1: What's a good half marathon pace?
A: This varies greatly by fitness level. Beginners might aim for 6:30-7:30 min/km, while elite runners can maintain under 3:00 min/km.

Q2: How does this differ from full marathon pace?
A: Full marathon pace is typically 10-15% slower than half marathon pace due to the increased distance and fatigue.

Q3: Should I maintain the same pace throughout?
A: Most runners benefit from even pacing, though some prefer negative splits (faster second half) if well-trained.

Q4: How accurate is this for race prediction?
A: It's accurate for calculating pace from a known time, but predicting race time from training pace depends on many factors.

Q5: Can I use this for mile pace?
A: This calculates km pace. For mile pace, either convert the result (1 mile = 1.609 km) or use 13.1094 as the distance (half marathon in miles).
