1. What is a Half Marathon?

A half marathon is a road running event of 21.0975 kilometers (13.1094 miles). It's half the distance of a full marathon and is a popular challenge for runners of various skill levels.

2. How Does the Calculator Work?

The calculator uses the basic time-distance-pace relationship:

\[ Time = \frac{Distance}{Pace} \]

Where:

\( Time \) — Estimated finish time (hours)
\( Distance \) — 21.0975 km (half marathon distance)
\( Pace \) — Your running speed in km/h

Explanation: The calculator converts your pace (km/h) into an estimated finish time for a half marathon.

3. Importance of Pace Calculation

Details: Knowing your estimated finish time helps with race planning, pacing strategy, and setting realistic goals for training and competition.

4. Using the Calculator

Tips: Enter your average running pace in km/h. The value must be positive (typically between 8-20 km/h for most runners).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a theoretical time based on constant pace. Actual race times may vary due to terrain, weather, and pacing variations.

Q2: What's a good half marathon pace?
A: This varies widely by fitness level. Beginner runners might average 9-11 km/h, while elite runners may exceed 20 km/h.

Q3: How can I improve my half marathon time?
A: Consistent training, long runs, speed work, and proper nutrition are key factors in improving performance.

Q4: Should I maintain the same pace throughout?
A: Most runners benefit from negative splits (slightly faster second half), but this requires practice and discipline.

Q5: How does elevation affect my time?
A: Significant elevation changes can substantially impact your finish time, which this calculator doesn't account for.
