1. What is the Half Marathon Target Time Calculator?

The Half Marathon Target Time Calculator estimates your finish time based on your planned pace and the race distance. It helps runners plan their race strategy and set realistic goals.

2. How Does the Calculator Work?

The calculator uses the basic running formula:

Where:

• \( T \) — Target time (hours:minutes:seconds)
• \( D \) — Distance (miles or kilometers)
• \( P \) — Pace (minutes per mile/km)

Explanation: The calculation multiplies your pace (time per unit distance) by the total distance to predict your finish time.

3. Importance of Pace Calculation

Details: Knowing your target time helps with race planning, pacing strategy, and setting intermediate time goals during the race.

4. Using the Calculator

Tips: Enter the race distance (standard half marathon is 13.1 miles or 21.0975 km) and your planned pace in minutes and seconds per mile/km.

5. Frequently Asked Questions (FAQ)

Q1: What's a good half marathon pace for beginners?
A: Beginner runners typically aim for 10-12 minute/mile (6:15-7:30 min/km) pace, finishing in 2:10-2:40.

Q2: How does elevation affect target time?
A: Hilly courses will slow your pace. Add 10-20 seconds per mile for each 100 feet of elevation gain.

Q3: Should I use mile or kilometer pace?
A: Use whichever unit you're more comfortable with. The calculator works with both.

Q4: How accurate is this prediction?
A: This assumes even pacing. Actual time may vary due to terrain, weather, and race conditions.

Q5: What if I want negative splits?
A: For negative splits (faster second half), calculate using your average target pace.
