1. What is the Interval Time Calculation?

The interval time calculation helps runners determine how long specific distance segments should take based on their target pace. This is essential for interval training and race pacing strategies.

2. How Does the Calculator Work?

The calculator uses the basic formula:

Where:

• \( T \) — Time (minutes or seconds)
• \( D \) — Distance (miles or meters)
• \( P \) — Pace (min/mile or sec/m)

Explanation: The calculation multiplies distance by pace to determine the expected time to cover that distance at the given pace.

3. Importance of Interval Timing

Details: Accurate interval timing helps runners maintain consistent pacing during workouts, improves race strategy, and allows for precise training adaptations.

4. Using the Calculator

Tips:

• For mile-based calculations: enter distance in miles and pace in minutes per mile
• For meter-based calculations: enter distance in meters and pace in seconds per meter
• All values must be positive numbers

5. Frequently Asked Questions (FAQ)

Q1: Can I use kilometers instead of miles?
A: The calculator currently supports miles and meters. For kilometers, convert to meters (1 km = 1000 m) and use seconds per meter pace.

Q2: How do I convert min/mile to min/km?
A: Multiply min/mile by 0.621371 to get min/km (since 1 mile ≈ 1.60934 km).

Q3: What's a good interval pace for beginners?
A: Interval pace is typically faster than easy pace but sustainable for the distance. A common recommendation is 5K race pace + 5-10 seconds per mile.

Q4: How does this help with marathon training?
A: Knowing your interval times helps structure speed workouts that improve running economy and lactate threshold.

Q5: Can I calculate lap times for a track?
A: Yes! For a standard 400m track, enter 400 meters and your target pace in seconds per meter.
