1. What is Threshold Run Pace?

Threshold run pace is the pace you can sustain for about an hour of racing (typically 85-90% of maximum effort). It's a key metric for runners to determine appropriate training intensities and predict race performance.

2. How Does the Calculator Work?

The calculator uses the threshold pace formula:

Where:

• \( P \) — Pace (minutes per mile)
• \( T \) — Time (minutes)
• \( D \) — Distance (miles)

Explanation: The equation calculates your average pace by dividing your total running time by the distance covered.

3. Importance of Threshold Pace

Details: Knowing your threshold pace helps structure training sessions, determine appropriate workout intensities, and track fitness improvements over time.

4. Using the Calculator

Tips: Enter your time in minutes and distance in miles. The values should come from a recent hard effort (about 1 hour duration) for most accurate threshold pace estimation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between threshold pace and race pace?
A: Threshold pace is typically slightly slower than 10K race pace and faster than half-marathon pace. It's the pace you could sustain for about an hour of racing.

Q2: How often should I test my threshold pace?
A: Every 4-6 weeks is typical to track progress. Testing too frequently may not show meaningful changes.

Q3: Can I use kilometers instead of miles?
A: Yes, but be consistent - use kilometers for both distance and pace (min/km). The calculator currently uses miles.

Q4: What if my effort wasn't exactly one hour?
A: The calculator works for any duration, but threshold pace is most accurate when calculated from efforts between 45-60 minutes.

Q5: How should I use threshold pace in training?
A: Threshold pace is ideal for tempo runs and cruise intervals. Most runners can sustain this pace for 20-40 minutes in training.
