1. What is the Triathlon Race Pace Predictor?

The Triathlon Race Pace Predictor estimates your race time for a new distance based on your performance at a reference distance. It uses a power-law relationship between distance and time that accounts for fatigue at longer distances.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( T_{new} \) — Predicted time for new distance (minutes)
• \( T_{ref} \) — Your known time for reference distance (minutes)
• \( D_{new} \) — New race distance (miles or km)
• \( D_{ref} \) — Reference race distance (miles or km)
• \( k \) — Exponent (typically ≈1.06 for triathlons)

Explanation: The exponent k accounts for the fact that pace slows non-linearly as distance increases due to accumulated fatigue.

3. Importance of Pace Prediction

Details: Accurate pace prediction helps triathletes plan race strategy, set realistic goals, and pace themselves effectively during longer events.

4. Using the Calculator

Tips: Enter your time for a known distance, both distances (use consistent units - both miles or both km), and the exponent. The default exponent of 1.06 works well for most triathletes.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical value for the exponent k?
A: For triathlons, k ≈ 1.06 is common. For running-only events, k ≈ 1.07-1.15 is typical depending on distance.

Q2: How accurate is this prediction?
A: It provides a reasonable estimate but actual performance depends on training, course difficulty, weather, and race conditions.

Q3: Can I use this for individual disciplines?
A: Yes, but use discipline-specific exponents: swim (≈1.02), bike (≈1.04), run (≈1.07).

Q4: Does this work for very different distances?
A: Predictions are most accurate when the new distance is within 50-200% of the reference distance.

Q5: How should I adjust for hilly courses?
A: For hilly courses, add 5-15% to the predicted time depending on elevation gain.
