Race Time Prediction Formula:
| From: | To: |
The Running Race Time Predictor estimates your potential race time at a new distance based on your performance at a known distance. It uses a mathematical model that accounts for the non-linear relationship between distance and running time.
The calculator uses the following equation:
Where:
Explanation: The exponent 1.06 accounts for the fact that running speed decreases slightly as distance increases, making the relationship non-linear.
Details: Accurate race time prediction helps runners set appropriate pace goals, plan training schedules, and set realistic expectations for race performance.
Tips: Enter your best time for a known distance, the distance itself, and the target distance you want to predict. All values must be positive numbers.
Q1: How accurate is this prediction?
A: The prediction is generally good for runners with consistent training, but actual performance depends on many factors including course difficulty and weather.
Q2: What distances work best for prediction?
A: The prediction works best when the known and target distances are relatively close (e.g., 5K to 10K) rather than very different (e.g., 5K to marathon).
Q3: Does this account for terrain differences?
A: No, the calculator assumes similar terrain conditions for both races. Adjust predictions for significant elevation changes.
Q4: Can I use kilometers instead of miles?
A: The calculator currently uses miles, but you can convert kilometers to miles (1 km = 0.621371 miles) before entering values.
Q5: Why is the exponent 1.06?
A: Research has shown this exponent provides the best fit for most runners' performance across different distances.
