Race Predictor

Welcome to the Race Time Predictor

Predict Your Race Times

The Race Time Predictor is an advanced tool designed to help runners estimate their performance across various distances. By inputting your recent race time and distance, you can predict your finish times for other races, such as 5K, 10K, half marathon, and marathon. This tool is perfect for setting realistic goals and planning your training strategy.

How It Works

The Race Time Predictor uses the Peter Riegel formula, a widely recognized method for predicting race times based on your performance at a given distance. By adjusting for your speed or endurance preferences, the tool provides accurate predictions tailored to your running style. Additionally, it visualizes your predicted paces with an interactive chart, making it easy to understand your performance across different distances.

Key Features

• Time Input: Input your race time in hours, minutes, and seconds for precise predictions.
• Speed vs Endurance Slider: Adjust the slider to indicate whether you're more speed-oriented (better at shorter distances) or endurance-oriented (better at longer distances). This fine-tunes the predictions to match your running style.
• Predicted Times: Instantly see your predicted finish times for standard race distances, along with your average pace for each.
• Interactive Chart: Visualize your predicted paces with a dynamic D3 chart, showing how your pace changes across different distances.
• Unit System: Switch between metric and imperial units to match your preference.
