Running Pace Calculator

Calculate running pace, splits, and finish time predictions for any distance.

Usage

Provide your distance and time, or a target pace, and I'll calculate splits and predictions.

Examples

• "I ran 5K in 25 minutes, what's my pace?"
• "What pace do I need for a sub-4-hour marathon?"
• "Convert my 10K time to a half marathon prediction"

Guidelines

• Pace predictions are estimates based on general fitness correlations
• Hills and weather will affect actual pace
• Train at various paces for best results
• Easy runs should feel conversational
• Race day pace should be practiced in training
