Running Pace Calculator
Predict Race Times for Any Distance
Running Pace Calculator & Race Time Predictor
The Injury Prevention Project’s calculator helps you determine accurate training paces and predict finish times for races of any distance. Whether you’re training for a marathon, half marathon, 10K, or track event, simply enter your goal time for one distance to see equivalent performances across all distances. Our calculator uses the Riegel formula, a well-established method that accounts for how pace naturally changes with distance. Use these predictions to set realistic race goals, plan your training paces, and track your progress. Perfect for runners of all levels looking to optimize their training and race performance.
