Running ​Race Predictor


This simple race pace and finish time calculator uses your recent race results to give you a clear table of your predicted race time for other distances, such as 5km, 10km and half marathon. The calculator also shows your predicted race pace in kms and miles! 

To get the most accurate predictions, it helps if your previous race was similar to your predicted race, in terms of:

  • Weather, 
  • Terrain, and
  • Race flow (minimal bottlenecks/turns etc.).

After using the running calculator, you can also print your results or download as a PDF below. Enjoy!
