Race Time Predictor

Want to know how you would do on a 10K race based on your last 5K time? Or what kind of half marathon time would you expect to have?

Our Race Time Predictor calculator will help you to estimate how long it will take you to finish a race of a different distance based on the results of a previous run race. Enter the base distance and your completion time of the race that you want to use as a model.

Remember, this time is only an estimate. All the running is still up to you.
