Race Predictor Calculator

Estimate how long it will take to run a specified distance, based on a previous race result. This type of predictive analysis is more accurate when the two distances are relatively similar (e.g. 5K and 10K), since runners can not be optimally trained for this entire spectrum of distances from 1 mile to the marathon.

Enter the distance of a previous race using the pull-down menu labeled "Distance Run".

Then enter the time for that race in the input boxes on the right. Leave all "Pace" fields blank.

Select a different distance using the pull-down menu labeled "New Distance" and press "Calculate".
