Instructions and Notes:

  1. Input 5K time in "mm:ss" format.
  2. Volume inputs should be determined by taking an average of your six highest training weeks during the previous ten weeks leading up to the race being estimated.
  3. Years of experience should be determined by the number of seasons in which you have raced at the distance being estimated, not including this year.
  4. Minimum run training volume = 5 miles.
  5. The calculator is currently calibrated to give an individual's "best scenario" race time on an average course. Any nutrition mistakes, injuries or mishaps will reduce the likelihood of achieving the calculated race time.
  6. Questions about the calculator? Or if you have a specific race that you would like estimated for pacing purposes, please contact: Jesse at [email protected]
