Eliminate the Guesswork from Your Pacing

Every runner knows that consistent pacing is the key to a personal best. Whether you are a high school athlete trying to break 18:00 in the 5K or a marathoner aiming for a Boston Qualifier, knowing exactly what splits you need to hit is the first step toward achieving your goal.

This tool acts as a dynamic Pace Chart Generator. Simply enter your target pace per mile, and it will instantly calculate your projected finish time for every major race distance from the 3000m to the Marathon.

Common Ways to Use This Tool:

  • Goal Setting: Enter your “dream 5K pace.”
  • Workout Planning: If you run a tempo run at 6:45/mile pace, use this to see what 10K time that equates to.
  • Race Strategy: Calculate the specific pace you need to hold to break specific barriers (e.g., a sub-3 hour marathon).
