How to calculate running pace improvement
This calculator finds running pace improvement percentage by comparing an old pace time to a new pace time.
How the calculation works
Improvement = ((Old pace − New pace) ÷ Old pace) × 100.
Example
An old pace of 9:00/mile improving to 8:15/mile (converting to consistent units, e.g., seconds: 540 to 495): ((540−495)÷540)×100 ≈ 8.3%.

Pro Tips for Running Pace Improvement
- Convert pace times to a single consistent unit (like total seconds) before calculating percentage improvement, since minutes:seconds format can't be used directly in this formula.
- A positive result means pace improved (got faster); if new pace is actually slower, the result will be negative.
Common Running Pace Improvement Mistakes to Avoid
- Using pace values still in minutes:seconds format (like '9:00') directly in the formula without converting to total seconds first, which would produce an incorrect result.
