About the Pace Calculator
What is the Pace Calculator?
A pace calculator converts a distance and a time into your running or cycling pace and average speed.
Why use this calculator?
Training to a target pace is one of the most reliable ways to run a race on plan, and pacing yourself prevents burning out early.
How to use it
- Enter the distance and choose km or miles.
- Enter the time as hours, minutes and seconds.
- Read your pace per unit and your average speed.
Formula
Pace = total time ÷ distance; speed = distance ÷ time.
Good for flat road sessions. Elevation, wind and terrain all change the real effort required.
Frequently Asked Questions
What is a good running pace?
It depends on experience and age. A common benchmark is sub-8:00 per mile for a 5K, but the best pace is the one that matches your training plan.
Should I run by pace or heart rate?
Pace works well on flat routes in good conditions. Heart rate adapts to hills, heat and fatigue, so many runners combine both.
Is this a medical diagnosis?
No. This tool provides general wellness information only. It is not a substitute for evaluation by a qualified healthcare professional.
Why do results differ from my doctor's measurements?
Clinical measurements use calibrated equipment and professional technique. Home estimates rely on formulas and self-reported values, so small differences are normal.
How often should I recalculate?
Recheck after meaningful changes such as weight gain or loss, a new workout routine, or every few months to track trends over time.
Do these formulas apply to everyone?
Most population formulas are less accurate for athletes, pregnant people, very young children and the elderly. Use them as a general guide.
Is this calculator free to use?
Yes. Every calculator on this site is completely free, with no hidden fees, no subscriptions and no limits on how many times you can use it.
How accurate are the results?
We use standard, widely accepted formulas and calculate in your browser using double-precision arithmetic. Results are rounded for readability, so treat them as reliable estimates rather than a guarantee. Real-world factors can vary the true figure.
Can I add this calculator to my own website?
