What is Pace Calculator?

Enter your distance and finish time to calculate your average pace per kilometer or per mile. You can also work in reverse by entering a target pace and distance to predict your finish time. The calculator supports common race distances and converts between pace and speed for running, walking, and cycling.

An online tool for runners, walkers, and cyclists that computes pace, speed, and projected finish times. It handles any distance from a 1K fun run to a full marathon and works in both metric and imperial units. The calculator splits your total time into per-unit pace and converts it to average speed in kilometers or miles per hour.

How to Use This Tool
Step-by-step guide to get the best results
1

3

View Your Pace

The calculator displays your average pace per kilometer and per mile, plus your average speed.

Pro Tips
1

For even pacing in races, aim to run the second half within 1 to 2 percent of your first half time rather than slowing significantly.

2

Use your easy run pace, which is typically 60 to 90 seconds slower per mile than your 5K race pace, for most weekly training volume.

3

Track your pace on hilly routes by effort rather than raw numbers, since uphill segments will naturally slow you down.

4

Warm up for 10 to 15 minutes at a conversational pace before starting any timed workout or race.

Frequently Asked Questions
What is a good running pace for beginners?

A comfortable beginner pace is typically between 7 and 9 minutes per kilometer or 11 and 15 minutes per mile. The key is to run at a pace where you can hold a conversation. Speed improves naturally with consistent training over time.

How do I calculate pace for a treadmill run?

Set the treadmill to your desired speed in km/h or mph and the calculator converts it to pace per kilometer or mile. Alternatively, enter your treadmill distance and time to find your average pace for the session.

What is the difference between pace and speed?

Pace measures time per unit of distance, such as 5 minutes per kilometer. Speed measures distance per unit of time, such as 12 kilometers per hour. They express the same information in inverse formats. This calculator converts between both.

How do negative splits improve race times?

Running the second half of a race faster than the first half, called negative splits, conserves energy early when you are fresh and allows you to push harder in the final miles. Most world records have been set with negative or even splits.

Can I use this for walking pace?

Yes, the calculator works for any activity measured by distance and time including walking, hiking, swimming, and rowing. Just enter your distance and time to get your average pace.
