What Is a Good 5K Run Time?
A "good" 5K time is relative to your age, gender, and how long you have been running. The chart below shows average 5K times by age group. If you are faster than the average for your group, you are doing better than most runners who show up to a typical 5K race.
For context, finishing a 5K under 25 minutes puts you in roughly the top 30% of all male finishers. For women, finishing under 28 minutes achieves the same percentile. Breaking 20 minutes (men) or 23 minutes (women) puts you in the top 10% of recreational racers.
The most important benchmark is your own previous time. A 35 minute runner who improves to 32 minutes has made excellent progress regardless of where that falls on a population chart. Focus on consistent training and the times will follow.

How to Use This 5K Run Time Calculator
This calculator is built specifically for the 5K distance and covers the four most common questions runners have. The Pace to Time tab takes your current running pace (per mile or per kilometer) and calculates your exact 5K finish time. It also shows the equivalent pace in the other unit, so you can easily switch between miles and kilometers.
The Time to Pace tab works in the opposite direction. Enter a target 5K time and the calculator shows you the pace per mile and per kilometer you need to hold. This is especially useful when setting a race goal. For example, entering 25:00 tells you that you need to run 8:03 per mile consistently.
The Predict tab uses the Riegel formula to estimate your 5K potential from either a recent mile time trial or a 10K race result. Predictions from a 10K tend to be very accurate because the distances are close. Predictions from a mile can be optimistic if you have not trained for the full 5K distance.
The Treadmill tab converts any treadmill speed (in mph or kph) into a 5K finish time and pace. This is perfect for treadmill runners who want to know what their display speed translates to in race terms. For more detailed pace tools, check our 5K pace calculator or the full 5K running times chart.

MoteraFrequently Asked Questions
What is a good 5K run time?
A good 5K time depends on your age, gender, and experience. For men, a 5K under 25 minutes is considered above average, under 20 minutes is competitive, and under 17 minutes is advanced. For women, under 28 minutes is above average, under 23 minutes is competitive, and under 19 minutes is advanced. Any time that represents an improvement over your previous best is a good time.
How do I calculate my 5K run time from pace?
Multiply your pace per mile by 3.107 (the number of miles in a 5K). For example, if you run 8:00 per mile, your 5K time would be 8 multiplied by 3.107, which equals approximately 24:51. If you use pace per kilometer, multiply by 5. An 8:00 per mile pace equals roughly 4:58 per kilometer, so 4:58 multiplied by 5 gives you about 24:51.
Can I predict my 5K time from a mile time?
Yes. The Riegel formula predicts 5K time from a mile time using the equation: 5K time = mile time multiplied by (5 / 1.60934) raised to the power of 1.06. For example, a 7:00 mile predicts roughly a 23:30 5K. This assumes you are trained for the 5K distance. If you only run short distances, the prediction may be optimistic by 1 to 3 minutes.
How do I convert treadmill speed to 5K time?
Divide 3.107 miles by your treadmill speed in mph, then multiply by 60 to get minutes. For example, at 7.0 mph: 3.107 divided by 7.0 equals 0.4438 hours, multiplied by 60 equals 26:38. For kph, divide 5 km by your speed. At 11.0 kph: 5 divided by 11.0 equals 0.4545 hours, multiplied by 60 equals 27:16. Note that treadmill times may be slightly faster than outdoor times due to the lack of wind resistance and terrain changes.
How long does it take a beginner to run a 5K?
Most beginners finish their first 5K in 30 to 40 minutes. If you follow a Couch to 5K program, you can typically go from zero running to completing a 5K in 8 to 10 weeks. Your first goal should simply be to finish the distance. Speed improvements come naturally with consistent training over the following months.
What is the average 5K time?
The average 5K finish time across all age groups is approximately 27:21 for men and 30:45 for women, based on aggregated race data from the United States. These numbers include runners of all abilities, from first timers to experienced competitors. The median tends to be slightly faster than the mean because of the long tail of slower finishers.
How do I get my 5K time under 20 minutes?
A sub 20 minute 5K requires averaging 6:26 per mile (4:00 per km). To reach this level, most runners need to train 4 to 6 days per week with a mix of easy runs (80% of volume), interval sessions (such as 6 to 8 x 800m at 5K pace), and tempo runs at half marathon pace. Consistency over 6 to 12 months is more important than any single workout.
Is a 5K on a treadmill easier than outdoors?
Running on a treadmill is generally considered slightly easier than running outdoors at the same pace. The treadmill belt assists leg turnover, there is no wind resistance, and the surface is perfectly flat. Setting the treadmill to a 1% incline is a common recommendation to approximate outdoor effort. However, some runners find treadmill running mentally harder because of the lack of changing scenery.
