Pace Calculator
Use this tool to find your pace per mile, kilometer, or any unit of distance. Whether you’re training for a race or planning a casual run, this calculator helps you track your progress and adjust your speed.
What Is Pace?
Pace is how much time it takes to cover a set distance. It’s usually shown as minutes per kilometer or minutes per mile.
For example:
If you run 5 kilometers in 30 minutes, your pace is 6:00 per kilometer.
How This Calculator Works
You can use the calculator in three ways:
- Find your pace – Enter the time and distance.
- Find your time – Enter the pace and distance.
- Find your distance – Enter the pace and time.
It works for any activity:
🏃 Running · 🚶 Walking · 🚴 Cycling · 🏊 Swimming
Why Pace Matters
Knowing your pace helps you:
- Plan race strategy (marathon, 10K, half marathon)
- Set personal goals
- Avoid starting too fast
- Track improvement over time
- Balance heart rate zones during training
Common Units You Can Use
- Miles
- Kilometers
- Meters
- Yards
- Marathon & Half-Marathon presets
You can also view pace as:
- Minutes per mile / km
- Speed in mph or km/h
Example Pace Calculations
🕒 Example 1: Calculate pace
You run 10K in 55 minutes.
55 ÷ 10 = 5.5 minutes/km → Your pace is 5:30 per km
🏁 Example 2: Estimate race finish time
You want to run a half marathon at 10:00 min/mile.
13.1 × 10 = 131 minutes → 2 hours, 11 minutes
📏 Example 3: Find distance
You run 40 minutes at a pace of 8:00 min/mile.
40 ÷ 8 = 5 miles
Speed vs. Pace
Both are related, but different:
| Concept | Formula | Example |
|---|---|---|
| Pace | Time ÷ Distance | 30 mins ÷ 3 miles = 10 min/mile |
| Speed | Distance ÷ Time | 3 miles ÷ 30 mins = 6 mph |
Training with Pace and Heart Rate
Your pace often matches your heart rate zone:
- Easy pace = Fat-burning zone
- Tempo pace = Improves endurance
- Race pace = Close to anaerobic threshold
Keeping track of both helps prevent overtraining and improve performance over time.
