Pace
Running Pace
Running pace is the time it takes to cover a set distance, typically expressed as minutes per mile or kilometer. Learn how pace works and how to use it for training and racing.
Quick Answer
Pace — Running pace is the time it takes to run a specific distance, typically expressed as minutes per mile (min/mi) or minutes per kilometer (min/km). For example, an 8:00 min/mi pace means you complete each mile in 8 minutes.
What Does Pace Mean?
Pace is the inverse of speed. While speed measures distance per time (mph, km/h), pace measures time per distance (min/mi, min/km).
Pace Formula:
Pace = Time / Distance
Example: Running 5 km in 25 minutes:
Pace = 25 min / 5 km = 5:00 min/km

Why Runners Use Pace
| Advantage | Why It Matters |
|---|---|
| Intuitive pacing | Easy to maintain consistent effort |
| Training prescription | Zones defined by pace ranges |
| Race planning | Calculate splits and finish times |
| Progress tracking | Compare paces over time |
Unlike cyclists who use watts, runners rely on pace because:
- Running power meters are less common
- Pace is easier to check mid-run
- Most races use pace-based splits

Min/Mile to Min/Km
Min/km = Min/mile × 0.6214
| Min/Mile | Min/Km | Speed (mph) | Speed (km/h) |
|---|---|---|---|
| 6:00 | 3:44 | 10.0 | 16.1 |
| 7:00 | 4:21 | 8.6 | 13.8 |
| 8:00 | 4:58 | 7.5 | 12.1 |
| 9:00 | 5:35 | 6.7 | 10.7 |
| 10:00 | 6:13 | 6.0 | 9.7 |
Pace Zones for Training
Running paces are typically divided into training zones:
| Zone | Name | Purpose | Example (8:00/mi racer) |
|---|---|---|---|
| Easy | Recovery/Easy | Aerobic base | 9:30-10:30/mi |
| Tempo | Tempo | Lactate threshold | 7:45-8:15/mi |
| Threshold | Threshold | Race pace | 7:30-7:45/mi |
| Interval | VO2 Max | Speed development | 6:45-7:15/mi |
| Repetition | Speed | Neuromuscular | < 6:30/mi |

Pace for Different Distances
Expected Pace by Race Distance
Pace naturally slows over longer distances:
| Distance | Typical Pace Increase |
|---|---|
| 5K | Baseline |
| 10K | +15-25 sec/mile |
| Half Marathon | +30-45 sec/mile |
| Marathon | +45-75 sec/mile |

| 30:00 | 9:58/mi | 10:33/mi | 11:00/mi |
Pacing Strategies
Even Pacing
Running consistent splits throughout the race. Best for:
- Flat courses
- Experienced runners
- Time-goal races
Negative Split
Running the second half faster than the first. See Negative Split.
Positive Split
Running the second half slower. Common in:
- Marathons (fatigue)
- Hilly courses
- Hot conditions

Factors Affecting Pace
Environmental Factors
| Factor | Effect on Pace |
|---|---|
| Heat (>60°F/15°C) | Slows 1-3% per 10°F |
| Humidity | Adds to heat effect |
| Altitude | Slows 3-5% per 5000ft |
| Wind | Significant on exposed courses |
| Hills | Varies by gradient |
See our guides on how weather affects running and altitude running.
Physical Factors
| Factor | Effect |
|---|---|
| Fitness | Improved pace with training |
| Fatigue | Accumulated training stress |
| Fueling | Poor nutrition slows pace |
| Hydration | Dehydration impairs performance |
Common Questions
What's a good running pace?
It depends on your goals and experience:
- Recreational jogger: 10-12 min/mile
- Regular runner: 8-10 min/mile
- Competitive amateur: 6-8 min/mile
- Elite: < 5 min/mile
How do I find my easy pace?
Easy pace is typically 60-90 seconds slower than your current 5K race pace. You should be able to hold a conversation comfortably.
Should I run by pace or heart rate?
Both have merit:
- Pace: Objective, easy to track, good for flat terrain
- Heart rate: Accounts for conditions, better for hills/heat
Most coaches recommend learning both methods.
How do I improve my pace?
- Build aerobic base with easy miles
- Include weekly tempo/threshold work
- Add interval sessions for speed
- Increase weekly mileage gradually
- Allow adequate recovery
