Running Pace Calculator – Track Speed, Time & Distance
Calculate your running pace, speed, and time with our free Running Pace Calculator. Plan your training and reach your running or marathon goals easily.
Understanding Running Pace
Running pace is the time it takes to cover a set distance — typically expressed as minutes per kilometer or minutes per mile. Knowing your pace helps you plan training runs, set race goals, and avoid starting too fast or too slow.
This calculator works three ways: enter any two of distance, time, and pace to find the third. It also converts between km and mile paces and shows your speed in km/h and mph.

From time and paceHow to Use This Calculator
- Calculate Pace: Enter your distance and finish time to find your pace per km and per mile, plus speed
- Calculate Time: Enter a distance and target pace to estimate your finish time
- Calculate Distance: Enter your run time and pace to find how far you went
Common Use Cases
- Race goal setting: Find the pace needed to finish a 5K, 10K, half marathon, or marathon in your target time
- Training runs: Calculate your easy run, tempo, and interval paces for structured training plans
- Post-run analysis: Enter your distance and time to see your actual pace and speed
- Treadmill conversion: Convert treadmill speed (km/h) to outdoor pace (min/km) for comparison
- Relay planning: Calculate how far each runner covers at a given pace within a time window
- Progress tracking: Compare your pace over weeks and months to measure improvement

FAQ – Running Pace Calculator
What is running pace?
Running pace is the time it takes to cover one kilometer or one mile. For example, a 5:30/km pace means you run each kilometer in 5 minutes and 30 seconds. Pace is the inverse of speed — a faster pace means a lower number.
How do I convert pace from km to miles?
Multiply your per-km pace by 1.60934 to get per-mile pace. For example, 5:00/km equals approximately 8:03/mile. This calculator automatically shows both conversions.
What is a good running pace for beginners?
Most beginners run at 7:00–8:30 per km (11:00–14:00 per mile). The key is to start at a comfortable conversational pace where you can talk while running, then gradually increase speed over weeks of consistent training.
How can I improve my running pace?
Incorporate interval training (alternating fast and slow segments), tempo runs (sustained effort at threshold pace), and long slow runs for endurance. Consistency, proper rest, and gradual progression are more important than any single workout.
What is negative splitting?
Negative splitting means running the second half of a race faster than the first half. It's considered the optimal race strategy because it prevents early fatigue and allows you to finish strong. Aim to start 10–15 seconds per km slower than your target pace.
Should I train by pace or heart rate?
Both have value. Pace training is great for race-specific preparation and speed work. Heart rate training ensures you're working at the right intensity regardless of conditions like heat, hills, or fatigue. Many runners use a combination of both methods.
How does elevation affect my pace?
Uphill running typically slows pace by 15–30 seconds per km for every 100m of elevation gain. Downhill running can speed up pace but increases impact stress. On hilly courses, focus on effort level rather than maintaining a constant pace.
What pace should I run a marathon at?
Your marathon pace should be about 30–60 seconds per km slower than your 10K pace. A common approach is to run a recent half marathon and add 10–20 seconds per km. Start conservatively — most marathon failures come from going out too fast.
