Running Speed Comparison Table
From walking to elite-level running, here is how speed, pace, and effort level relate. This table helps you understand what different speeds actually feel like and where you fall on the spectrum.
Average Running Speed by Age and Gender
These averages come from analyzing millions of race results across 5K, 10K, and half marathon distances. Your speed will vary based on distance, terrain, weather, and fitness level. These numbers represent typical recreational runners, not competitive athletes.
For a detailed breakdown with percentile rankings, see our average running pace by age guide.
Treadmill Speed to Pace Reference
Treadmills display speed in mph (in the US) or kph (internationally), but most runners think in pace. This table shows you what each treadmill speed setting translates to in minutes per mile and minutes per kilometer.

Speed Zones for Training
Training by speed zones helps you vary your intensity appropriately. The speeds below are general guidelines for recreational runners. Your personal zones will depend on your fitness level. A good starting point is to base Zone 2 on your comfortable conversational pace.
Zone 1: Recovery
3.5 to 5.0 mph / 5.6 to 8.0 kphVery easy effort. You can hold a full conversation. Used for warm-ups, cool-downs, and recovery runs. Should feel almost too easy.
Zone 2: Aerobic Base
5.0 to 6.5 mph / 8.0 to 10.5 kphEasy effort where you can talk comfortably. This is where 80% of your training should happen. Builds the aerobic engine that powers everything else.
Zone 3: Tempo
6.5 to 8.0 mph / 10.5 to 12.9 kphComfortably hard. You can speak in short sentences. Tempo runs at this speed improve your lactate threshold, allowing you to run faster before fatigue sets in.
Zone 4: Threshold
8.0 to 9.5 mph / 12.9 to 15.3 kphHard effort. You can only say a few words at a time. Interval training at this speed improves your VO2max and race-specific fitness. Limit to 1 to 2 sessions per week.
Zone 5: Sprint
9.5+ mph / 15.3+ kphMaximum effort. Speaking is impossible. Used for short intervals (200m to 400m repeats) and race finishes. Improves top-end speed and neuromuscular coordination.
How Fast Am I Running? Speed vs. Pace Explained
If you drive a car, you think in speed: 30 mph, 60 mph. But runners think in pace: 8:00 per mile, 10:00 per mile. These are two ways of expressing the same thing, but they are inversely related. When speed goes up, pace goes down (the number gets smaller because you cover each mile in fewer minutes).
The reason runners prefer pace is practical. When you are training for a race, you need to know how many minutes each mile will take so you can plan your splits and predict your finish time. Saying "I need to run 7:15 per mile for 26.2 miles" is more actionable than "I need to average 8.28 mph for 26.2 miles."
However, speed is more intuitive for many people, especially those who are new to running or who primarily use treadmills (which display speed, not pace). If someone tells you they run at 7 mph, you immediately understand that is faster than 5 mph. But if someone says they run a 8:34 pace, the meaning is less immediately clear unless you are already a runner.
This calculator bridges both worlds. Enter your data in whichever format makes sense to you, and see the result in both speed and pace. Over time, you will develop an intuition for both systems.
Run Faster. Capture More Territory
Motera tracks your speed, distance, and pace on every run while you capture territory on a real map. The faster you run, the more ground you cover, and the more territory you claim. Watch your city transform as you build speed throughout your training.

MoteraFrequently Asked Questions
What is the difference between running speed and pace?
Speed measures how much distance you cover per unit of time (miles per hour or kilometers per hour). Pace measures how long it takes to cover a unit of distance (minutes per mile or minutes per kilometer). They are inversely related: faster speed means lower pace numbers. Most runners use pace for training, but treadmills and casual runners often think in speed.
What is a good running speed for beginners?
A typical beginner running speed is 4.5 to 6.0 mph (7.2 to 9.7 kph), which corresponds to a pace of roughly 10:00 to 13:20 per mile. The most important thing is that you can maintain the speed for your target distance. If you can hold a conversation while running, you are at a good training speed.
How fast is 10 mph running?
Running at 10 mph equals a 6:00 per mile pace (3:44 per km). This is a fast speed that most recreational runners cannot sustain for long distances. For context, a 6:00/mile pace would produce a 5K time of 18:38 and a marathon time of about 2:37. Elite runners sustain speeds of 12 to 13 mph during a marathon.
What speed should I set my treadmill to?
For easy running, most people set the treadmill between 5.0 and 7.0 mph (8.0 to 11.3 kph). For walking, 3.0 to 4.0 mph is typical. For tempo runs, add 1 to 2 mph above your easy pace. Start slower than you think you need to and increase after you warm up. Treadmill running often feels slightly easier than outdoor running because there is no wind resistance.
How do I convert treadmill speed to pace?
Divide 60 by the treadmill speed in mph to get minutes per mile. For example, 6.0 mph equals 60 divided by 6, which is 10:00 per mile. For kilometers, divide 60 by the speed in kph. The speed-to-pace table on this page shows all common conversions.
What is the average human running speed?
The average recreational running speed is about 5 to 6 mph (8 to 9.7 kph) for adults. This varies significantly by age, gender, fitness level, and distance. Sprinters can reach 15 to 28 mph in short bursts, while marathon runners average 6 to 13 mph depending on their level. The fastest recorded human speed is 27.8 mph, set by Usain Bolt.
Does running faster burn more calories?
Yes, running faster burns more calories per minute because your body works harder. However, running slower allows you to run longer, which can result in more total calories burned per session. For weight loss, total distance matters more than speed. A 150-pound person burns roughly 100 calories per mile regardless of speed, so running 5 slow miles burns about the same total as 5 fast miles.
How do I increase my running speed?
The most effective ways to increase running speed are: run more total miles per week at easy effort, include one interval session per week (such as 400m or 800m repeats), add one tempo run per week (20 to 40 minutes at comfortably hard effort), and include strides (short 20 to 30 second accelerations) after easy runs. Keep 80% of your running easy and only push hard on designated workout days.
