Which Calculator Do I Need?
Pace Calculator
You finished a run and want to know your pace per mile or per kilometer. Enter your distance and total time.
Example: You ran 5K in 28:30. Your pace is 5:42/km or 9:10/mi.
Speed Calculator
You want to know your speed in mph or kph. Useful for treadmill comparisons or cycling cross-training.
Example: You ran 3 miles in 27 minutes. Your speed is 6.67 mph.
Distance Calculator
You ran for a set time at a known pace and want to find how far you went. Common for timed runs or treadmill sessions without distance tracking.
Example: You ran at 9:00/mi pace for 45 minutes. You covered 5.0 miles.
Finish Time Calculator
You have a race coming up and want to know your expected finish time based on your current pace.
Example: At a 10:00/mi pace, a half marathon takes 2:11:11.
Calorie Calculator
You want to estimate how many calories you burned on a run. Uses the standard MET formula based on body weight and distance.
Example: A 68 kg runner burns about 338 calories on a 5K.
Race Predictor
You want to predict your finish time for a race you have not run yet, based on a recent result at a different distance.
Example: A 25:00 5K predicts roughly a 52:00 10K and a 1:55 half marathon.
How These Calculations Work
The pace, speed, distance, and time calculators use basic arithmetic. Pace equals time divided by distance. Speed equals distance divided by time (in hours). Distance equals time divided by pace. Time equals distance multiplied by pace. All four are variations of the same relationship.
The calorie calculator uses the formula: calories = body weight (kg) x distance (km) x 1.036. This approximation comes from metabolic equivalent (MET) research and is accurate within about 10 percent for most runners at moderate paces.
The race predictor uses the Riegel formula: T2 = T1 x (D2/D1)^1.06, where T1 is your known time, D1 is the known distance, and D2 is the target distance. The exponent 1.06 accounts for the fact that your average pace slows slightly as distance increases. This formula is most accurate for distances between 1 mile and the half marathon. For full marathon predictions, consider adding 3 to 5 percent to account for the "wall" effect.
Turn Numbers Into Territory
Calculators give you the numbers. Motera gives you the motivation to create them. Every run captures real territory on a map, reveals hidden areas through Fog of War, and earns you XP on leaderboards. Free GPS tracking with pace, distance, and time built in.

Frequently Asked Questions
What is a running calculator?
A running calculator is a tool that computes values like pace, speed, distance, time, or calories based on the data you provide. Instead of doing math manually, you enter two values and the calculator gives you the third. For example, enter your distance and time to get your pace, or enter your pace and time to find how far you ran.
How do I calculate my running pace?
Divide your total running time by the distance you ran. For example, if you ran 5 kilometers in 30 minutes, your pace is 30 divided by 5, which equals 6:00 per kilometer. In miles, that same run would be 3.11 miles in 30 minutes, giving you a pace of about 9:39 per mile.
How do I convert running pace to speed?
To convert pace (minutes per mile) to speed (miles per hour), divide 60 by your pace in minutes. For example, if your pace is 10:00 per mile, your speed is 60 divided by 10, which equals 6.0 mph. For kilometers, divide 60 by your pace in minutes per km to get kph.
How many calories does running burn per mile?
A rough estimate is 80 to 120 calories per mile, depending on your body weight. A commonly used formula is: calories = body weight in kg x distance in km x 1.036. A 150-pound (68 kg) runner burns approximately 100 calories per mile or 62 calories per kilometer.
How accurate are race time predictions?
Race predictions using the Riegel formula are generally accurate within 2 to 5 percent for distances up to the half marathon. Predictions for the full marathon tend to be more optimistic because of factors like glycogen depletion and the "wall" effect. For the best marathon predictions, use the Cameron formula or add 5 to 10 percent to the Riegel estimate.
What is a good running pace for beginners?
A good beginner running pace is between 10:00 and 13:00 per mile (6:13 to 8:05 per kilometer). The most important thing is to run at a pace where you can hold a conversation. If you are gasping, slow down. Speed improves naturally with consistent training.
Should I track pace or speed when running?
Most runners track pace (minutes per mile or km) because it makes it easier to plan race splits and training zones. Speed (mph or kph) is more common in cycling and treadmill settings. Both measure the same thing from different angles. Use whichever feels more intuitive to you.
How do I use a running calculator for race planning?
Enter your goal race distance and your target finish time into the pace calculator to find out what pace you need to hold. Then use the race predictor to check whether that target is realistic based on a recent shorter race result. This gives you both the pace and the confidence level for your goal.
