Pace Calculator

Calculate running or walking pace from distance and time, or estimate finish time from pace. Supports miles and kilometers.

About the Pace Calculator

Whether you're training for a 5K, marathon, or just tracking your daily walks, knowing your pace is essential. The Pace Calculator converts between three key metrics: pace (minutes per mile or km), speed (mph or km/h), and finish time for any distance.

Pace is the inverse of speed — instead of "how far per hour," it's "how long per mile." Runners and walkers prefer pace because it's more intuitive for planning splits and setting goals. A 10:00 min/mile pace is easy to target with a watch; "6 mph" is harder to feel.

Enter any two of the three values (distance, time, pace) and the calculator solves for the third. You can also use it to plan race strategies: enter your goal marathon time and the calculator tells you the per-mile pace you need to maintain. Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation.

Why Use This Pace Calculator?

Pace is the most practical metric for runners and walkers. It directly tells you how fast to run each mile to hit your goal. This calculator lets you plan training paces, predict race outcomes, and convert between pace and speed for cross-training activities. Having a precise figure at your fingertips empowers better planning and more confident decisions.

How to Use This Calculator

  1. Enter the distance you ran or plan to run in miles.
  2. Enter the total time in minutes.
  3. The calculator automatically computes your pace (min/mi) and speed (mph).
  4. Alternatively, enter pace and distance to calculate total time.
  5. Use the results to plan training splits and race strategies.

Formula

Pace = Total Time ÷ Distance (minutes per mile) Speed = Distance ÷ (Time ÷ 60) (miles per hour) Finish Time = Pace × Distance

Example Calculation

Result: 9:02 min/mi (6.64 mph)

Running a 5K (3.1 miles) in 28 minutes gives a pace of 9 minutes 2 seconds per mile, equivalent to 6.64 mph. This is a solid recreational runner pace for a 5K race.

Tips & Best Practices

Understanding Running Pace

Pace is the fundamental metric for runners because it's actionable during a run. When your watch shows 8:30/mile, you know exactly whether you're on target. Speed numbers like 7.06 mph are harder to feel and adjust in real time.

Common Race Paces

5K (3.1 mi): beginners 30–35 min (10:00–11:00/mi), intermediate 22–28 min (7:00–9:00/mi). 10K: beginners 60–70 min, intermediate 45–55 min. Half marathon: beginners 2:15–2:30, intermediate 1:45–2:00. Marathon: beginners 4:30–5:30, intermediate 3:30–4:15.

Training with Pace Zones

Most training plans use pace zones: easy (60–90 sec slower than race pace), tempo (15–30 sec slower), race pace, and interval (15–30 sec faster). Knowing your race pace helps you set all training zones.

Pace and Weather

Heat slows pace by approximately 1–2% for every 5°F above 60°F. Wind, rain, and humidity also affect performance. Adjust pace expectations for race day conditions.

Frequently Asked Questions

What is a good running pace?

It depends on fitness and goals. Beginner runners average 10:00–12:00 min/mile. Intermediate runners 8:00–10:00. Advanced runners 6:00–8:00. Sub-5:00 is competitive/elite.

How do I convert pace to speed?

Divide 60 by your pace in minutes. A 10:00 min/mile pace = 60 ÷ 10 = 6.0 mph. An 8:30 pace = 60 ÷ 8.5 = 7.06 mph.

What pace do I need for a 4-hour marathon?

A marathon is 26.2 miles. 240 minutes ÷ 26.2 = 9:09 min/mile. You need to maintain just over 9 minutes per mile for the entire distance.

Is pace per kilometer or per mile?

Both are used. In the US, pace is typically in minutes per mile. Internationally, minutes per kilometer is standard. This calculator shows both.

How does elevation affect pace?

Uphill running can slow pace by 30–60 seconds per mile for moderate hills. Downhill gains back some but not all of that time. Adjust expectations for hilly courses.

What's the difference between pace and speed?

Pace is time per distance (e.g., 9 min/mile). Speed is distance per time (e.g., 6.7 mph). They're inversely related. Runners prefer pace; cyclists and drivers prefer speed.
