Quick Access in Windows File Explorer gives you one-click access to your most-used folders and recent files, so you can skip the folder-by-folder navigation that eats up your day. This article explains what Quick Access is, how to pin and unpin items, how to customize it, and how to fix common problems when it stops working.

Formula

The calculator works out your average pace and speed from two numbers you enter: the time it took to finish and the distance you covered. The formulas are:

  • Pace (min/km) = Finish time (minutes) ÷ Distance (km)
  • Speed (km/h) = Distance (km) ÷ (Finish time (minutes) ÷ 60)

Where Finish time is in minutes, Distance is in kilometers, Pace is in minutes per kilometer, and Speed is in kilometers per hour. If you measure distance in miles, convert to kilometers by multiplying by 1.60934 before using the calculator.

Worked Example

Using the default values from the calculator: finish time = 50 minutes, distance = 10 km.

  1. Pace = 50 ÷ 10 = 5.00 min/km
  2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows an average pace of 5.00 min/km and an average speed of 12.00 km/h. That matches what you would get by hand.

When to Use This Calculator

Use this tool whenever you finish a run, bike ride, walk, or any trip where you know the total time and distance. It is especially handy for training, where you want to track your pace over time, or for planning: if you know your target pace, you can work backward to estimate finish time. The result is an average—it does not show variations in speed during the activity, so it is not a substitute for a GPS watch if you need splits or elevation data.

How to Read the Result

A lower pace (min/km) means you are moving faster. A higher speed (km/h) also means faster. For example, a pace of 6 min/km is slower than 5 min/km, and 10 km/h is slower than 12 km/h. If you are used to miles, convert pace to min/mile by multiplying by 1.60934, and convert speed to mph by dividing by 1.60934. The calculator gives two decimals, which is enough for most training logs.

Common Mistakes and Unit Mix-Ups

  • Forgetting to convert miles to km: If you enter miles as if they were kilometers, your pace will look faster than reality. Always convert to the same unit system.
  • Using hours instead of minutes: The calculator expects minutes. If your time is 1 hour 30 minutes, enter 90, not 1.5.
  • Mixing pace and speed: Pace is time per distance, speed is distance per time. They are inversely related—a high pace number means a low speed number.

Limitations of the Formula

The average pace formula assumes a constant speed over the entire distance. Real-world activities include hills, stops, and changes in effort, so your actual pace at any moment will differ. The formula also does not account for elevation gain, terrain, or weather. For precise training data, use a GPS device or an app that records instantaneous pace. This calculator is best for simple, flat, steady efforts where an average is meaningful.

Frequently Asked Questions

What is a good running pace for a beginner?

There is no single answer because it depends on age, fitness, and experience. A common starting point for a recreational runner is around 6:30 to 8:00 min/km (about 10:30 to 12:50 min/mile). Use the calculator to see what pace you actually maintain, then adjust gradually.

How do I convert min/km to min/mile?

Multiply the pace in min/km by 1.60934. For example, 5:00 min/km becomes 8:03 min/mile. To convert speed from km/h to mph, divide by 1.60934.

Can I use this for walking or cycling?

Yes. The formula works for any activity where you know time and distance. Just enter your walking or cycling time and distance, and the calculator gives your average pace or speed.

Why does the calculator show “Cannot compute”?

That happens when the finish time or distance is zero or negative, or when the distance is larger than the maximum allowed. Check your inputs and make sure the time is positive and the distance is within the allowed range (up to 100,000 km).

Is average pace the same as average speed?

No. Pace is time per unit distance (e.g., minutes per km), while speed is distance per unit time (e.g., km/h). They are reciprocals of each other, so a faster pace corresponds to a higher speed, but the numbers are not directly comparable without conversion.
