How Fast Am I Running In Mph

Running is a great way to stay fit and healthy, and it’s no surprise that many people wonder just how fast they are running in miles per hour (mph). As a runner myself, I’ve often pondered this question and wanted to share some insights and calculations with you.

The Basics of Running Speed

Before we dive into the details, let’s first understand the basic concept of running speed. When we talk about speed, we are referring to how quickly we cover a certain distance. In the case of running, this distance is typically measured in miles or kilometers, and the time is measured in hours or minutes.

Running speed can be calculated using a simple formula: Speed = Distance / Time. For example, if you run 5 miles in 1 hour, your speed would be 5 miles per hour. But how can we determine our running speed in mph during a run?

Using a GPS Watch or Phone App

One of the easiest ways to determine your running speed in mph is by using a GPS watch or a smartphone app with GPS capabilities. These devices use satellite signals to accurately track your distance and speed in real-time. Simply start the app or watch before your run, and it will provide you with your current pace, distance, and speed.

Keep in mind that your running speed may vary throughout your run, depending on factors such as terrain, elevation, and fatigue. It’s important to note that GPS-based speed measurements can sometimes have slight inaccuracies, but they are generally reliable enough for most runners.

Calculating Speed Using Time and Distance

If you don’t have access to a GPS watch or smartphone app, you can still calculate your running speed in mph using the tried-and-true method of time and distance. Here’s how:

  1. Measure your running distance using a known route or a mapping website like Google Maps.
  2. Time yourself while running the measured distance. You can use a stopwatch, a timer on your phone, or even a regular clock.
  3. Convert your time to hours. For example, if you ran for 30 minutes, divide that by 60 to get 0.5 hours.
  4. Divide the distance you measured by the time in hours. For example, if you ran 3 miles in 0.5 hours, your speed would be 6 miles per hour.

Remember, this method provides an approximation of your running speed and may not be as accurate as using a GPS device. However, it can still give you a good idea of how fast you’re running.

Factors That Affect Running Speed

Your running speed can be influenced by several factors, including:

  • Training: Regular training can improve your speed and endurance over time.
  • Running Terrain: Uphill or downhill surfaces can impact your speed.
  • Weather Conditions: Wind, heat, and humidity can affect your running performance.
  • Fitness Level: Your overall fitness plays a role in your running speed.
  • Motivation and Mental Focus: Your mindset can impact your running speed and performance.


Knowing your running speed in mph can be helpful in tracking your progress, setting goals, and improving your overall performance. Whether you use a GPS device or calculate it manually, understanding your running speed adds an extra dimension to your training and makes your running experience more fulfilling.

So lace up your running shoes, hit the pavement, and take a moment to appreciate the thrill of running at your own speed. And remember, it’s not just about how fast you run, but the joy and satisfaction you get from every stride.
