Today, we embark on a journey to unravel the mystery of one of the most burning questions in the world of fitness – how many calories do we really burn when we hit the pavement for a thrilling run? Caloric expenditure knowledge can help in optimizing our training, proper fueling, and achieving our fitness goals. So, let’s lace up our running shoes and delve into the science behind calculating the calories burned while running.
Understanding Caloric Expenditure
Before diving into the nitty-gritty of running calorie calculation, let’s grasp the concept of caloric expenditure. Our bodies require energy to perform any physical activity, and this energy is measured in calories. The number of calories burned during exercise is influenced by various factors, such as body weight, speed, distance covered, terrain, and running efficiency.
Understanding MET -Metabolic Equivalent of Task
Metabolic Equivalent of Task (MET) is a unit used to estimate the energy expenditure of various activities, including running. It measures the rate of energy expended during an activity compared to the rate at rest. One MET is equivalent to the energy expenditure at rest, which is roughly 1 kcal per kilogram of body weight per hour. MET values for different activities enable us to gauge the intensity of our workouts and accurately calculate the calories burned during physical endeavors. This knowledge empowers us to tailor our training, set realistic fitness goals, and make informed decisions about our exercise routines.
Using MET to Calculate Calories Burned While Running
The MET value for running can vary based on the intensity of your run. Here are some general MET values for different running activities:
- Light jogging (5.0 mph or 8.0 km/h): 6 METs
- Running (6.0 mph or 9.7 km/h): 8 METs
- Running (7.0 mph or 11.3 km/h): 10 METs
- Running (8.0 mph or 12.9 km/h): 11.5 METs
- Running (9.0 mph or 14.5 km/h): 12.8 METs
To calculate the calories burned during your running session, follow these steps:
-
- Determine the MET value of your running activity based on your speed.
- Know your body weight in kilograms.
- Calculate the duration of your run in hours (e.g., 30 minutes is 0.5 hours).
Once you have these values, use the following formula:
-
- Calories Burned = MET x Body Weight (kg) x Duration of Running (hours)
- For example, if you weigh 65 kilograms and run at a pace of 8.0 mph for 45 minutes (0.75 hours):
- Calories Burned = 11.5 METs x 65 kg x 0.75 hours = 563.625 kcal
Using MET to calculate calories burned during running provides a useful estimation of your energy expenditure. However, keep in mind that individual factors can influence the actual calorie burn.
Factors Affecting Caloric Expenditure During Running
Body Weight: Higher weight individuals tend to burn more calories while running as it requires more energy to move a larger mass.
Intensity and Speed: Running uphill generally increases caloric expenditure as your body works harder. Speed plays a factor as you can cover more distance the faster you run.
Terrain: Running on uneven terrain or trails demands more effort, leading to higher calorie burn.
Efficiency: Experienced runners who have better running form and technique might burn slightly fewer calories due to improved efficiency.
Wind Resistance: Running against strong winds can increase calorie burn as it creates additional resistance.
Temperature: Running in extreme heat or cold can elevate calorie expenditure as your body works to regulate its temperature.
Using Fitness Trackers and Apps
In the digital age, we are fortunate to have access to various fitness trackers and mobile applications that can estimate calorie burn based on data inputs like distance, time, and body weight. While these tools provide a good estimate, remember that they might not be 100% accurate as individual variations can play a role.
MapMy Fitness: Developed by Under Armour, MapMy Fitness offers the MapMyRun app, which is designed specifically for runners. It utilizes GPS to track your runs and provides an estimate of the calories burned during your workouts. The app also offers various training plans and workout insights to enhance your running experience.
Fitbit: Fitbit offers a range of fitness trackers and smartwatches equipped with advanced sensors to track your running activities and estimate calorie burn accurately. The Fitbit app syncs seamlessly with the devices, providing detailed insights into your performance.
Apple Watch: The Apple Watch, paired with the built-in Workout app or third-party running apps like Nike Run Club or Strava, is an excellent option for monitoring your runs and calculating your calorie expenditure.
Garmin Connect: Garmin’s range of GPS-enabled running watches, such as the Forerunner and Fenix series, are designed to track your runs with precision. The Garmin Connect app provides comprehensive data, including an estimate of the calories burned during your workouts.
Strava: Strava is a popular social fitness app that allows you to track your runs and connect with a community of runners. It uses GPS data to estimate your calorie burn, making it a valuable tool for those seeking to monitor their running performance.
There are also online calculators like the one below that you can use:
As always, keep in mind that while these fitness trackers and apps can be helpful tools, individual variations and other factors can influence the accuracy of calorie burn calculations.
Understanding how many calories you burn while running is a crucial step in tailoring your training, whether you’re looking to loose weight or optimize your performance. By factoring in variables such as body weight, intensity, and terrain, you can get a reasonable estimate of your caloric expenditure. Embrace the data but listen to your body, as the joy of running goes beyond mere numbers.

Running the Austin International Half means gearing up for a unique, mostly downhill course that has become famous for its speed-friendly layout and scenic views. One way to fully capitalize on that downhill advantage is to master the art of “running the tangent.” If you’re new to this concept, don’t worry—we’ll break it down for you so that you’re prepared to slice seconds off your time while keeping your run as efficient as possible.
What is Running the Tangent?
When runners talk about “running the tangent,” they mean following the shortest possible path along a course, especially around curves or turns. On a curving course, the tangent is the line that cuts directly from one point to another in the straightest possible line, minimizing the distance you need to cover.
Think of it like driving around a corner—you wouldn’t take the widest route if you were looking to get somewhere faster. Instead, you’d follow the inside line to reach your destination quicker. By running the tangent in a race, you’re applying the same principle to keep your mileage to a minimum while maintaining an efficient pace. Our course is officially certified using these tangents, meaning every turn and stretch is measured to ensure you’re running the shortest possible distance to that finish line!
Why Tangents Matter on a Mostly Downhill Course
The Austin International Half racecourse is known for being fast, largely because it trends downhill. A course like this offers you two primary benefits:
1. Free Speed: Downhills naturally propel you forward with gravity’s help, meaning you can save energy while maintaining a quicker pace.
2. Momentum Preservation: Running the tangent on downhill stretches helps you avoid wasting that precious momentum by veering too wide.
Every extra step adds time, so staying efficient and direct not only keeps you fast, but also helps conserve energy over the 13.1 miles.
Tips for Running the Tangent
Now that you know why it’s important, here’s how to run the tangent like a seasoned pro on race day:
1. Know the Course
Familiarize yourself with Austin’s course map ahead of time. While you don’t need to memorize every twist and turn, get a general sense of where curves and major turns happen. Understanding the course will allow you to anticipate where tangents can save you the most time.
2. Visualize the Tangent Line
When approaching a curve, imagine a straight line connecting the beginning of the turn to its end. This line will be the shortest distance through that section. Adjust your positioning on the road to follow this imaginary line, especially when the route dips downhill. That way, you’re making gravity work for you.
3. Stay Aware of Other Runners
While running the tangent is efficient, remember that you’re sharing the course. Look ahead to see where you can safely line up with the tangent without crowding or cutting off other runners. Be courteous and strategic—finding an open path on the inside of a curve can give you an edge without disrupting the flow.
4. Plan Your Strategy for Downhills
Downhill running, especially on tangents, can feel intense. Let gravity pull you, but stay controlled by leaning slightly forward and keeping your strides quick and light. Focus on the tangent line to stay balanced and maximize your descent.
5. Use Landmarks as Guides
The course is loaded with visual markers, from skyline views to popular street names. Pick a landmark at the end of each curve or turn as a point to aim for. This will help you naturally align with the tangent without needing to constantly look down or adjust your path.
Benefits Beyond the Finish Line
Training to run tangents does more than save you time on race day. It improves your awareness and pacing, teaching you to run with more precision. By practicing tangent-running in your training, you’ll develop a natural instinct for efficient movement—an asset on any course.
Hitting Your PR—and the Gong!
This race is famous for helping runners hit personal records (PRs), thanks to its downhill speed and course design. If you break your record, make sure to celebrate by heading over to the PR Gong post-race—smash it and share the triumph with everyone around!
Final Thoughts: Get the Most Out of Every Mile
Running tangents may seem like a small detail, but when you’re pushing for your best time, it all adds up. Austin International Half’s fast, downhill course offers the perfect setting to test this skill. Practice the art of the tangent, keep your race-day mindset sharp, and trust in your training. You’re setting yourself up not just to finish, but to finish strong.
So lace up, hit the road, and prepare to run tangents like a pro!
