Your Ultimate Guide to Calculating Energy Burn and Fueling Your Austin Marathon Training

 

Are You Really Burning As Many Calories As You Think?A hand holds a sheet of paper labeled "Calories," with one corner burning—flames consuming part of the text—symbolizing how a calories burn calculator tracks your progress. The background is a gray, tiled wall. Austin Marathon Half Marathon & 5K

Did you know that a 10K run could torch up to 800 calories? But how much are you really burning when you hit the pavement for your next training run? Whether you’re aiming to fuel better, recover smarter, or crush your goals at the Austin Marathon, understanding how many calories you burn while running is the key to leveling up your performance.

Understanding Caloric Expenditure: The Basics

When you run, your body burns calories to fuel your muscles, regulate your temperature, and keep you moving. The total calorie burn depends on:
  • Your weight and body composition – the more you weigh, the more energy you burn.
  • Running speed – faster running increases your burn rate.
  • Duration and distance – longer runs burn more calories.
  • Terrain and conditions – hills, trails, and heat (hello, Austin!) can add to your energy cost.
  • Running efficiency – experienced runners may burn fewer calories per mile.

Let’s Crunch the NumbersA person stands with one bare foot on a white bathroom scale, next to a blue exercise mat on a tiled floor, perhaps curious about the running calories or calories burned during their workout.

Calories Burned Per Mile

A general rule of thumb: 100 calories per mile.
  • 120-pound runner: approximately 85 calories per mile
  • 180-pound runner: approximately 125-130 calories per mile
For a 10K (6.2 miles), expect to burn 500–800 calories depending on your weight and pace.

Calories Burned Per Hour

For a 155-pound runner:
  • 5 mph (12-minute mile): approximately 600 calories/hour
  • 6 mph (10-minute mile): approximately 700 calories/hour
  • 7.5 mph (8-minute mile): approximately 850 calories/hour

Using MET to Calculate Calories Burned While Running

Want a more accurate estimate? Use MET (Metabolic Equivalent of Task) values, which represent the energy cost of an activity.
Running Pace
MET Value
Light jogging (5.0 mph)
6 METs
Running (6.0 mph)
8 METs
Running (7.0 mph)
10 METs
Running (8.0 mph)
11.5 METs
Running (9.0 mph)
12.8 METs

 

How to calculate:
  1. Find the MET for your pace.
  2. Know your body weight in kilograms.
  3. Convert your run time into hours.
  4. Use this formula:
  5. Calories Burned = MET x Body Weight (kg) x Duration (hours)
Example: If you weigh 65 kg and run at 8.0 mph for 45 minutes (0.75 hours):
Calories Burned = 11.5 x 65 x 0.75 = 563.6 kcal
Remember, this is an estimate – actual burn can vary based on individual factors.

Using Fitness Trackers and AppsA woman in workout clothes checks her smartwatch at the gym.
