A 5-mile bike ride burns roughly 200 to 300 calories for most people. The exact number depends on how fast you ride, how much you weigh, and the terrain. A 155-pound rider cruising at a casual 10 mph will burn about 240 calories over those 5 miles, while a 180-pound rider at the same pace burns closer to 280.
Calories Burned by Speed and Weight
Calorie burn during cycling comes down to a simple formula: your metabolic effort level (measured in METs), your body weight in kilograms, and how long you’re on the bike. The Compendium of Physical Activities assigns specific MET values to different cycling speeds:
- Under 10 mph (casual cruising): 4.0 METs
- 10 to 12 mph (leisurely pace): 6.8 METs
- 12 to 14 mph (moderate effort): 8.0 METs
- 14 to 16 mph (fast, vigorous): 10.0 METs
One MET equals roughly 1 calorie burned per kilogram of body weight per hour. So if you weigh 155 pounds (70 kg) and ride at 10 mph, you’d burn about 6.8 × 70 × 0.5 hours = 238 calories over your 30-minute, 5-mile ride.
Here’s how the numbers break down for a 5-mile ride at different speeds and body weights:
At 10 mph (30 minutes to complete 5 miles):
- 130 lbs: ~200 calories
- 155 lbs: ~238 calories
- 180 lbs: ~277 calories
At 13 mph (about 23 minutes):
- 130 lbs: ~182 calories
- 155 lbs: ~215 calories
- 180 lbs: ~251 calories
At 15 mph (20 minutes):
- 130 lbs: ~196 calories
- 155 lbs: ~234 calories
- 180 lbs: ~272 calories
Why Faster Doesn’t Always Mean More Calories
You’ll notice something counterintuitive in those numbers: riding faster doesn’t necessarily burn more total calories over 5 miles. That’s because speed increases your effort per minute but decreases the time you spend riding. At 10 mph, you’re pedaling for 30 minutes. At 15 mph, you’re done in 20. The higher intensity per minute roughly offsets the shorter duration, so the totals land in a similar range.
The real calorie difference shows up when you compare effort over the same time period, not the same distance. If you rode for 30 minutes at 15 mph instead of 10 mph, you’d cover 7.5 miles and burn significantly more. For a fixed 5-mile route, though, your body weight matters more than your speed when it comes to total calories burned.
Terrain, Wind, and Real-World Conditions
The MET-based estimates above assume flat ground with little wind. In practice, both hills and headwinds can push your calorie burn well above these numbers.
Wind resistance is the dominant force working against a cyclist on flat terrain. Research from wind tunnel testing found that the aerodynamic drag on a cyclist increases with the square of wind speed, meaning a 20 mph headwind creates four times the resistance of a 10 mph headwind. Even a moderate breeze blowing against you can increase your effort significantly without changing your speed at all. Riding into a stiff headwind at 12 mph can feel like riding at 16 mph on a calm day.
Hills have a similar effect. Climbing adds the work of lifting your body weight against gravity, which MET values for flat riding don’t account for. A hilly 5-mile route can easily burn 30 to 50 percent more calories than the same distance on flat ground. Conversely, a tailwind or a net downhill route will reduce your calorie burn below these estimates.
Bike Type Makes a Difference
The type of bike you ride changes how much energy you spend over 5 miles. A heavy cruiser or mountain bike with knobby tires creates more rolling resistance than a lightweight road bike with thin, smooth tires. Riding a mountain bike on pavement at the same speed as a road bike requires noticeably more effort, which translates to more calories burned per mile.
Riding position also plays a role. An upright riding position on a cruiser or hybrid bike catches more wind than the tucked position on a road bike. That increased frontal area means more drag, more work, and more calories. If you’re riding an e-bike with pedal assist, expect to burn roughly 25 to 50 percent fewer calories than a standard bike at the same speed, since the motor is sharing the workload.
How to Estimate Your Own Burn
For a quick personal estimate, use this formula: multiply the MET value for your speed by your weight in kilograms, then multiply by the time in hours. To convert your weight, divide pounds by 2.2. To find your time, divide 5 by your average speed in mph, which gives you hours.
So for a 170-pound rider (77 kg) averaging 12 mph: that’s a MET of 8.0, a ride time of about 0.42 hours (25 minutes), and the calculation is 8.0 × 77 × 0.42 = 259 calories.
Keep in mind that these are estimates of total calories, including what your body would burn at rest during that same time period. Your “extra” calories burned from the exercise itself are roughly 10 to 15 percent lower. For most people tracking their rides for fitness or weight management, though, the total MET-based estimate is the standard number to use and the one that matches what most fitness apps report.
