Biking vs Running for Your Fitness Goals

If you’re looking to add more cardio into your routine, there’s a good chance you’ve considered either biking or running. Both are classic, accessible workouts that get your heart pumping and can be done almost anywhere. But when it comes to choosing between the two, the best option depends on your personal fitness goals, body needs, and lifestyle preferences.

Let’s break down the key differences to help you decide which one is right for you.

Calorie Burn: Running Has the Edge

In general, running burns more calories than biking especially at higher speeds. Here’s a rough breakdown for a 155-pound person:

• Running at 5 mph: 298 calories in 30 minutes

• Cycling at 12–13.9 mph: 298 calories in 30 minutes

• Running at 7.5 mph: 465 calories

• Cycling at 16–19 mph: 446 calories

Because running requires your body to support its full weight, it tends to be more intense per minute. But that doesn’t mean it’s always the better choice especially if it causes discomfort or strain.

Weight Loss: It’s About Sustainability

While running may burn more calories per minute, biking can be easier to sustain for longer periods of time, particularly if you enjoy it more. A long, steady ride might burn more calories overall than a short run, simply because you’re likely to go farther and stay active longer.

The key to weight loss isn’t just intensity it’s consistency. Choose the option you’ll stick with and enjoy. A 2013 study also found that both running and biking may help suppress appetite in the short term, potentially supporting weight management goals.

Joint Impact: Cycling Is Gentler

One of the biggest differences between biking and running is impact. Running is a high-impact exercise, which means it places stress on your knees, ankles, and hips. That’s great for bone strength but it also increases the risk of injury, especially if you have existing joint issues.

Cycling, on the other hand, is low-impact and ideal for those looking to avoid excess joint strain. It’s often recommended for people recovering from injuries or managing chronic pain, although it can cause lower back discomfort if posture or fit is off.

Heart Health: Both Come Out on Top

Both biking and running are excellent for cardiovascular health. Regular aerobic activity strengthens the heart, improves circulation, and helps lower blood pressure and cholesterol.

However, a 2014 review noted that too much intense endurance training—over five hours a week could potentially stress the heart over time. So, no matter your preferred activity, moderation is key.

Muscle Tone: Different Gains

Running helps maintain lean muscle, especially in your legs and core, but it doesn’t build much muscle on its own. Biking, while also a cardio activity, provides some resistance training through pedaling especially uphill or at higher gears. This can help tone and strengthen your quads, glutes, and calves.

For optimal muscle definition, combining either activity with strength training is your best bet.

Other Factors to Consider

• Cost: Running is virtually free once you have a decent pair of shoes. Cycling can involve a higher upfront investment, including the bike, gear, and maintenance.

• Convenience: Running can happen anywhere even on a treadmill. Cycling requires access to a bike, road space, or indoor equipment.

• Safety: Running generally has fewer risks than outdoor cycling, which involves traffic, terrain, and weather conditions.

• Chronic Conditions: Always check with your doctor, especially if you have underlying health issues like diabetes or arthritis. Cycling may be safer for joints, while running might offer better glucose regulation in some cases.

The Bottom Line: Choose What You’ll Stick With

Neither biking nor running is universally better they both have their advantages. Running burns more calories and can be great for quick, effective workouts. Cycling is easier on the joints, potentially more enjoyable for longer sessions, and still delivers powerful cardiovascular benefits.

Ultimately, the best choice is the one that keeps you moving consistently. If it energizes you, feels good on your body, and fits your lifestyle, you’re on the right track literally or figuratively.
