Yes, running with a stroller is measurably harder than running solo. Pushing a jogging stroller increases your oxygen cost by about 18%, raises your heart rate by 4 to 6 beats per minute, and typically slows your pace by 30 seconds to a minute per mile. The extra effort is real, but it’s also predictable, which means you can adjust your training around it.
How Much Harder Your Body Works
The most precise measurement comes from oxygen consumption, which reflects how hard your cardiovascular system is working at a given pace. Research published in the International Journal of Exercise Science found that the cost of transport (the oxygen your muscles need to cover a set distance) increases by 18.1% when pushing a stroller. That held true regardless of whether runners pushed with their arms straight out or angled downward.
In terms of calorie burn, the increase is more modest than you might expect. Pushing with two hands burns roughly 5% more calories than running the same pace without a stroller. One-handed pushing bumps that to about 6%, likely because your core has to work harder to stabilize your body asymmetrically. The gap between oxygen cost and calorie burn makes sense: your body is less efficient with the stroller, so you slow down, which partially offsets the extra energy demand per minute.
Heart rate tells a similar story. At a controlled pace of about 6 miles per hour, runners averaged 148 beats per minute without a stroller and 154 with one on an indoor track. Outdoors on a greenway, the difference was smaller, around 4 beats per minute. That’s noticeable on a heart rate monitor but not dramatic. If you train by heart rate zones, expect to sit a few beats higher at the same effort level.
What Changes in Your Running Form
One thing that doesn’t change much is your lower body mechanics. A study in the journal Gait & Posture found no significant differences in knee angles, ankle angles, stride length, cadence, or the time each foot spends on the ground when runners pushed a stroller at a steady pace. Your legs largely do the same job they always do.
The big shift happens in your upper body. The same study measured an average increase of 6.7 degrees in forward trunk lean. That’s substantial. Leaning forward that much changes where your weight sits relative to your hips, and over a long run, it adds up. Many stroller runners develop a posture where the pelvis drifts forward, the chest falls behind the hips, and the knees hyperextend slightly. This pattern is especially common in postpartum runners who may already carry residual posture changes from pregnancy.
From that position, pushing a stroller loads the spine and pelvic floor more than it needs to. Runners also tend to flare their elbows out to the sides, which pulls the shoulder blades forward and rounds the upper back. That puts extra strain on the neck and back because the shoulders aren’t positioned to absorb the stroller’s resistance effectively.
Why You Slow Down
Most stroller runners report losing 30 seconds to a full minute per mile compared to their usual easy pace, with hilly routes pushing that toward the higher end. The slowdown comes from several sources: the rolling resistance of the stroller wheels, the added weight (stroller plus child can easily reach 40 to 50 pounds), wind resistance from the stroller’s profile, and the simple fact that one or both arms are occupied and can’t swing naturally.
Arm swing matters more than most people realize. It counterbalances your leg movement and contributes to forward momentum. When you lock one or both hands onto a handlebar, you lose that rotational energy, and your legs have to compensate. This is part of why one-handed pushing actually costs slightly more energy than two-handed pushing: your trunk has to do extra stabilization work that your free arm can’t offset.
Injury Risks to Watch For
The increased forward lean and altered arm position create a chain of compensation that can show up as pain in several places. Back pain is the most common complaint, followed by calf tightness, knee discomfort, and pelvic floor strain. Runners who overstride while pushing (landing with the foot well ahead of the body) essentially brake with every step, sending extra force through the plantar fascia, Achilles tendon, and up through the knee.
Postpartum runners face an additional factor. Hormones that increase tissue flexibility during pregnancy remain active in the body until three to six months after breastfeeding stops. That means joints and ligaments may be more vulnerable to strain during the exact period when many parents start running with a stroller. This doesn’t mean you shouldn’t run. It means the combination of altered mechanics and increased tissue laxity deserves attention.
Spending too long on the ground with each step is another pattern that stroller running can encourage. When you slow your pace and lean forward, it’s easy to let each foot linger on the ground a beat longer. Most running injuries happen during ground contact, when gravity and body weight compress your joints. Keeping your steps quick and light, even at a slower pace, reduces those compressive forces.
How to Make It Easier
Keep your chest stacked over your hips rather than leaning into the stroller. Think about standing tall and letting your arms extend to the handlebar rather than hunching toward it. Your elbows should stay close to your sides, not flared out like wings.
Alternate hands if you push one-handed, switching every few minutes to distribute the asymmetric load. If you push with two hands, keep a light grip. You’re guiding the stroller, not death-gripping it. On flat ground, you can periodically let go entirely for a few strides to restore your natural arm swing.
Adjust your pace expectations. If your normal easy run is 9:00 per mile, plan for 9:30 to 10:00 with the stroller and don’t treat the slowdown as a fitness loss. It’s physics. If you train by heart rate, use that as your guide and let the pace fall where it falls. Smooth, paved surfaces also make a noticeable difference in rolling resistance compared to gravel or grass, especially with smaller-wheeled strollers.
Age Guidelines for Your Child
The American Academy of Pediatrics recommends waiting until your baby is at least six months old before running with a jogging stroller. The key milestone is trunk and neck control: your baby needs to hold their head steady and sit with support. Even after six months, stick to smooth surfaces until around 12 months, when your child’s core strength is better equipped to handle the jostling of uneven terrain.
