Running While Pregnant: A Plan That Adapts to You

A free, flexible running plan to stay active during pregnancy, at your own pace and cleared by your OB-GYN

Running during pregnancy is safe for many women, as long as the intensity is right for you and your OB-GYN or midwife has cleared you for exercise. The American College of Obstetricians and Gynecologists (ACOG) supports staying active throughout an uncomplicated pregnancy — but every pregnancy is different, and the priority is always listening to your body and backing off the moment something feels off, trimester after trimester. This RunRun plan adjusts to how you're feeling at any point, with one goal: staying active without pushing your limits.

Why choose RunRun?

A plan that adjusts, anytime

Dial back the intensity or frequency of your runs in one tap, whenever your body or your OB-GYN says it's time. The plan bends to you — not the other way around.

Heart rate zones and pace

Find your comfortable effort and stay in a moderate heart rate zone with built-in tracking — a simple way to keep intensity in check.

A plan personalized by trimester

An auto-generated plan built to evolve alongside your pregnancy, trimester after trimester, with zero rigid routine.

Session tracking

A running log to track how you felt, your pace, and your consistency — a handy summary to bring to your next OB-GYN appointment.

Your baseline, saved for later

Your PRs and running history stay saved throughout pregnancy, so you can find your baseline again and ease back in postpartum, once your doctor clears you.

Sync your watch

Automatic sync with Strava, plus manual FIT/TCX export for Garmin devices.

A plan that grows with your pregnancy

Second trimester — Finding your rhythm

Many women feel a boost of energy at this stage. It's a good window to hold a steady, moderate volume — just stay hydrated and avoid running in the heat.

•25-minute easy run
•20-minute jog + 10-minute brisk walk
•30-minute run at a comfortable pace

Late pregnancy — Staying gently active

Walking becomes your main mode of movement. Your baseline stays saved in RunRun so you're ready for a gradual comeback after delivery.

•30-minute walk outdoors
•20-minute walk + gentle mobility work
•25-minute walk at a comfortable pace

Tips for running safely during pregnancy

Get cleared by your OB-GYN or midwife

Before you start or keep running during pregnancy, medical clearance is non-negotiable — it rules out any complication specific to your pregnancy. ACOG recommends checking in with your provider before starting or continuing any exercise routine.

Listen to your body, always

Unusual shortness of breath, pain, or dizziness override any goal in this plan. Slow down or stop running immediately if something feels wrong.

Stay hydrated and skip the heat

Drink water before, during, and after every run, and stick to cooler parts of the day — especially in summer.

Cut back the impact late in pregnancy

Favor soft surfaces, shorten your runs, and mix in more walking as your due date gets closer.

Adjust the plan anytime, no guilt involved

There's no such thing as underperforming here — backing off or skipping a run entirely is part of the process. RunRun's plan updates right along with you.

Can you run during pregnancy?

For most women with no complications, continuing to run during pregnancy is safe as long as the intensity is adjusted. ACOG supports staying active throughout an uncomplicated pregnancy — but it's still a call to make with your OB-GYN or midwife, who knows your full medical history.

Do I need to see a doctor before running while pregnant?

Yes, always. Whether you're already a runner or thinking about starting, you need medical clearance to confirm there's no reason physical activity would be unsafe for you.

How should my pace change trimester by trimester?

In general, intensity eases up gradually as your pregnancy progresses, with more walking mixed in later on. The exact pace is different for everyone — listen to your body and follow your OB-GYN's guidance.

Can you start running during pregnancy if you weren't a runner before?

That's a question for your OB-GYN or midwife, who can tell you whether it's a good fit for your situation. If you get the green light, start gently with brisk walking and short jogging intervals.

How do you get back to running after giving birth?

Your PRs and running history stay saved in RunRun, so you know your baseline before you start back up. The comeback itself needs sign-off from a healthcare provider, usually at your six-week postpartum checkup.

Stay active, on your own terms

RunRun builds an adjustable running plan for pregnancy, with pace and session tracking built in. No pressure to perform — just support that adapts to you and to your OB-GYN's guidance.
