Running While Pregnant: What Every Expecting Mother Should Know (ACOG-Guided Advice)

Jason Keigher • November 21, 2025

Many expecting mothers wonder whether it’s safe to continue running during pregnancy. The short answer: Yes—running during pregnancy can be safe and highly beneficial when done with proper precautions, especially if you were already running or jogging before becoming pregnant.


At Bump Wellness, we support safe, effective prenatal fitness based on the recommendations from the American College of Obstetricians and Gynecologists (ACOG). Here’s what you need to know if you want to continue (or begin) running during pregnancy.


Is Running Safe During Pregnancy?

According to ACOG, pregnant women should get at least 150 minutes of moderate-intensity aerobic activity per week, and running can count toward that total. Running is considered safe for most pregnancies when:


✔ You were a runner before pregnancy

Women with an established running routine can continue with modifications as needed.


✔ Your pregnancy is uncomplicated

Your doctor has not advised against exercise.


✔ You listen to your body and adjust intensity

This becomes more important as pregnancy progresses.


If you were NOT a runner before pregnancy, ACOG recommends starting with walking or low-impact exercise first, and adding short, light jogging intervals only if approved by your healthcare provider.



Benefits of Running During Pregnancy

Running can offer several science-backed benefits for expectant mothers:


1. Supports Heart Health & Circulation

Running boosts cardiovascular conditioning, which can help with labor endurance and overall pregnancy stamina.


2. Helps Manage Healthy Weight Gain

Regular movement helps regulate weight gain within recommended ranges.


3. Improves Mood & Reduces Stress

Aerobic exercise releases endorphins, improves sleep, and lowers feelings of anxiety.


4. Supports Blood Sugar Control

Running improves insulin sensitivity and may help reduce the risk of gestational diabetes.


5. Strengthens Core, Hips, and Legs

Running engages major muscle groups that support posture and balance during pregnancy.



Important ACOG-Based Safety Guidelines

These guidelines reflect ACOG’s most recent exercise recommendations for pregnant women.


✔ Get medical clearance first

Especially if you have:

  • Heart or lung disease
  • Preeclampsia or high blood pressure
  • Cervical insufficiency
  • Placenta previa after 26 weeks
  • Risk of preterm labor
  • Multiple gestation with risk factors


✔ Use the “talk test” for intensity

During pregnancy, aim for moderate intensity:

  • You should be breathing more heavily but still able to speak in short sentences.

Avoid high-intensity running unless your OB has cleared it and you were already training at that level pre-pregnancy.


✔ Prioritize hydration

Pregnant women are more prone to dehydration. Drink water before, during, and after runs.


✔ Avoid overheating

ACOG specifically warns against excessive heat.
Choose:

  • Early morning or evening runs
  • Shaded areas
  • Indoor treadmill sessions on hot days


✔ Modify as pregnancy progresses

Running may feel different as your baby grows. It's normal to slow the pace or transition to run/walk intervals.


✔ Pay attention to balance changes

The belly shifts your center of gravity, which can increase fall risk. Stick to smooth, even surfaces.



Signs to Stop Running Immediately (ACOG Warning Signs)

ACOG states to stop exercise and call your doctor if you experience:

  • Vaginal bleeding
  • Dizziness or feeling faint
  • Chest pain
  • Regular painful contractions
  • Shortness of breath before starting exercise
  • Fluid leaking from the vagina
  • Calf pain or swelling
  • Headache
  • Decreased fetal movement

Never try to “push through” these symptoms.



When Running May Not Be Recommended

You may need to avoid running if you have:

  • Placenta previa after 26 weeks
  • Preeclampsia or gestational hypertension
  • Severe anemia
  • Preterm labor risk
  • Short cervix
  • A heart or lung condition
  • Doctor-ordered activity restrictions

Always follow your OB-GYN’s specific instructions.
