Running vs Walking for Women in Perimenopause
Last updated
Running and walking are both cardiovascular exercises, but they stress the perimenopausal body very differently. Running delivers a higher cardiovascular stimulus but also higher joint impact, greater cortisol elevation, and increased pelvic floor stress — all of which matter more after 40 than before. Walking is gentler but requires more time to achieve cardiovascular benefits. The right choice depends on your current joint health, pelvic floor status, stress levels, and training history.
Running vs Walking: side by side
| Dimension | Running | Walking |
|---|---|---|
| Cardiovascular fitness | Superior VO2max improvement per minute of training | Effective for cardiovascular health, but requires more time |
| Joint impact | High — 2.5-3x body weight per stride; increases with speed | Low — 1-1.2x body weight per stride |
| Cortisol response | Significant — especially for runs longer than 45 minutes | Minimal — walking at conversational pace does not spike cortisol |
| Pelvic floor stress | High — impact forces stress a weakened pelvic floor | Low — minimal pelvic floor demand |
| Bone density | Moderate — impact provides some bone stimulus in the legs | Low — insufficient forces for bone building |
| Calorie burn | Higher per minute (8-12 cal/min) | Lower per minute (3-5 cal/min) |
| Muscle preservation | Chronic running can accelerate muscle loss | Neutral — walking neither builds nor destroys muscle |
| Accessibility | Requires baseline fitness, proper footwear, and healthy joints | Accessible to virtually everyone, anywhere |
When to choose Running
- You have a running history and your joints tolerate it well.
- Your pelvic floor is strong and asymptomatic.
- Your perimenopause symptoms are mild and cortisol is not a concern.
- You enjoy running and it supports your mental health.
When to choose Walking
- You have joint pain, especially in knees or hips.
- You experience any pelvic floor symptoms (leakage, heaviness).
- Stress and cortisol management are priorities.
- You are new to exercise or returning after a long break.
The short answer
Running or Walking? For most women in perimenopause, walking is the safer and more sustainable cardiovascular practice. Running is not forbidden if your body tolerates it, but the combination of joint stress, cortisol elevation, and pelvic floor impact makes it a higher-risk modality during hormonal transition. Neither walking nor running builds muscle or meaningful bone density — both should be supplemented with strength training 2-3x per week.
Frequently asked questions
Yes, if your joints and pelvic floor tolerate it. Reduce volume (fewer miles, not faster miles), add more rest days, and supplement with strength training. Listen to your body — if joint pain or pelvic floor symptoms appear, switch to walking.
Running does not cause pelvic floor dysfunction, but the impact forces can worsen existing weakness. If you experience leakage during running, see a pelvic floor physiotherapist before continuing.
A brisk pace (3.5-4.0 mph, or a pace where you can talk but not sing) provides the cardiovascular benefits. Strolling is still beneficial for mental health, but a brisk pace is needed for meaningful cardio fitness improvement.
Key takeaways
- Running and Walking serve different needs — there is no universal winner.
- The best choice depends on your specific goals, symptoms, and preferences.
- For women 40+ in perimenopause, strength training should be the foundation regardless of modality or app.
