Pelvic floor and running: the complete guide

Up to 40% of women experience urinary leaking during running. It's common. It's also not something you have to accept.

What is the pelvic floor? A hammock of muscles supporting the bladder, uterus, and bowel. It works with your deep core and diaphragm to manage intra-abdominal pressure — which spikes every time your foot hits the ground.

Why running causes leaking: Each footstrike creates a ground reaction force 2–3 times your body weight. The pelvic floor has to absorb this. If it's too weak, too tight, or poorly coordinated, it can't manage the pressure.

Note: Leaking can happen with both weak AND tight pelvic floors. Excessive tightening is sometimes the issue, not weakness.

Signs your pelvic floor may need attention:

• Leaking when you run, jump, or cough
• Urgency to urinate that's hard to control
• Heaviness or pressure in the pelvic region
• Lower back or hip pain that doesn't respond to other treatment

What helps:

1. Pelvic floor exercises — both slow holds and quick flicks (see Exercise Library)
2. Breathing mechanics — exhaling on exertion prevents pressure spikes
3. Posture — forward lean and hip drop both increase pelvic floor load
4. Stride adjustments — shorter, quicker steps (higher cadence) reduce impact force
5. Build slowly — start with shorter runs on softer surfaces

The most important step: See a women's health physiotherapist. A 2–3 session specialist assessment can identify whether the issue is weakness, tightness, or coordination — and give you a precise programme. This is athletic performance work, not medical management.
