Urinary Series: Leaking with running

Leaking With Running or Exercise: Why It Happens and What You Can Do

Leaking urine during running, jumping, or higher-impact exercise is very common, but it is not something you just have to accept. Most often, it comes down to a combination of pelvic floor coordination, pressure management, and movement mechanics. The good news is that all of these are trainable.

First: understand what type of issue this might be

Not all leakage with activity comes from the same cause. Understanding why it is happening helps guide what to do next.

1. Excessive pelvic floor tension

This surprises many people, but a pelvic floor that is too tight can leak just as easily as one that is weak. Your muscles can only hold tension for so long before they fatigue. When they are constantly “on,” they eventually lose their ability to respond quickly and efficiently, especially during impact activities like running.

What this can look like:

• Larger volume leakage (feels like a “release” or sudden loss as if the dam breaks)

• Tightness in hips, pelvis, or pelvic floor

• Difficulty relaxing or “letting go”

What helps:

The goal here is not more tightening, it is reducing tension for better ability to lengthen and strengthen.

Focus on:

• Relaxation and down-training the pelvic floor

• Hip and pelvic opening mobility

• Breathing that allows the abdomen and pelvic floor to soften

• Internal work when appropriate (pelvic floor massage, dilators, or pelvic wands)

Sometimes the pelvic floor needs to learn how to lengthen and recover, not just contract.

2. Pelvic floor weakness or delayed response

For some people, leakage is related to small dribbles during impact, which can indicate reduced strength or timing.

This is where targeted strengthening can be helpful:

• Pelvic floor contractions (Kegels, when appropriate)

• Core and hip strengthening

• Coordination training with movement

The goal is not just strength; it is timing under load.

3. Bladder irritants

The bladder itself can be more reactive depending on what you consume.

Common irritants include:

• Caffeine

• Carbonation

• Alcohol

• Highly acidic foods or drinks

If symptoms seem inconsistent, consider tracking intake and reintroducing potential triggers one at a time to see what changes your symptoms.

Next step: look at how you move

Sometimes leakage is less about the pelvic floor itself and more about how pressure is managed through the body during movement.

Movement patterns that can contribute to leakage

·       Forward rounded posture: A rounded upper back and collapsed chest can reduce efficient core activation, which may increase downward pressure into the pelvic floor.

·       Heavy heel strike or jarring impact: A loud or heavy landing pattern can send more force upward through the pelvis.

·       “Sucking in” the stomach while running: This is a common compensation, but it often increases internal pressure rather than distributing it. Tight clothing that compresses the abdomen can have a similar effect.

What to aim for instead

A more efficient running posture often looks like:

• Upright but relaxed chest

• Shoulders down and loose (not braced)

• Slight forward lean from the ankles

• Soft, quiet, smooth steps

• Rhythm rather than rigidity

The goal is not perfection—it is efficiency and reduced strain through the pelvic floor.

Training strategies

Once you understand the contributing factors, you can start rebuilding tolerance.

1. Start where your body is successful

Begin at a level where you can:

• Run or move without leakage

• Maintain good form without strain

• Recover well after activity

This becomes your baseline. Progress comes after control is consistent not before.

2. Use incline or posture cues

If running on a treadmill:

• A slight incline (1–2%) can help naturally improve posture

• It can also encourage glute engagement and reduce collapse through the pelvis

3. Impact training (graded exposure)

If your body leaks with impact, it can be helpful to gradually retrain tolerance through controlled exposure:

Examples:

• Marching or jogging in place

• Wall-supported running drills

• Mountain climbers

• Gentle jumping progressions

These help the body learn that impact does not automatically equal leakage.

4. Bladder training basics

One of the most important pieces is bladder behavior. Try to reduce “just in case” peeing When you frequently empty your bladder without urgency, your system adapts to smaller and smaller volumes. Over time, this can increase urgency and reduce tolerance.

Instead, aim to:

• Respond to true urge signals

• Allow more normal bladder filling patterns

• Build tolerance gradually over time

When to get help

You should consider pelvic floor physical therapy if:

• You leak consistently with running or exercise

• You avoid activity due to fear of leakage

• You are unsure whether you need strengthening or relaxation

• Symptoms are not improving with basic changes

Most exercise-related leakage improves significantly with the right combination of strategy and training.

The bottom line

Leaking with exercise is not just a strength issue; it is usually a coordination and pressure management issue.

When you address muscle balance (too tight vs too weak), movement mechanics, bladder habits, and introduce a gradual training progression the body often responds well.

You do not have to stop running. You just need a system that supports your pelvic floor while you do it.
