Running Through

Perimenopause.

The years in which you become a more experienced and self-aware runner may also be the years in which your body begins responding differently.

For some women, perimenopause changes very little. For others, disrupted sleep, hot flushes, heavier or irregular bleeding, changing energy, joint symptoms, mood changes and slower recovery can make familiar training feel unfamiliar.

These experiences are real, but they are not identical for every woman and they should not be used to predict inevitable decline. The most useful approach is to notice what is changing for you, rule out other causes and adjust your training support accordingly.

What perimenopause means

Perimenopause is the transition leading up to menopause. During this time, ovarian hormone patterns become more variable and menstrual cycles may change. The timing, duration and symptoms differ considerably between women.

Menopause is reached after 12 consecutive months without a menstrual period when there is no other medical explanation. The years after that point are described as postmenopause.

Oestrogen and progesterone influence more than reproduction. They interact with systems involved in temperature regulation, sleep, bone turnover, mood and muscle function. This helps explain why hormonal change can affect how some women experience training.

It is also important not to attribute every change to menopause. Fatigue, breathlessness, poor recovery and changes in performance can have other causes, including low iron, under-fuelling, thyroid conditions, illness, stress and inadequate sleep.

What you may notice

There is no single perimenopausal running experience. Some athletes continue training without major disruption. Others notice patterns that affect their consistency, comfort or recovery.

You do not need to experience every symptom for the transition to be relevant. Nor should every difficult session be blamed on hormones. Track patterns across your cycle, symptoms, sleep, life load and training response. That information is far more useful than relying on one isolated day.

Keep running. Add strength.

Perimenopause is not a reason to remove long runs, hills, intervals or meaningful trail goals. Aerobic exercise continues to support cardiovascular health, mental wellbeing, fitness and function through midlife and beyond.

Strength training becomes increasingly valuable because it supports muscle, bone, balance, running economy and the body’s ability to tolerate load. Australian guidelines recommend muscle-strengthening activity on at least two days each week.

Use exercises that train the major movement patterns needed on the trail: squatting, hinging, stepping, pushing, pulling, carrying and single-leg control. The resistance should be challenging enough to create adaptation, but the load and technique need to progress safely from your current level.

Protect muscle and bone

Bone loss accelerates around menopause as oestrogen declines. Running is a weight-bearing activity and can contribute to bone health, but the strongest approach combines weight-bearing movement with progressive resistance training, balance work and, where appropriate, varied impact.

Impact training does not need to mean large volumes of jumping. Depending on your history and current capacity, it may include jogging, hill work, stair climbing, skipping, small jumps or multidirectional movement. Women with osteoporosis, previous fractures, pelvic-floor symptoms or other clinical concerns should seek individual guidance before introducing higher-impact work.

Muscle also needs a reason to remain strong. Consistent resistance training and adequate protein are more useful than trying to protect muscle through supplements alone.

Fuel the athlete you are now

A common response to body-composition change is to eat less while continuing to train hard. This can work against the goals of protecting muscle, bone, recovery and performance.

Your body still needs enough overall energy and carbohydrate to support running. It also benefits from protein distributed across the day rather than relying on one large serving at dinner.

Sports-nutrition guidance commonly places active women within a broad range of approximately 1.4 to 2.0 grams of protein per kilogram of body weight each day. This is not a universal prescription. Your needs depend on your training, body size, health, dietary preferences and overall energy intake.

Heat, sleep and recovery

Hot flushes, night sweats and changing temperature regulation can make heat feel less manageable. The effect varies between women, so use your own experience rather than assuming your hydration or pace must follow a universal menopause formula.

In warm conditions, you may benefit from starting earlier, choosing shaded routes, wearing breathable clothing, carrying enough fluid and adjusting pace to effort. Electrolyte needs depend on conditions, duration and individual sweat losses. Menopause alone does not determine a specific sodium requirement.

Sleep disruption can also reduce your capacity for the next day’s training. One poor night does not automatically require cancelling a session, but it is sensible to consider the full picture.

Trail Note  ·  07

Adjust the program without abandoning it

Training through perimenopause is not automatically about doing less. It is about matching the program to your current recovery, symptoms and goals.

Trail Note  ·  08

Joint and tendon symptoms

Some women report more joint or muscle discomfort during perimenopause. Researchers are still working to understand the relationship between hormonal change, ageing, pain and tendon health. It is too simple to assume that every Achilles, knee or plantar-fascia problem is caused by declining oestrogen.

Training history, sudden changes in load, strength, sleep, recovery, previous injury and overall health remain important. The practical response is familiar: progress load gradually, warm up sufficiently, build calf and lower-limb strength and respond early when pain begins changing how you move.

If pain persists, worsens or alters your gait, seek an assessment rather than relying on generic rehabilitation exercises. Different injuries need different loading plans.

Trail Note  ·  09

The identity question

There can be grief in noticing that pace, recovery or body composition no longer responds in quite the same way. Running holds identity as well as fitness, so these changes can land more deeply than a number on a watch.

But changing your approach does not mean lowering your ambition. It can mean becoming clearer about what progress looks like now: effort over automatic comparison, quality over unnecessary volume, strength alongside endurance and consistency that can be sustained.

When to seek medical support

Speak with a GP if symptoms are affecting your quality of life, sleep, mental health or ability to train. Heavy bleeding, bleeding after menopause, persistent pain, marked breathlessness or significant unexplained fatigue should also be assessed rather than assumed to be part of the transition.

Menopausal hormone therapy is the most effective treatment for hot flushes and night sweats and can be safe and appropriate for many symptomatic women. It is not suitable for everyone, and the potential benefits, risks, type and timing need to be discussed individually with a qualified clinician.

Hormone therapy should be considered for symptom management and health needs, not promoted as a guaranteed performance intervention. Hormonal and non-hormonal treatment options are available.
