Why running matters for your mental health

 Running doesn’t just change your body. It changes how you feel, how you think, and how you carry yourself, says TCS Sydney Marathon Head Coach Georgia Weir.

As a coach, I see it all the time. People start running because they want to change something about themselves – whether they realise it or not. It’s not always about fitness. Often, they’re feeling mentally flat, disconnected, or unsure of themselves.

And then something starts to shift. Not overnight, but through consistently showing up.

Mindset: The importance of starting

Marathon training, in particular, goes beyond the physical. It challenges you to stay in it when it’s uncomfortable, to keep showing up when motivation drops, and to work through doubt. The resilience built through that process carries into other areas of life.

Mindset is what allows you to stay in it when it gets hard. That’s why this side of training matters. Programs like Marathon State of Mind created by Olympian Eloise Wellings and mental performance coach Dr Rory Darkins, focus on building the mental skills that help runners develop resilience, confidence, and the ability to stay present when things get tough.

We now have the data to support what we see every day – regular movement improves mood, reduces anxiety, and supports overall mental wellbeing. You don’t need to have everything figured out. You just need to start – because movement changes things.

Safety & Wellbeing: Training as a woman

However, I’ve learned quickly that training isn’t one-size-fits-all, especially for women. There are additional layers to consider. Not as barriers, but as things to understand so you can train in a way that actually works for you.

The first is your cycle – energy, strength, and recovery can shift across the month. There are times you’ll feel strong and ready to push, and others where everything feels heavier. That’s normal. The key is not to fight it, but to work with it. Adjusting your training isn’t a lack of discipline, it’s awareness. And that leads to consistency.

Beyond the physical, there’s also safety. Where you run, when you run, and who you run with matters. Choosing well-lit routes, letting someone know where you are, running with others, and trusting your instincts all make a difference. Feeling safe allows you to relax into your running and that’s where progress happens.

There’s also the reality of balancing training with work, family, and life. Training needs to fit in, not compete. From my experience, the women who progress most aren’t the ones doing everything perfectly. They’re the ones who stay consistent, adapt, and keep showing up. That’s what builds something sustainable.

Community: Reaching out for support

One of the biggest things I’ve seen through running isn’t just physical change, it’s what happens when people start to let their guard down.

People show up carrying a lot. Stress, pressure, responsibility. At first, they hold it tightly. But over time, something shifts. Running has a way of breaking that down. I’ve been lucky to witness this hundreds of times.

I remember one runner who struggled to leave her house. A few months later, she was up before sunrise, showing up to run not because she had to, but because she felt part of something. That’s the power of community. It’s showing up, sharing the effort, the laughs, the tough sessions. You don’t have to explain everything. You just have to be there.

Making an impact with your running

This same idea carries into Impact Week and the TCS Sydney Marathon[LC1] . Running for a charity gives your training purpose. It connects your effort to something bigger and creates real impact for people who need support, opportunity or access they wouldn’t otherwise have.

When people donate, they’re not just giving money. They’re backing something real. And together, that creates impact well beyond the finish line. When you combine running with purpose, it creates impact beyond yourself.
