Welcome back to CLIMB. Over the last two winter articles, we’ve looked at how to stay consistent through winter and how to manage cold-weather riding in Canberra.Today, we’re continuing that winter training theme by looking at one of the biggest decisions cyclists and triathletes face at this time of year: should you train indoors, or brave the cold and get outside?
The answer is not always simple. It should not come down to guilt, toughness or what everyone else is doing. The better question is: what is the purpose of today’s session?
The Winter Dilemma: Do I Brave the Cold or Stay Inside?
Let’s be honest. Winter in Canberra can test even the most committed athlete.
I know, because I’m right there with you. Some days, I’m out on the trails at Bruce Ridge or sneaking in a lunchtime ride or run when work allows. Other days, I’m riding with mates under lights on a crisp night MTB session. Don’t knock it until you try it, by the way. It is a great way to explore your favourite trails differently.
But then there are mornings where the alarm goes off, the frost is sitting on the lawn, and even with years of experience, my brain says: nope, not today. That is exactly when the indoor trainer becomes a very useful training partner.
We’ve already talked about how the right winter layers can make outdoor riding more manageable, and how small routine changes can help you stay fit through winter. But even with all of that, there are days when it is simply better — and smarter — to stay inside.
The good news is that both options have value. Indoor and outdoor training are not competing against each other. They serve different purposes. The key is knowing which one is right for the session you are trying to complete.
Indoor Training – Precision & Control
Indoor training offers something outdoor training rarely does: Control.
There’s no traffic, no sudden weather changes, no kangaroos jumping across the path (yes, it’s happened!). You can execute precise intervals with consistent power, heart rate, speed and cadence.This makes indoor training especially useful for structured sessions where the purpose is clear and the effort needs to be controlled.
Multiple studies, including those by Chavarrias et al. (2019), have shown that indoor training can match or even exceed outdoor sessions in terms of physiological adaptations, primarily because it allows you to reach and hold your training zones without external disruptions.
Structured indoor sessions are ideal for higher-quality work, including sweet spot, threshold and VO2 max sessions. They can help you maintain consistency, build fitness and protect the rhythm of your week when winter conditions make outdoor training harder.
But while indoor training is efficient, it is not perfect. It lacks the real-world skills of handling, balance, and terrain variation. And psychologically, it can sometimes feel monotonous — the phenomenon of “Zwift fatigue“ is a real occurrence.
So indoor training is a powerful tool, but it should not be the only tool.
Outdoor Training – Skill & Mental Resilience
Outdoor training, on the other hand, challenges more than just your physiology. You’re constantly engaging your neuromuscular system: steering, reacting, cornering, descending, and foot placement. These real-world demands help develop essential technical proficiency, especially when preparing for races or events (Bicycling, 2022).
There’s also the emotional side. Exposure to natural light helps regulate mood and sleep (Czeisler & Gooley, 2007), supports vitamin D levels for immune health, and contributes to our overall sense of well-being. Those winter lunchtime rides? They do wonders for clearing the mind and breaking up long workdays.
But outdoor riding isn’t always practical or safe. Canberra’s icy mornings, rain, wind, short daylight, or black ice can make it risky, especially if you’re fatigued, rushed or not fully focused.
This is where the decision becomes less about toughness and more about purpose..
It’s Not Either/Or — It’s About Blending Intelligently
This is where I step in as a coach to guide you through these choices and help you make decisions that feel right for you. Many have heard me say this before: performance isn’t about doing everything perfectly. It’s about making intentional, informed decisions that align with your goals, life, and energy.
Sometimes, you might schedule more indoor sessions because life is busy, the mornings are icy, or you do not want to fight the elements. Other weeks, you might take the opportunity to get outside for a skills ride, a run along the lake, or a night MTB adventure with friends.
And let’s not forget swimming — another winter challenge for many triathletes. While the heated pool offers consistency, winter can still test motivation to get there. Indoor swim sessions are ideal for technique work, controlled pacing, and strength development, as they eliminate the challenges of battling open water elements. And when possible, open water swims — even occasional ones — keep sighting and water confidence sharp. Again, it’s about blending what works for your season and goals.
Again, it is about blending what works for your season, your goals and your current life context.
Consistency matters more than the platform.
As long as you are training with purpose, you are progressing..
Avoiding the Overload Trap
One thing I’ve noticed more than ever: there’s an overwhelming amount of advice out there. Zwift plans, YouTube experts, podcasts, and social media influencers all shout: “This is the best way to train!”
This is where many people get stuck. Not because they are lazy. Not because they are uncommitted. But because they are trying to make decisions with too much noise and not enough clarity.
My role as a coach is to cut through that noise. I help you understand what works best for you — your physiology, your schedule, your mindset, your goals and your real life. When you are balancing training with work, family and a Canberra winter, clarity matters more than perfection.
If you are second-guessing your plan or drowning in information, coaching brings simplicity, structure and accountability. And most importantly, it helps keep the fun and purpose alive — even when it is minus two outside.
A Winter Mindset to Thrive
So as you navigate the next few months, remember:
- Use indoor sessions for efficient, high-quality work.
- Use outdoor sessions for skill development, enjoyment, and mental rejuvenation.
- Give yourself permission to adapt based on the weather, your mood, and your goals.
- And never underestimate the power of having a coach in your corner to guide you.
You’ve got this.
Thank you for being part of the CLIMB community. I’m here to support your journey and would love to hear how you’re managing your training this winter.
If you’re finding it hard to stay consistent, personalised coaching can help you make clearer training decisions and keep moving through winter with purpose.
