Road runners are heading to the trails in bigger numbers than ever. You can see it in the race entries. You can see it in the shoe categories. You can see it at run clubs, where people who spent years running the same 10km road loop are now asking about fire trails and singletrack.
It makes sense. Trail running offers something most road running doesn't: variety, scenery, and a level of presence that's hard to replicate on pavement. When the terrain keeps changing, you can't zone out. You have to be in it.
If you're a road runner thinking about making the move, this guide covers what actually changes, how to approach it, and what to expect when you first get out there.
Why road runners go trail
The appeal is different for everyone, but a few things come up consistently.
The first is the mental switch. Road running can feel repetitive, especially if you're training for a specific goal race. Trails are genuinely interesting. Every kilometre looks different. You're picking lines, adjusting your stride, navigating roots and rocks. It keeps your head engaged in a way that roads don't always do.
The second is the physical demand. Trail running uses a completely different set of muscles to road running. The lateral stability work, the foot striking on uneven ground, the constant micro-adjustments to stay upright: all of it adds up to a workout that feels harder and more complete than an equivalent road session. Most runners find their first trail run surprisingly exhausting, even if they're fit on roads.
The third is the community. Trail runners are a genuinely welcoming group. The culture is collaborative, not competitive. People look out for each other on course. If you've been looking for a running community with a different feel, trails often deliver it.
The biggest adjustment: forget your pace
This is the thing road runners struggle with most. On the road, you're used to running at a target pace. You know what an easy kilometre feels like, what a tempo kilometre feels like, and where your race pace sits. On trails, that framework becomes almost useless.
A flat, well-groomed fire trail might feel close to road running. But single track with roots, a technical descent, or a long climb will slow you down dramatically regardless of your fitness. Your 5:30/km road pace might become 8:00 or 9:00/km on a moderate trail without any reduction in effort.
The fix is to run by effort, not pace. This is where understanding your effort zones becomes genuinely useful. Easy means you can talk comfortably. Moderate means breathing harder but controlled. Hard means short sentences only. Use those cues rather than GPS numbers and you'll find your footing quickly.
On climbs: walk. Even elite trail runners walk steep ascents. It's not a sign of weakness, it's smart race and training strategy. Power-hiking up a technical hill is often more efficient than running it, and it saves your legs for what comes next.
How to make the transition
The main mistake road runners make is going too hard, too technical, too soon. Your aerobic fitness might be excellent, but your ankle stability, proprioception, and trail-specific muscles are all starting from scratch. Give them time.
Start with easy, forgiving terrain. Fire trails and gravel paths are a good entry point. Avoid highly technical single track until you've got a few trail runs under your belt and a feel for how your body responds. Keep your first runs short, even if you're used to longer road sessions. An hour on trails is often enough.
Building strength work into your training helps significantly. Single-leg exercises, hip stability work, and calf raises all translate directly to trail performance. Runners who add a session or two of strength work per week adapt to trails noticeably faster.
If you're used to interval sessions on the road, you can replicate some of that on trails, but adjust the format to match the terrain. Hill repeats on a trail climb work well. Time-based intervals (run hard for 3 minutes, easy for 2) translate better than distance-based ones where pace is inconsistent.
Fueling and hydration
Trail runs typically take longer than road runs of the same distance. The effort is more variable, the terrain slows you down, and you may be far from water. Plan accordingly.
Pre-run fueling follows the same principles as road running, but err toward more rather than less. Trail running burns more energy per kilometre than road running, so your usual pre-run snack may not cut it for a longer session.
Carry water. Even on a short trail run, you'll often be further from help than you realise. A handheld bottle works fine for runs under 90 minutes. For longer efforts, a hydration vest gives you more capacity without the annoyance of holding something.
Gear: what actually matters
You don't need a lot to start trail running, but a few items genuinely make a difference. Building out your running kit sensibly means starting with the things that affect safety and comfort first.
Trail shoes. The most important piece of kit. Trail shoes have a lugged outsole designed for grip on dirt, mud, and rocks. Road shoes can work on fire trails, but they'll slip on anything wet or loose. If you're serious about trail running, trail shoes are worth the investment from the start.
Merino or trail socks. Thicker than road socks, with padding in high-friction zones. Worth it on longer runs where blisters from debris or moisture can become a real problem.
Sunglasses. Trails often move through changing light conditions, from dense canopy shade to exposed ridgelines in the same run. A photochromic lens that adapts to the light makes this much easier to manage. The Re. Adaptor lens is photochromic and goes near-clear in low light, which means it works under tree cover where a standard dark lens becomes a problem. For full conditions, the Infinity lens adds polarisation, anti-fog coating, and high-impact resistance alongside the photochromic technology. Not sure which lens fits your running? The lens guide covers it clearly.
Hydration carry. A handheld bottle or basic hydration vest. Start simple and upgrade if you move to longer efforts.
A technical top. Sweat-wicking fabric matters more on trails because you're often further from where you started and less able to just cut the run short if you get cold or wet. A lightweight, moisture-wicking layer covers a lot of scenarios.
What to expect on your first trail runs
You'll be slower than expected. That's normal. Trail running slows almost everyone down at first, and the adjustment takes a few weeks of regular runs.
Your legs will be more tired than they look like they should be. The lateral work on uneven ground is genuinely fatiguing, even when your heart rate stays low. Good recovery after trail runs matters more than it does after road sessions, especially early on.
You'll probably love it, or at least find it more interesting than expected. There's something about being on a trail, moving through actual landscape, that reconnects you with why you started running in the first place. It's not about splits. It's just about moving.
The community around trail running in Australia is strong, particularly in cities with access to national parks and bushland. Sydney, Melbourne, Brisbane, and Perth all have active trail running groups where newcomers are genuinely welcome. Getting out with a group is one of the fastest ways to learn good trail habits and find routes worth running.
Where to start
Pick a short loop on easy terrain, somewhere between 5 and 10km, on a surface that won't punish you if you stumble. Wear trail shoes if you have them, bring water, and plan to go easy. Check the weather beforehand, particularly for fire trail closures after rain or during high-risk periods.
Parkrun events happen on trail courses in some cities and are a good low-stakes way to try trail running with other people around. Many run clubs now have a monthly trail run alongside their usual road sessions.
Go slow, pay attention, and give it a few runs before you judge it. Most road runners who try trails end up running both, mixing the two depending on what they feel like that week. The trails are not a replacement. They're an addition.
If you're putting together your trail running kit, find the right sunglasses for how you run and build from there.

Founder, Re. (Re Your Run)
Tim built Re. after years of running in sunglasses that bounced, fogged, and ended up on his forehead. After discovering the UV damage that builds up without eye protection (even on cloudy days) and hearing the same frustrations from hundreds of other runners, he decided it was a problem worth fixing properly. With a background in Product across multiple industries, he approached it like any product problem: figure out what's broken, then build something that actually fixes it. He runs daily, co-founded Rose Bay Run Club, and Re. is his attempt to make one less thing that gets in the way of a good run.
