5 Trail Running Tips for Fall… Before the Window Closes
It’s October and honestly… this might be my favorite time of year to be on the trails.
The air is crisp, the colors are unreal, and there’s something about fall trail running that just hits differently than any other season. But it also comes with its own set of things to pay attention to, and if you’re newer to trails or you’re coming back after a summer of road running, I want to make sure you’re set up to actually enjoy it out there.
Because here’s the thing about October trails… the window is real. The days are getting shorter, the temperatures are dropping, and depending on where you are, trail conditions can change fast. So let’s make the most of what’s left.
Below are my top tips for adapting to fall terrain, dressing right for the temperature swings, staying fueled and hydrated when you don’t feel like it, keeping yourself safe as the daylight shrinks, and being a good human out there on the trail. Whether this is your first time off pavement or you’ve been doing this for years, hopefully there’s something useful here for you.
1. Adapting to Fall Terrain
Here’s the first thing you need to know about October trails… the leaves look beautiful and they will absolutely try to take you out.
Fallen leaves on the trail hide everything. Roots, rocks, divots, drop-offs. What looks like a clear path can have a root right underneath that you won’t see until your foot catches it. And wet leaves on a descent? Genuinely slippery in a way that catches people off guard even when they know it’s coming.
Your road pace and road ability do not automatically transfer to trails in any season, but fall adds an extra layer of unpredictability. Shorten your stride, slow your pace on descents especially, and keep your eyes further ahead on the trail than you think you need to. You want to be reading the ground a few steps in front of you, not right at your feet.
Before you head out, research your trail. Check conditions using something like Strava or AllTrails and pay attention to recent reports from other runners. A day of rain plus fallen leaves is a completely different trail than a dry October morning. Know what you’re getting into before you’re in it.
2. Dressing for October Temperature Swings
Let’s start with shoes because this matters more than people think. Trail shoes are built differently than road shoes… a more fitted toe box, better grip, and a stiffer sole to help you handle uneven ground. In October especially, that grip matters on wet leaves and slick roots. If you’ve been running trails in road shoes, this is the season where you’ll really feel the difference.
As for clothing, layers are everything in the fall. You might start a run in 45 degrees and feel like it’s 60 by mile two. You might start at 55 and have the temperature drop the second the sun goes behind clouds or you gain some elevation. The range in a single run can be significant.
My general rule is to dress like it’s about 10 to 15 degrees warmer than the actual temperature because you’ll heat up fast once you get moving. Look for breathable moisture-wicking fabrics and always… always… have a windproof layer with you. Not in your car. With you. Something lightweight that folds down small enough to stuff in a vest pocket or pack.
I’d genuinely recommend running with a vest or pack this time of year so you have somewhere to carry that layer, an emergency poncho, and a waterproof pouch for your phone, keys, and wallet. It might feel like a lot for a shorter run but the conditions can shift faster than you’d expect in October and you’ll be really glad you had it.
3. Hydration and Fueling When You Don’t Feel Like It
Here’s the thing about fall running that catches people off guard… you don’t feel as thirsty.
The air is cooler, you’re not dripping sweat the way you were in July, and the thirst cues that remind you to drink in summer just aren’t as loud. But your body is still working just as hard on these trails and the dry fall air actually increases your fluid losses even when you can’t feel it happening.
Drink on a schedule, not just when you feel thirsty. Bring more than you think you need. Most trails don’t have water stops so you’re carrying everything with you and a hydration vest or pack makes this so much easier.
Eat something real before you head out too. Fall trails come with extra unknowns… it gets dark earlier, conditions change, you might take longer than expected on technical terrain. I always carry more fuel than I think I’ll need. And one of my favorite small tricks… leave a sports drink or extra water and electrolytes in your car for when you finish. It takes the pressure off carrying everything with you and honestly it’s a really nice thing to come back to at the end of a cold run.
4. Safety When the Daylight Is Shrinking
This one I want you to take seriously in October because it sneaks up on people.
Sunset is around 6pm right now and getting earlier every day. The tree cover on trails makes it get dark significantly faster than it does out in the open. A run that starts in full daylight can end in low light or actual dark before you realize it’s happening, especially if you went a little further than planned or your pace was slower than expected on technical terrain.
Carry a headlamp or a flashlight. Every single time. Even if you’re planning a short run and you think you’ll be back well before dark. Conditions change and plans change and being on a trail in the dark without a light is genuinely not a situation you want to be in.
Tell someone where you’re going, your route, and when to expect you back. This is always good practice on trails but it matters more in the fall when the margin for error is smaller.
A lot of running watches and apps now have safety features that can share your location or send an SOS if something goes wrong, and those are worth knowing about and having set up before you need them. Keep your phone’s emergency contacts easy to access too.
One more fall-specific thing worth knowing… hunting season runs through the fall in a lot of areas. Bright colors are your friend out there. A blaze orange layer or at least something visible is a smart call on trails that allow hunting, and it’s worth checking whether the trail you’re planning runs through any hunting land before you go.
What I’d pack for a fall trail run:
- Trail running shoes
- Breathable moisture-wicking layers
- Windproof jacket (on your body or in your pack… not in your car)
- Vest or hydration pack
- Headlamp or flashlight
- Waterproof pouch for phone, keys, and ID or wallet
- Electrolytes and fuel
- Emergency poncho
- First aid kit
- Navigation tools
- Bright or visible color layer
- Medical ID if relevant
Trail running asks a little more of your attention than road running does. Between watching for hidden roots under leaves, tracking the light, and staying aware of your surroundings, I’d genuinely recommend skipping the headphones out here. Or at least keeping one ear free.
5. Trail Etiquette
We’re guests on these trails so let’s treat them that way. Pack out everything you bring in, stay on the main trail, and if you brought something in a ziplock bag, that bag becomes your trash bag on the way out.
A few other etiquette basics… keep the noise down and skip the portable speaker so you can stay aware of your surroundings and be considerate of everyone else out there. When you’re passing someone, a friendly “on your left” goes a long way. Yield to uphill traffic when you can.
And if a trail allows cyclists or horses, runners generally yield to both. It’s just easier for us to step aside than it is for a cyclist to stop or a horse to navigate around us. Horses especially can spook easily in the fall when there’s more rustling in the leaves… stopping, staying calm, and letting them pass is always the safer call for everyone.
Get Out There While It’s This Good
That was a lot, I know! But I hope it leaves you feeling ready to get out there this fall.
Because honestly the trails in October are something. The colors, the air, the quiet… it’s one of my favorite things. Between adapting to the terrain, dressing for the temperature swings, staying fueled and hydrated even when you don’t feel like it, keeping safety in mind as the days get shorter, and respecting the trail and everyone else on it, you’ve got everything you need for a great fall run.
The window is still open. Go use it. ♥️
With love, Coach Nik
