Here's the trail running gear we're wearing in Fall 2026

It's fall, y'all

Some of y’all can feel it. At 8,400 feet, it comes a little early. So, excuse me for jumping in with all the goodness of fall. It really is one of the best seasons to be a runner.

It can also be a difficult one to prepare for any run.

Long sleeves or short sleeves? Gloves or bare hands? Or bear hands? Do I head out of the house hoping for the sun to magically appear, or do I bring a headlamp? What do I do about the moisture falling from the sky?

Even with all of the added worries about what to wear, this is our favorite running season.

Here’s some of the stuff we’re enjoying right now.

Clothing

TAYLOR: My main goal in life is to spend as many hours in either running clothes or flannel. Often, my wardrobe includes both, and I’m proud of that.

As cool fall mornings and evenings are consistent, the Rabbit High Country Flannel Lined has been my extra layer for… well, everything. Getting groceries, grabbing firewood, commuting to the trailhead, sipping wine on the deck with my wife at the end of the night, and keeping myself at a comfy temp throughout the day because I’m too dang stubborn to even think about turning the heat on before October comes around.

Honestly, though, if you see me from now until the new year, I’ll likely be sporting this. I might as well pick up a couple of other colors.

TAYLOR: Talk about being made for the season! The Janji Repeat Merino Long Sleeve was created for this season when we have no idea what season it actually is. Whether it was a crisp morning or the run got warmer than anticipated, this layer showed up.

I am a sucker for a good merino blend like this for multiple reasons, including moisture management, odor management, and temperature management. What sets the Janj Repeat Merino Long Sleeve apart is that it is truly comfortable. There’s no itchiness; it’s not heavy or too light, and it has a standard fit that doesn’t scream baselayer.

Wear it on its own or use it as a true base layer. You won’t be sorry with this one.

RENEE: Yes, the Tech Shirt is a $93 shirt, but in its defense, the item is marketed as “performance meets confidence.” Confidence isn’t cheap. The shirt is for runners who want a travel/casual shirt that doubles as running apparel. Also, the buttons and logo glow in the dark, so you get that fun factor too.

Functionally, the shirt is breathable, not only through the button slots but also in the actual material, which is lightweight with a grid fabric. I ran hill repeats during the humidity of August (before going to work) and found the breathability excellent. If the photo of me wearing this shirt is featured in the review, you can tell by my face that I ran a hard workout in the heat, with the thought of work now on my mind. But at least I looked fashionable in this $93 shirt. Or maybe I didn’t, but the shirt itself looked good.

The material is not heavy, so the technical functions deliver. Stylistically, the Tech Shirt looks ready for socializing more so than running. The shirt is men’s-only sizing and very much a men’s fit. I normally wear a women’s size small and reviewed an XS in the Tech Shirt. The shirt is long and fitted. For running, the shoulder/chest area was a bit restrictive, but that’s more of a gender-fit issue than a sizing issue. Most women should be able to size down in this shirt. For men, the length is long, so if you don’t need the volume across your back and chest, you might be able to size down as well.

TAYLOR: Wool is the OG superfabric that I wear two-thirds of the year faithfully. Fall is really the kickoff to sporting it, and the Icebreaker Merino Blend 125 Cool-Lite Speed Tee is one of my favorites for this unique job. You see, Fall is really just a constant tug between summer and winter. I appreciate how this layer can handle the warm days on its own with its lightweight, extremely breathable, and antimicrobial benefits. It works just as well as a base layer under a light jacket. It’s simply one of those pieces I will grab at any time of year and be satisfied with its performance.

SAM: I’m fully a running belt convert. I wear a belt on basically all of my runs. It's just easier to keep a phone and keys there, and if I need to shove water or fuel in too, everything just works out. So of course I was stoked to get to try out a pair of lightweight half tights that have what is essentially my beloved Naked belt incorporated into the waistband. 

The Apex Trail Half Tights are a thin and very light (about 100g), speed-focused short with a 4-pocket integrated running belt in the waistband. They have two small elastic mesh side pockets (fuel, cards, keys), a zippered rear phone pocket, and a large elastic mesh front pocket that works for almost anything. I stashed plumbing fittings for my job in there along with some snacks during test miles.

Thin Lycra stays in place thanks to sticky cuff linings, and a drawstring keeps everything from sagging. These half tights are straightforward and fast with plenty of storage. If you're between sizes, I'd recommend sizing down, just to keep the belt up more. There aren't many gripes here, as they held everything without me ever worrying about something falling out, but they could definitely use a key clip so that I'm not double-checking my keys every half mile.

JOHNNY: The Aerolight Wind Jacket is an exceptionally lightweight layer that packs down neatly into its own pocket, making it easy to stash in a running vest when conditions are unpredictable. I particularly appreciated some of the thoughtful design touches, including the subtle S-shaped rear vent and the branded hood pull tab, which gave the jacket a premium feel without adding unnecessary complexity.

Performance-wise, the jacket does exactly what you'd expect from a lightweight wind shell, providing welcome protection from cooler breezes while remaining highly packable. The fit, however, felt more relaxed than I'd typically look for in a dedicated running jacket. I tested a medium and found it quite boxy through the body, with sleeves that ran a little long. I suspect a small would have provided a more streamlined, performance-oriented fit.

My main gripe was the cuff design. With elastic only on one side of the cuff, the sleeve regularly crept over my GPS watch, meaning I often had to pull it back to check my pace during runs. It's a small detail, but one that became noticeable over longer outings.

Overall, the Aerolight Wind Jacket feels more like a lightweight mountain or hiking layer that also works for running, rather than a jacket designed exclusively with runners in mind. That said, if packability and low weight are high on your priority list, it's a compelling option.

TAYLOR: Dual-purpose is an ultimate mark of practicality. A lot of my sun hoodies for summer become long-sleeves for fall and winter. They still protect me from the sun’s rays and add a light warming layer (with a hood) for the cool mornings.

I kid you not, I got rid of three other sun hoodies after wearing the Fractel S-Rockies Sun hoodie. It is a beautiful mix of protection, comfort, and runner-minded function. Complete with a cinchable hood, watch windows, and a semi-cropped torso, this thing is ready for multiple seasons of wear.

Bonus points for the limited edition paying homage to my home. I heart the Rocky Mountains!

TAYLOR: I struggle with appropriate layers, especially in these transition seasons. While this jacket can easily be put into the winter roundup, I find it appropriate here too.

I’ve used the Nike ACG Lava Flow Jacket for just about everything outdoor-related, and I have found myself grabbing it over previous favorites that are at the ready by my front door. It’s an extremely lightweight layer that packs a powerful punch with its 1,000 fill power down. While it might be meant for less aerobically challenging endeavors, I’ve definitely put it through a few adverse circumstances and still vouch for its dependable warmth and construction.

I've done so much in the ACG Lava Flow, and I approve of all of the following:

• Warm-up miles on cool mornings before dropping it at the car
• Cool bike rides
• Hiking
• Drinking coffee on the deck pre-run
• Cold weather runs
• Staying warm post-run after sweat dries and cools

Really, this jacket has a lot more capabilities beyond running, but I like that it can easily be integrated into that part of my life too.

PACKS AND BELTS

TAYLOR: The Tantrums Crest 6 was already one of our favorite pieces of gear ever. The airy build, function-forward pockets, and top-notch fit are all notable. What makes this version better is that it simply levels up the quality fit even more.

The outer material was replaced to be more durable on the pockets and rear panel. The construction of the rear panel was also adjusted for greater carrying capacity. My favorite update was to the inner construction of the pack itself. Essentially, it was given some stout tendons that are intended to provide more structure and durability to the Crest 6. While it’s still a flexible running pack that is lightweight and moves with your body, it’s not flimsy.

The updated Tantrums Crest 6 was my pack of choice for MCC during UTMB week, and it reclaimed its spot as my trusted race-ready pack among the masses.

RENEE: I wrote at length about the W LF 2L belt in our review. Looking back, I basically wrote a novel about this belt. And for good reason. I’ll spare everyone the details and defer to my review if you need the specifics. I’ve been wearing the belt for my daily runs after review, reaching for this instead of my numerous vests and other belts I have for review. If you dislike having to shimmy on a tight belt over your hips, this belt is for you. 

The capacity won’t work for every long run, but for 650ml of water, a phone, and a few hours of snacks, the belt has plenty of storage. For fall and winter runs, I’ll need even less water/fuel. The belt is pricey, but it’s proving to be an all-season gear item.

ACCESSORIES

TAYLOR: I’ve gotta admit that my makeshift paper funnel or hand scoop isn’t always the most accurate or sanitary option for fueling on the go. Can anybody else admit to this? The Hydrapak Fuel Kit is one of those “no, duh!” type of accessories that made an immediate impact on how I do things.

Hydrapak’s Fuel Kit has everything needed for race day, trips, or the weekend long run to help organize and execute fueling. We’ve all been in the scenario of trying to pour in drink mix by the waning light of our headlamp so a buddy can achieve their goals. Or maybe you’re doing it for yourself and spill half of the powder on the rim of your bottle. The sticky residue reminds you of your mishap the rest of your run. There’s no second-guessing or regret with this kit. Throw on the funnel, measure out precisely what’s needed, and don’t make a mess in the process.

Because it’s also in a nice carrying kit, I don’t have to hunt around for each piece of equipment before heading out the door. All I need to do is grab the kit, add some fuel, and be on my way. This is a great grab for anyone who frequently races or uses theirs as an aid station.

RENEE: New styles of the Wide Open Socks drop in October, just in time for fall adventures. For years, I’ve included Darn Tough Socks in my favorite apparel lists, and I’ve never received them for free. Yes, that’s right: we don’t always get gear for free. 

Wide Open Socks have more stretch, which I find more comfortable for daily use. I wear these socks to work; I’ve backpacked with them, hiked in them, and run in them. I’ll still prefer a tighter sock for long trail runs, but for everything else, I’ve been reaching for my WO socks. I don’t have wide feet or ankles; I simply enjoy the comfort and stretch of these socks when I’m on my feet all day. The new knee-high socks have 57% Merino wool, which will be great for cold running days.

TAYLOR: Orange is the new black…especially during hunting season. While I have a few hats I’ve used for years to be seen on the trails while there are gun wielders in the vicinity, they are cheap and fit funny. 

The Melin Odysea Mac Nomad Thermal Cap may just be the opposite end of the spectrum on all of those points. It’s a spendy hat for running (or hunting), true. Quality and broader wearability is the bonus, though. This will be a cap you can put through wringer in the great outdoors,, dust it off and wear it for the rest of the day in style.

The waxed ripstop material is incredibly durable, resists the elements, and holds some structure for style points. It’s really a versatile cap that’s perfect for the full gamut of fall activities.

TECHNOLOGY

TAYLOR: Like shoes, the recipe for tech watches in endurance sports has basically been figured out. Amazfit has a wide range of sport watches that can be a solid companion; however, the T-REX Pro 3 is their most adventure-focused model.

It has a lot of the same GPS and map capabilities as the Garmin Forerunner series, Suunto Race series, and Coros Pace series, with a lot of other bells and whistles. That also includes a long battery life compared to those options, with a 38-hour window in full GPS mode. Military-grade durability makes the T-Rex Pro 3 even more enticing. How about the fact that this is Ruth Croft’s go-to watch?

Admittedly, the Amazfit T-REX Pro 3 hasn’t been a standout option compared to the other brands, but it is a competitive option that comes in at $399.

We’ll have a full review ASAP.

TAYLOR: How did I even find myself with this thing? For someone proud of human-powered travel, I will admit that the Engwe E26 3.0 has become a tool I depend on.

Honestly, I was very skeptical of both the performance of this bike and its ability to become something I use frequently. By golly, it passed the test with flying colors!

It is a beast of a bike that has legitimately expanded my adventure horizons. From commuting to trailheads to pushing the start of my trail runs deeper into the wilderness than ever before to even hauling firewood for my family - there are a lot of possibilities with such a tool.

My biggest issue with the Engwe E26 3.0 is where to park such a tank. Good thing I have a little bit of time before the weather forces me to think about that too much. For now, it’s parked right outside my door, ready to hit the dirt.

NUTRITION

TAYLOR: Skratch Labs is a staple brand in our nutrition plan for training and racing. While I mostly use their high-carb drink mix during activities, I also need my hydration to perform during the non-running portions of my day.

Skratch Labs Apple Cider is a bright, flavorful drink mix that’s perfect for this early fall season. It provides me with the electrolytes (not just sodium but potassium, magnesium, and calcium too) I need, as well as carbs for pre/post workout. The blend of glucose and fructose has been a proven easy-on-the-tummy formula if you’re inclined to drink this before or during activity.

Here’s a tip: Drink some of the Blood Orange Hydration Mix pre-run and follow it up with a warm Apple Cider Hydration Mix post-run. Fall run nutrition at its finest.

Shop The Hydration Mix 

TAYLOR: I am 100% bought into fueling primarily through my bottles. The main issue is finding drink mixes that have what you need to perform. Some high-carb drink mixes will skip electrolytes or have a wonky recipe that upsets the stomach.

On the shortlist of high-carb drink mixes I trust is Tailwind High Carb Fuel. It really is a one-stop shop for endurance performance nutrition. Per 16-20 oz, it can boast an insane 90g of carbs with 680 sodium, 190mg of potassium, and 60mg of calcium. It really does check pretty much every box I need it to on race day. Sometimes, I’ll supplement with a little extra sodium via pickles or chips, but I’d do that at an aid station anyway.

Even better, while the flavors are potent, the Ginger Lime is especially easy to slurp while on the run. I used this specific product to train for a recent ultra and found it to be a consistent performer that I’ll keep returning to for long runs and race day.
