Let me paint you a picture.
It’s early July. I’m three minutes into my run and already I can feel it. My shorts are riding up. The fabric is sticking to my inner thighs. By minute five, the chafing has started and I am now fully distracted from every single thing about this run except the burning sensation between my legs.
I went home, changed, and never wore those shorts again.
Here’s what I know now that I wish I had known then: the secret to surviving summer runs as a curvy runner is not about toughening up or pushing through discomfort. It’s about wearing the right things for your actual body, not the body the running industry designs most gear for.
This is what I wear. This is what works for me. And if you have thick thighs that touch, hands that swell, and a forehead that sweats before you’ve even hit the end of the driveway, this post is for you.
Let’s Talk About Shorts (And Why I Don’t Wear Them)
I know shorts are the default summer running recommendation. Lighter, more airflow, cooler. And for some people, that’s true.
I am not those people.
My thighs are thick and they touch, and no matter what shorts I tried, the result was the same: riding, bunching, sticking, chafing. I spent a long time thinking I just needed to find the right pair. Eventually I accepted that shorts and I are simply not compatible on a run, and my running life got significantly better once I stopped fighting that.
If you’re in the same boat, please know you are not doing anything wrong. Your body is not the problem. The recommendation is just not built for us.
What I wear instead are capri leggings, and I will explain exactly why that works better than you might think.
Why Capri Leggings Are My Summer Running Non-Negotiable
I know what you’re thinking. Leggings in the summer? Aren’t you dying?
The answer is: not if you choose the right pair.
The key is a lightweight, moisture-wicking technical fabric that actually breathes. Not the thick compressive leggings you wear in October. Not a cotton blend. A proper running capri in a thin, fast-drying fabric that pulls sweat off your skin and dries almost instantly.
For me, capris hit the sweet spot. Full leggings can feel like too much in peak heat, but capris give my thighs the coverage and compression they need to stay chafe-free while leaving my calves free to breathe. Now, long biker shorts are the one exception I’ll mention. A 10-inch inseam gets you close to the same coverage, and some runners love them. The honest reality though is that many still roll up on thicker thighs mid-run, and constantly stopping to pull them down is its own kind of annoying. That’s exactly why I keep coming back to capris. They stay put.
I have a few pairs I rotate through all summer. These are my absolute favorites! What to look for on any label: words like “moisture-wicking,” “Dri-FIT,” “Swift,” or “fast-drying.” Avoid anything that says “cotton” or “jersey.” In summer heat, those fabrics absorb your sweat and hold it against your body. That’s the opposite of what you want.
Let’s Talk About What’s Going On Underneath
Okay, we’re going there. Because nobody else will and somebody has to.
I sweat. Everywhere. Including down there. And if you’re a curvy runner who runs in the heat, you know exactly what I’m talking about. You finish a run, you look down, and it looks like you completely peed yourself. Not a great look in the grocery store parking lot.
The fix that changed everything for me: padded moisture-wicking underwear designed specifically for this situation. Not your regular cotton underwear. Not going commando and hoping for the best. Actual technical underwear with a built-in pad that absorbs moisture, keeps you dry, and means you can walk back to your car after a summer run without feeling like you need to explain yourself to strangers.
It stays dry, it doesn’t bunch, and it works with your leggings instead of against them. Honestly one of the most underrated additions to a summer running kit and the one thing nobody puts on their gear list.
You’re welcome.
You Need Anti-Chafe Balm. No Exceptions.
Even in the right leggings and the right underwear, I apply anti-chafe balm before every single summer run. This is not a sometimes thing. This is part of getting dressed.
Thighs, underarms, anywhere your bra band sits, anywhere fabric meets skin repeatedly for 30 or 45 minutes. Chafing in summer is faster and more brutal than in cooler weather because sweat changes everything. A spot that was fine in April can be a raw, stinging mess by July if you skip this step.
My approach: leggings on, balm on, then I walk out the door. In that order, every time. Here’s my favorite anti-chafing balm.
If you haven’t made this part of your routine yet, start today. You will wonder how you ever ran without it.
The Sports Bra Has One Job: Keep You Supported and Comfortable
For curvy runners, the sports bra is the most important piece of gear we own. In the summer, it also becomes a heat and comfort issue in ways it isn’t in cooler months.
What I look for in a summer running bra: genuine support (not just compression that restricts your breathing), soft breathable fabric that doesn’t feel scratchy or stiff against sweaty skin, and a design that allows some airflow across your back and under your arms. Bras with mesh panels or an open back design make a noticeable difference on a hot run.
I have one I keep coming back to every summer because it checks every single box. [Amazon affiliate link] It does not move during a run, the back design helps with airflow, and it comes in a wide size range, which is always something I check before recommending anything.
A bra that fits well, feels soft, and stays put is one less thing your brain has to manage out there.
The Tank Top Situation
I wear a tank, not a tight one. A fitted-but-not-skin-tight tank in a breathable fabric lets air move around your body without the top bunching or riding up while you run.
What I look for: a relaxed fit through the body, a long enough hem that it stays over my waistband, and wide enough straps that they don’t dig into my shoulders or interfere with my bra. Lightweight polyester or a polyester-nylon blend is what you want. It feels like almost nothing on your skin and dries in minutes.
Avoid anything that feels remotely heavy in the store. If it feels thick before you’ve even started sweating, it will feel like a wet blanket by kilometre two.
The Hat Is Non-Negotiable When You Sweat Like Me
I sweat from my forehead. Profusely. Within the first few minutes of any run, and significantly faster in the heat. Without something on my head, that sweat runs directly into my eyes and it is both uncomfortable and genuinely disruptive to my run.
A running hat is my go-to. The brim catches the sweat before it reaches my eyes, and a hat with mesh panels on top lets heat escape from my head rather than trapping it. In summer, that heat escape matters. If a full hat feels like too much, a bandana tied around your forehead works just as well to keep the sweat out of your eyes and costs almost nothing. Either way, your eyes will thank you.
Mine goes on my head the same way my shoes go on my feet. Not optional, just part of the kit.
Hydration Starts Before You Walk Out the Door
This is something I do every single time and I think it’s one of the most underrated things you can do as a summer runner.
I hydrate before I run. Not just a sip. I drink water intentionally in the 30 to 60 minutes before I head out. By the time your body tells you it’s thirsty, you’re already behind. In summer heat, that gap closes faster than you think.
I also bring water with me on every single run, no matter the distance. My go-to is a running belt with a water bottle attached. My hands stay free, I don’t have to think about stopping at a fountain, and I can sip whenever I need to without breaking my stride. For shorter runs, it’s all I need.
When I’m going longer and need to carry more, I switch to a running vest. Yes, it’s warmer than the belt. I won’t pretend otherwise. But it lets me bring significantly more water, fit my phone, my gels, my keys, and anything else I need for a longer effort, all without it bouncing around or throwing off my stride. On a long summer run, having everything I need right there with me is worth the extra warmth.
On those longer runs I’ll tuck an energy gel or a waffle into a pocket, and I add an electrolyte packet to my pre-run water when it’s really hot. Electrolytes help your body actually hold onto the fluids you’re taking in instead of just flushing them through.
Hot weather means you’re sweating more and losing fluids faster than your body is signaling thirst. Don’t wait until you feel it. Just drink.
Putting It All Together
Here is my actual summer running outfit, start to finish.
Moisture-wicking padded underwear. Lightweight moisture-wicking capri leggings. Anti-chafe balm applied before I leave. A supportive soft breathable sports bra. A relaxed-fit moisture-wicking tank with a long hem. A ventilated running hat or a bandana if that’s more your speed. Running belt with water for shorter runs, vest for longer ones. And a solid round of hydration in the hour before I even step outside.
That’s it. That’s what works for a thick-thighed, heavy-sweating, curvy runner who spent way too long figuring this out through uncomfortable trial and error.
You don’t have to go through that part. Start here.
P.S. Everything I run in is linked on my Amazon shop in this list. I only recommend gear I’ve actually worn in my actual body on actual runs. If you’re looking for my Lululemon picks specifically, those are over on my LTK page. Go build your summer kit.
