If you’re a larger breasted runner, finding a sports bra that’s comfortable, eliminates bounce and doesn’t cause chafing is arguably just as important as finding the best pair of running shoes for your feet.
While the best sports bras for running can vary from compression to encapsulation style depending on a person's breast size, the ideal sports bra bra for bigger breasts tends to be a combination bra; combining the qualities of encapsulation and compression into one. Because, let's face it ladies: medium-support simply doesn't cut it here!
But which bras are actually worth your buck, and aren't going to dig in and chafe over the longer miles? The larger-busted members of the RW team have been putting a number of high-support bras through their paces (quite literally) to bring you our pick of the ones that you'll genuinely want to wear, mile after mile.

How should a sports bra fit?
Mari Thomas, fonder of Maaree bras, says the most important factor when it comes to choosing a sports bra is making sure the underband is nice and snug. 'At least 80% of women are wearing the wrong size bra, and a lot of the time it’s down to the underband not being tight enough,' she says. Another issue is the cup size not being large enough.
With a high impact bra, you want to pay attention to the fabric, adds Thomas. 'You want the bra to have as little stretch as possible in the front, because if the fabric is allowed to stretch then your boobs are going to stretch.'
According to Thomas, the mistake a lot of women make is that they get measured 'that one time in their teens and that’s the size they’ll stick with for the rest of their life'. She suggests treating bra shopping like jean shopping: 'Go with a rough size for yourself, and don’t assume you’re the same size in every shop.'
How to measure your bra size at home
Get a tape measure and, with the inches side facing outwards, put the tape the whole way under your bust, making sure the tape is nice and straight the whole way round. ‘You want to pull it so it’s fairly snug,’ says Thomas.
This measurement is your band size. If you’re an odd number (e.g. 33), you'll want to go up to the next even number (e.g. 34).
Next, go around the middle of your bust with the tape measure – this time, don't go as tightly. 'It’s helpful if you’re wearing a bra too, so that everything is lifted into the position it should be,' says Thomas.
Now, take this second measurement and minus it from your underband measurement. If it’s a difference of 1, you’re an A cup; a difference of 2, a B cup; a difference of 3, a C cup, and so on.
With moulded cups (like the UA Infinity bra below) you'll tend to want to go a cup size down, says Thomas.
The best sports bras for runners with larger breasts
Testers described Sweaty Betty's ultimate high-support bra as 'an absolute game changer'. Wide adjustable straps with a hook-and-eye closure at the underband and quick-release top clasp provide a secure and supportive fit, while an anti-bounce design ensures breasts stay firmly in place without feeling squished. The sweat-wicking fabric is soft and smooth, and there's nine different colours to choose from.

The first thing you notice with this bra is the luxurious lycra-like feel of the fabric, which impressed our tester, given it retails for under £30. It was also one of the easiest bras to get on, thanks to its front-facing zip and hook-and-eye closure. The overall effect is one that almost hoists the breasts up, rather than strapping them down.
This isn't a problem, but if you're ditching your running top it might leave you feeling more exposed. The straps are fully adjustable, and slightly wider than some of the other bras we've tested. Our only issue was that it felt like there was an excessive amount of material around the cups themselves, which reduced breathability over longer distances.

The Power bra might not win many awards when it comes to style, but in terms of supportiveness it does a superb job. A lot of the bounce-free support comes from the wide underband, and there’s not one, but two hook-and-eye closures on the back, along with adjustable straps, so there's plenty of leeway to find a comfortable fit. The cups are moulded (no annoying removable pads here), but not so much that you need a really ‘full’ bust to pad them out. We’re also big fans of the fabric, which feels super soft and keeps us dry, even on warmer days.

Maaree Solidarity High-Impact Sports Bra

Maaree Solidarity High-Impact Sports Bra
Right, bold claim incoming: this might just be the most supportive sports bra our e-comms editor has ever tried. Sure, it’s not cheap. But when you consider the quality and technical elements that have gone into it, we can see why. The hero is the overband - an adjustable panel that runs over the top of the breasts, in order to reduce upward motion. This, coupled with a snug underband, holds the breasts firmly but comfortably in place. We’re talking zero bounce.
We would recommend getting an online fitting to make sure you order the right size, however, as the band does run small. The wide straps are also super comfortable, and convert between a H-back or racerback style for extra support.

M&S Goodmove Extra High Impact Serious Sports Bra
Don’t fancy shelling out big bucks on a luxe design? Consider this affordable bra from good old M&S, which doesn’t mess around when it comes to performance.
Adjustable straps, wiring and a quadruple hook-eye fastening provide next-level support and bounce protection, while moisture-wicking technology promises to keep you cool and comfortable as you get your sweat on.
‘It’s my new favourite sports bra,’ said one happy tester.
The sizing was very hit and miss with this bra, though, so we’d recommend ordering a few to try. But all in all, a brilliant budget buy.

Designed specifically for running, the Energy Bra offers the high support and bounce control you would expect from a high-impact from Lululemon - but what really sets it apart is how comfy it is to run in. It doesn't ride up and the adjustable straps across the back mean you can get the fit exactly right. This bra's sturdy and stretchy double-cross back straps, coupled with its wide comfy back band, featuring a three-step hook-and-eye closure, make it an excellent choice for women with larger cup sizes.

Another great option from Sweaty Betty, this high-impact bra has fully adjustable straps, a hook and eye fastening for easy on/off, plus quick-drying fabric and breathable mesh panels to keep the skin cool and sweat-free. 'I didn’t feel at all overheated during my run and the bra didn’t stick to me after my workout,' confirmed one happy tester. Other plusses include soft padded straps, carefully placed seams and silky-smooth fabric for ultimate comfort. Top tip: size up as we did find the band a little tight around the chest.

Looking for high-impact support without the squish? With research finding that your breasts move in a figure of eight motion when you run, the PeBe Impact Sports Bra features a unique figure of 8 looped contour layer called WRAPA® technology. This is designed to work with your natural movement to support your breasts.
Our tester reported feeling like their breasts were supported and bounce-free, without the ‘crushing’ sensation that some other high-impact sports bras can create. The bra itself is very rigid, with pretty much zero stretch. While this is ideal for support, it won’t be for everyone and it does mean you need to take extra care in making sure you’ve measured yourself correctly as there’s no give. Our tester is in between sizes on the ribs and found opting for the size up provided the best fit.
The bra fastens by a hook-and-eye closure on the back, and then adjustable strap clasps at the front – this makes the PeBe a lot easier to adjust than other bras and means you can easily switch from racerback to standard straps.

Under Armour Infinity High Sports Bra
Now 50% Off
Our tester has run a couple of marathons in UA’s Infinity High bra and it's excellent. The bra was designed in tandem with the University of Portsmouth to work around the way that breasts move while in motion. Whereas most sports bras are made by cutting two breast-shaped cups from flat padding, then gluing and layering pieces of foam on top, the Infinity High bra injects the foam with liquid to create a natural shape that is supposed to move with the figure-8 pattern of the breasts. Combine this with an open crossback design, adjustable straps and easy hook & eye closure, and you’ve got a super comfortable bra that offers maximum support. Our only real criticism is the minimal range of sizes, which could make it tricky for those in between sizes to find a secure fit.

Shock Absorber Ultimate Run Bra

Shock Absorber Ultimate Run Bra
Shock Absorber's Ultimate Run Bra has accumulated something of a cult following over the years, particularly among the larger-breasted running community. Though be warned: sizing can be hit and miss. In fact, Shock Absorber recommends sizing up, and we'd agree - both on the band and the cup. But it's worth going through the trouble to get the correct fit, because this is another quality bra that keeps your breasts firmly in place. It does up in two places - the rear back band and between the shoulder blades - so you feel extra secure. The fabric is silky soft too. It's just perhaps not the most stylish sports bra in this round-up (despite the release of poppier colourways).

Adidas FastImpact Luxe Run High-Support

Adidas FastImpact Luxe Run High-Support
The FastImpact Luxe from Adidas is an unusual design: it pulls on over the head like a compression bra, but instead of a traditional hook and eye closure, it has swan hooks on the elastic chest band and straps. This allows you to customise the fit and shape. Full disclosure: it’s not the easiest bra to wriggle into. However, once it’s on, the breasts are held firmly in place and the silky material has a comfortable lycra-like feel that wicks away potentially the best of any of the products in this line-up.

Yes, we know this bra expensive, but if we're choosing between poorly supported, chafed breasts, and investing in decent support, we know which one we'd go for. The Battle Bra is the newest release from Maaree, and uses an underwire and moulded cups to create a more pleasing silhouette with defined separation between your breasts. For this reason, it's perfect for women looking for a bit of a lift. The same overband technology from the Solidarity bra is integrated into the design too. A warning though: we'd almost certainly recommend an online fitting - or even two - to make sure you get the right size for this one. We found the underband came up a lot smaller that with Maaree's Solidarity bra, and the same for the cup size too.

Panache Sport Ultimate Non-Wired Sports Bra

Panache Sport Ultimate Non-Wired Sports Bra
If you're above a D-cup but can't stand underwired sports bras, you'll like Panache's Ultimate Non-Wired bra. The cups are moulded, so you don't have to worry about any removable pads, and it's a seam-free design to help minimise chafe.
The bra uses a traditional three hook-and-eye closure and then, similarly to other bras in this guide, there's an optional J-Hook on the shoulder straps if you want additional support. We found the bra was fine left as a H-back for gym-based strength and conditioning, but we needed the additional support from the J-Hook for running. Also note that the band size does run slightly small - we opted for a 32, rather than our usual 30 size, and found it provided the right level of snugness. The cups run true to size, though, so opt for your regular size.
The overall design isn't anything to write home about, but this isn't a massive issue if you're wearing a vest or t-shirt over the top. If this is a dealbreaker though, the bra is available in a funkier pattern.
