Chosen By Us: Best Sports Bra for Running in Australia (2026)
We all know running places serious demands on breast tissue. With every foot strike, the breasts are exposed to repeated movement, which is why high-impact support is so important for runners.
As Australia’s only Sports Bra Specialists, we understand what it takes to properly support a runner, not just in the fitting room, but once they’re moving. And after 40,000+ Sports Bra Fittings over the past 13 years we're confident our knowledge puts us in good stead when it comes to recommending the good bras for running.
Why running needs more support than any other activity
Running is a highly repetitive movement. With every foot strike, your body rapidly decelerates and accelerates again. Your breast tissue doesn’t simply move neatly up and down with you. Research from the University of Portsmouth’s Research Group in Breast Health found that during running, unsupported breast movement can reach around 15 cm (Scurr, J., White, J. & Hedger, W. (2011))
That movement is happening stride after stride, kilometre after kilometre. A sports bra for running therefore needs to do much more than feel firm when you first put it on. It needs to control repeated breast movement while still allowing you to breathe, move your arms freely and remain comfortable throughout your run.
And breast movement is far more complex than “bounce”.
In a three-dimensional study, Scurr, White and Hedger found that the breasts move in a figure-of-eight pattern during running, travelling vertically, side-to-side and forwards and backwards. Importantly, 56% of overall breast movement occurred in the vertical direction (Scurr, J., White, J. & Hedger, W. (2009)).
That vertical movement is what many runners recognise as bounce, but controlling only that movement isn’t enough. A high-performing running bra needs to manage the breast in all three planes of movement, which is why design, sizing and fit can make such a dramatic difference.
Did you know that Breast Research Australia found that an 80-minute run generates roughly 12,500 breast movements 😱.
Encapsulation or compression for running?
With two radically different methods to control breast displacement, it's not surprising people get confused about which way to go with a high impact sports bra.
For smaller breasted women, compression style bras are typically favoured for running.
For D+ cup women most people favour sports bras that draw on a combination of both encapsulation and compression in their design. These bras will offer a degree of separation, which also working to compress the breast to chest wall. Most technical running bras designed for a D cup + use both methods, but with varying degrees of each. Some are stronger in their encapsulation and separation; some pay lesser attention to that and apply greater compression.
For those who can't stand their breasts touching each other during a workout, it's essential to be in an encapsulation style running bra.
How a running bra should fit
Three components of your bra fit, that must be done well in a running bra:
✅ The ribcage band needs to be firm, but not overly restrictive. Your running bra should feel firmer than your everyday bras.
✅ Cups need to completely cover breast tissue. A plunge style bra won't block the vertical escape route of breast tissue.
✅ Straps should sit snugly, without being too firm that they restrict upper body movement. Adjustable straps are key to ensure you can maintain the fit over the lifespan of the bra.

Best running bras for larger breasts
Featured in my recommendations above are four of our Bra Fitters’ preferred options for women with a larger bust: the Elomi Energise Sports Bra, the Enell Sports Bra for those who prefer firm compression, the Panache Power Sports Bra, and the Active D+ Classic.
Each of these bras takes a different approach to managing a larger, heavier bust, where breast movement during running can occur with greater magnitude and momentum. For this reason, effective support is not simply about choosing the firmest bra available; it is about selecting a highly technical design that works with the individual’s breast shape, size and preferred support style.
Many fuller-busted women prefer an underwired sports bra because it provides greater separation and definition between the breasts. However, an underwire is not essential for effective high-impact support. A well-engineered, wire-free sports bra can perform exceptionally well, provided the fit is precise and the garment is designed specifically to control significant breast movement.
The Active D+ Classic and Enell Sports Bra are both strong examples of industry-leading wire-free designs. When correctly fitted, they can provide excellent support for larger busts during running without relying on an underwire.
If you are new to running
Starting out? While you don't specifically need a dedicated running bra. You do need to ensure your sports bra is high impact so that it can cope with the demands that running places on breast tissue. The last thing we want is your breasts getting in the way of your new training goals.
A mistake we often see is newcomers trying to get away with only having one sports bra in your rotation. If you are training 4+ times a week, wearing one bra for all four sessions will quickly wear through your sports bra.
We recommend having one sports bra for every two training sessions you do a week. If you are varying your training between low and high impact workouts, then it's ideal that your bras are suited to each different activity demands - this ensures you have a good experience in each of your support solutions.
FAQs
Do I need a Sports Bra for running if i am small chested?
Yes! Small breasted women are worthy of support too. Smaller breasts still displacement (or bounce!) when running. While the magnitude and force behind the movement is lesser, a sports bra still helps to lighten that load and keep our small busted friends moving freely.
How often should I replace my running bra?
Wearing a running bra twice a week, will have it last about 9-12 months. Depending on whether it's treated well during the washing process. If you are wearing one running bra four times a week, you'll find the materials stretch and no longer function much faster.
Does breast movement cause sagging?
There isn't research that can prove unsupported breasts will sag. However, it is widely accepted that stretching the skin of our breasts is likely to occur in an unsupported breast. And the skin is one of the only natural support structured (albeit a weak one) - so we think it's best to not damage it.
Whats the difference between a sports bra and a sports crop?
Sports Crops are non technical, often fashion based garments often mistaken for sports bras. Sports Bras should be lab tested, produced in cup and band sizes, use quality fabrics and have multiple points of adjustability. A Sports Bra will likely be made up of 30+ different unique elements. A sports crop may only be made up of 3-4 different components.
Can a running bra have underwire?
Yes, it's safe for most people to run in an underwire bra. Lots of the D cup+ running bras will have underwire, which serves to separate breast tissue and optimise support in an encapsulation sports bra.
Do i need to wear in my running bra?
We recommend using a new running bra for a few shorter sessions before taking it on a long run. A new bra will always feel a bit firmer and more rigid than it will after a few washes and wears. Like running shoes, it's never a good idea to unleash a new product n a long run or event day.
