Few things are more uncomfortable than a sports bra that doesn’t offer enough support when you’re on the move. The last thing you want is a strap that won’t stay put, sweat pooling under your chest, or a bra that requires an army to wrestle off after a run. Ideally, you want something that looks good (because, let’s be honest, style matters too – especially in summer when running shirtless is always an option), while still delivering the support, flexibility and comfort you need.
Thankfully, although you’ll often pay a premium for it, finding a sports bra that ticks all those boxes isn’t too much to ask. Last year we put the best running shorts to the test, and now it’s time to give sports bras their moment in the spotlight.
To help you find the right one and avoid wasting money on disappointing options, we tested some of the most popular sports bras on the market. We wore them on everything from easy 5K runs around the neighbourhood to longer 15–20km training sessions, including plenty of miles in scorching summer heat, to see how they performed when it mattered most.
Alongside our favourite picks, we’ve also included the sports bras that didn’t quite live up to expectations. Of course, fit and comfort are personal, so your experience may differ, but these are the models we wouldn’t recommend based on our testing.
How we tested these running bras
We tested these bras on real runs of different distances and effort levels, from short easy runs to longer sessions where support really matters.
We looked at how each bra performed while running, focusing on support, bounce control, and whether it stayed in place without needing adjustments. Comfort was judged during movement, especially around the straps, seams and underband once sweat built up.
We also checked how the fabric handled heat and moisture during the run, and how it felt by the end. Ease of getting the bra on and off was also part of the test. Some bras are fine once they’re on, but after a sweaty run they turn into a bit of a wrestling match to get off, which quickly puts them in the “never again” pile.
The best running bras for women
1. Panache Sport Underwired Sports Bra
Panache uses a firm, structured fabric blend (polyamide, polyester and elastane depending on colourway) for maximum stability. The cups are fully moulded and encapsulated with an internal underwire frame, which gives each side separate support rather than compression.
Everything feels held in place during the run, even if you pick up your pace. The fabric itself is quite dense and smooth, with limited stretch compared with softer seamless designs, which adds to the secure feel but reduces flexibility slightly. Moisture is managed reasonably well, though it can feel warm on longer runs due to the heavier construction.
The straps are padded and adjustable, and the band is firm, which helps stability but makes the overall feel quite rigid. It is not a soft or relaxed bra, but it is extremely dependable for high-impact running.
Price: £48
2. Fabletics No-Bounce High Impact Sports Bra
Here comes your trusty one – this Fabletics model is perfect for running, HIIT and other high-impact workouts. Made with 19% spandex, it’s all about compression and stability; arguably the two things most runners are looking for in a sports bra.
The high neckline and wide underband don’t just provide great coverage; they keep everything feeling secure when you’re on the move. Although it doesn’t feel quite as airy as some running bras, the moisture-wicking fabric coped well, even on warmer (or shall we say infernally hot?) days and higher intensity runs (like fartleks). And can we take a moment for the back? The multi-strap design is gorgeous.
Lastly, one of the biggest wins is the colour selection. Fabletics offers loads of different colours and prints, so you’re not stuck choosing between black and grey. The only downside is that everyone else seems to love it too. Popular colours and common sizes sell out fast.
Price: £69
3. Shock Absorber Ultimate Run Sports Bra
Shock Absorber uses a high-compression performance fabric (nylon/elastane blend) to minimise movement through tight structural hold. The material feels dense and supportive, with very little stretch once you put it on.
It’s very compressive across the whole chest, supported by a reinforced underband and adjustable straps. During running, the fabric feels very secure and keeps everything stable, even if you want to pick up the pace. The trade-off is comfort – the material feels quite firm against the body and doesn’t have much give, which becomes noticeable over longer runs (10km+). Breathability is moderate, but the tight compression can feel warm when intensity increases. It is a very controlled, structured bra that prioritises stability over comfort.
Price: £52
4. Brooks Dare Racerback Bra 2.0
The Limitless Racerback is one of Brooks’ most structured high-support bras, and it shows the moment you put it on. The shape is built around moulded cups that don’t just compress the chest but actively define and separate it, which gives a noticeably more “held” feeling than simpler racerback designs.
That structure translates into control when you’re out on a run – the movement feels contained and more stable over distance than softer, stretch-led bras. There’s less of that gradual “loosen and shift” effect you sometimes get once sweat builds up and the fabric warms through. The straps and back adjustment system do more work than you expect. Once set properly, the bra doesn’t really need touching mid-run.
Price: £55
5. Triumph Triaction Energy Lite Sports Bra
If you prefer support without feeling like you’re wearing body armour, the Triumph Triaction Energy Lite is well worth a look. Unlike some high-impact bras that rely purely on compression, this one uses lightweight spacer cups to give you shape while still keeping bounce under control. The result is a bra that feels supportive without flattening your chest.
The fabric is soft against the skin, the padded crossover straps don’t dig into your shoulders, and the wide underband stays put without feeling restrictive. We also loved how breathable it felt on warmer runs. The mesh panels and spacer cups allow plenty of airflow, so even during longer sessions it never felt hot or heavy.
The bright colour options (Bubble Gum Pink, hi Barbie!) are a welcome change from the sea of black and burgundy you’ll find elsewhere. Our only criticism is that it is definitely more lightweight than the average running bra, so you’ll need to make sure you choose the right cup and band size for it to work properly.
Price: £46
6. Hastko Sports Bra no.39
The Hastko All-Terrain Sports Bra is one of the most comfortable sports bras we’ve tested, we suspect due to its heat-welded construction that creates a smooth, second-skin feel.
We wore it in various runs and experienced virtually no chafing around the underband or shoulders – something we can’t say for many of the other bras we tested. The seamless underband and flat straps stay in place throughout your run, and the breathable cups offer support without adding unnecessary bulk. It’s also refreshingly flattering – and doesn’t make your chest look like a deflated pancake!
If you prefer a very compressive fit, you may find it allows slightly more natural movement than some traditional high-impact sports bras. For us, though, that struck the right balance between support and comfort.

The worst running bras for women
1. Sweaty Betty Runner’s High Zero Bra
No need to break a sweat browsing Sweaty Betty’s running bra range – the high-support options are fairly limited. Even so, we wanted to give it a fair test, especially as the Runner’s High Zero Bra pop up in other round-ups, so we bought it in. First impressions: it looks solid and structured, almost like armour, but that doesn’t really translate once you’re actually running in it. Sweaty Betty calls it “ultra-lightweight,” but it doesn’t feel especially breathable when you start sweating. On longer runs, it can feel a bit damp and uncomfortable. The only positive is that the straps are adjustable, so you can make it fitted.
Price: £60
2. Sweaty Betty Stamina Seamless Sports Bra
Despite being notably cheaper than the first Sweaty Betty bra we tried (if that’s ever an excuse), this model is still not worth the price tag for us. It might be suitable for yoga and light gym sessions, but it’s definitely not supportive enough for high-impact exercise, especially above a C cup, unless you’d want your boobs to be bouncing up and down as you run. A lot of consumers state inconsistent sizing as a key negative, and we found that as well – it’s a very tight fit, so if you do want to give it a go, make sure to order up to two sizes down. Generally, quite a big miss from the brand.
Price: £35.00
3. Lululemon Energy Bra
This particular bra has earned a loyal following as a lifestyle sports bra (whatever that means), but we found it falls short where running is concerned. While the compression-style design offers a comfortable, streamlined fit for gym sessions and lower-impact workouts, it struggles to provide the level of bounce control needed for regular running, particularly over longer distances.
During faster-paced or interval runs, the bra can feel less secure than specific running models, and the lack of structured encapsulation may leave runners with larger bust sizes wanting more support. Although the soft fabric and attractive design make it versatile, there are many stronger options available.
Price: £58
4. Gymshark Ruched Sports Bra
The Gymshark Ruched Sports Bra delivers on style, but we found that aesthetics have been prioritised over performance. The lightweight construction and fashion-led design make it comfortable for casual workouts, yet they don’t provide the high-impact support most runners require.
During the few runs we managed to clock in wearing this bra, it offered limited bounce control and felt less secure. While it may be suitable for strength training, or short, low-intensity sessions, runners looking for dependable support are likely to find it lacking, especially if they regularly log higher mileage.
Price: £28
5. Under Armour Crossback Mid Sports Bra
The Under Armour Crossback Mid Sports Bra is marketed as a medium-support option, and the brand isn’t lying. The problem is: very rarely is mid-support enough! For general fitness activities, it offers a comfortable fit, soft fabric, and good freedom of movement. However, when used for running, it didn’t provide the level of support we need – and that’s dealbreaker number 1. The simple compression design can allow more movement than dedicated running bras, and those with larger bust sizes may find that support diminishes as intensity increases. While it performs well within its intended category, it is not the first choice for runners looking for maximum comfort and confidence on the move.
