How to Pick the Perfect Running Sports Bra: 6 Tips from Hayles & Jussie

Written By Hayley Moody

Hey WRC WOMEN, We are here to support you (excuse the pun) to find the BEST SPORTS BRA possible! Whether you're training for your next 10K, getting back into a groove, or just starting your running journey—there’s one thing every woman needs to feel supported on the move: a great running sports bra.

At the Women’s Running Collective, we know a thing or two about what it takes to go the distance comfortably (and confidently!). Choosing the right sports bra for running isn’t just about style it’s about support, comfort, and making sure nothing gets in the way of your goals.

Here are 6 runner-approved tips to help you find your perfect match.

1. Know Your Size (Yes, Really Know It!)

One of the biggest mistakes women make is wearing the wrong bra size and it makes a huge difference on the run. Before buying your next high-impact sports bra for running, get properly measured or use a bra size calculator at home. Your size can change over time due to training, weight changes, or hormonal shifts so it’s worth double-checking every few months!

Pro tip: Look for brands that offer cup and band sizing (not just small/medium/large) for a more personalized fit.

2. Think Support, Not Just Style

Running is a high-impact activity, which means your sports bra should offer maximum support. Look for features like:

  • Encapsulation (separates and supports each breast individually)

  • Compression (holds everything close to your body)

  • Wide, adjustable straps

  • A snug, non-chafing band under the bust

A supportive running bra can reduce bounce by up to 74% and that means less pain, less distraction, and more focus on your running.

3. Test It With Movement (Not Just in the Mirror!)

We know trying on bras in-store (or even at home) can be awkward, but trust us do a few jumping jacks, arm swings, and high knees. A good sports bra for runners should stay in place, not ride up, and most importantly keep everything feeling secure.

If it shifts, pinches, or leaves marks after a few moves? It’s probably not the one.

4. Prioritise Breathable & Moisture-Wicking Fabrics

Running means sweat and lots of it. Choose a bra made from technical fabrics like nylon, polyester, or mesh panels that wick away moisture and help keep you cool and dry. Avoid cotton, which traps sweat and can cause chafing or irritation during longer runs.

Bonus points for anti-odor technology and quick-drying materials!

5. Pay Attention to Strap and Band Adjustability

Not all bodies are the same and that’s beautiful! Adjustable straps and back closures allow you to customise your fit. Racerback, crisscross, and U-back styles each offer different support levels, so try a few to see what feels best for your body type and running style.

Running bras with hook-and-eye closures tend to last longer too, since you can adjust the fit as the fabric naturally stretches over time.

6. Don’t Settle—Your Comfort Matters

Repeat after us: chafing is not normal. Neither is shoulder pain, red marks, or feeling like you can’t breathe. If your sports bra is uncomfortable in any way, it’s time to break up with it.

We believe every woman deserves to run without distraction. The right running bra should feel like a supportive teammate, not a tight cage.

Final Thoughts from the Collective

Finding the perfect running sports bra can take a little trial and error—but it’s so worth it. A well-fitting bra can improve your form, reduce breast pain, and even boost your confidence on the run.

So whether you're training for your next race or simply running for joy, don’t forget to support your girls. You’ve got miles to go and you deserve to feel amazing every step of the way.

Happy running!
