Triathlon Sports Bras – Built for the Swim, Ride, and Run

When your sport includes swimming, cycling and running—all in one go—you need a bra that can keep up with the entire race. Enter the triathlon sports bra—the ultimate multitasker. Whether you’re a seasoned competitor or training for your first sprint, the right bra for triathlon offers the support, comfort, and performance you need from start to finish. A good triathlon bra is all about smart design. It needs to be supportive enough to run in, comfortable enough to bike in, and water-ready for the swim—without slowing you down during transitions. Look for triathlon sports bras made with quick-dry, chlorine-resistant fabrics that won’t sag or chafe after the swim leg. Many also feature minimal seams, soft linings, and compression-style fits to reduce bounce and friction across all three disciplines. Fit and feel matter, especially over long distances. A quality triathlon bra should feel secure but breathable, with moisture-wicking fabric that keeps you dry through sweat, spray, and full-on downpours. Wide, supportive straps help distribute pressure evenly, and racerback or crossback styles allow a full range of motion for swimming strokes, aero bars, and running form. And while function leads the way, there’s no reason you can’t look great on race day. Today’s triathlon sports bras come in sleek, sporty designs with flattering fits and fun colours that pair perfectly with your tri suit or training gear. Many are stylish enough to wear solo during warm weather races or tough training days. So whether you’re tackling an Ironman or a weekend brick session, make sure your bra for triathlon is ready for the challenge. Because when you’re swimming, biking, and running back-to-back, you need a sports bra that performs as hard as you do—every step, stroke, and spin of the way.
