Lululemon’s Further initiative, which took place at Lake Cahuilla in La Quinta, California, in March 2024, was basically a lab study with 10 women running a 2.55-mile course for six days—144 hours. The participants ranged in experience levels and included world record holder and ultrarunner Camille Herron, ultrarunner and author Mirna Valerio, and ultrarunner Devon Yanko, among others. Collectively, the 10 women ran over 2,000 miles. They were fitted with 36 pieces of bespoke gear created through 3D body scans.

This year, finally, Lululemon is slowly unveiling a race kit the rest of us can wear, and it starts with the Go Further Bra.

The Go Further Bra is a summation of the product team’s research surrounding the six-day event. The team began by asking the athletes what were their unmet sports bra needs.

“A lot of it came down to the notion that the smallest little thing can become a large problem over many, many days,” said Chantelle Murnaghan, Lululemon’s vice president of research and product innovation. “High support is non-negotiable for these athletes who have a broad range of sizes in terms of breast volume. We needed to accommodate that and then think about what are all of the other things that we can consider: a beautiful hand-feel material with soft edges, how design lines are placed on particular areas of the body, how we add slight padding on the straps and the underband.”

There are usually two modes of support runners can choose from when it comes to sports bras: compression or encapsulation. Compression is when a sports bra literally compresses the breasts to stop them from bouncing. Encapsulation is when a sports bra has two separate cups to support each breast individually. But the Go Further Bra introduces a different kind of sports bra support tech: Lululemon’s Support Code.

“Support code technology is a bonding technique that changes the modulus of the fabric, so you can think of it as changing the stiffness and targeting support,” explained Murnaghan. “If you have an encapsulated bra, you have a very structured foam cup so that when it sits flat, it really has this like perfectly rounded. With this bra, it’s a completely different way of achieving that movement management where we maintain the natural shape of the breast because we have a molded panel, but there’s no foam cup that keeps it really rigid and stiff.”

You can visually see Support Code when you lay the Go Further Bra flat on a table. The cups will pucker up instead of lying flat like on a compression bra. The cups are also sunken, unlike the twin conical domes you’d see on an encapsulation bra.

When senior features editor Pavlína Černá initially saw the Go Further Bra lying on her desk, she had doubts that the bra would fit. Though it was her usual size (small) she was convinced the cups looked too large for her frame (Černá wears a B cup).

“Dude, that bra is S? They are crazy,” she messaged me.

The next day, however, she changed her mind. “I take back everything I said about the bra. It fits perfectly.”

After several test runs in the Go Further, Černá was obsessed.

“I have worn the bra for all the runs I could ever since I got her,” Černá wrote on her feedback form. “She is my new favorite. If I were ever forced to choose just one of my bras to run in for the rest of my running life, she would be it.

“From the look of her, I was convinced that she would never fit, and that she’s made for much bigger boobs than mine (32B). And was I wrong! She fits like a glove and is easy to put on and take off. She doesn’t deprive me of air but is completely supportive on my runs.”

The Go Further’s material—Lululemon’s trademarked Ultralu fabric—feels smooth and buttery. A seamless construction molds to your body, while padded straps prevent annoying indentations from appearing on your shoulders. The material is light and breathable, but a keyhole on the crossback design provides even more airflow.

A couple things to note before running in the Go Further is that it comes in alpha sizing, meaning, instead of cup/band, it’s sized from XXS to XL. The baseline cup size is C/D. It’s free of hook-and-eyes and adjustable straps because the Lululemon team wanted a high-intensity bra with a minimalistic design.

“We really wanted to lean into the opportunity with this bra to create an amazing complement to [our bra] assortment,” said Murnaghan, naming off Lululemon’s adjustable Run Times Sports Bra and medium-impact Energy Bra as other support choices. “[It’s] really rare to get a high-support bra that has that pull-on, pull-off in a minimalist experience on-body.”

According Murnaghan, the main features Further athletes wanted were comfort, lightweight, and minimalist. As a simple pullover with Support Code, the Go Further checks off all three. Our testing showed the Go Further is comfy and truly inclusive with its design.

“I was so nervous about this bra when I got it because there was no way to adjust it, but I ended up really liking it!” said Aly Ellis, RW’s director of hype, who wears a size D cup and tested a size large. “There was minimal bounce, which is hard to come by for me. There was no rubbing or chafing. Overall, a solid running bra for larger chested women!”
