Print Story - Summit
design evolved from a conversation around "mountain logic" — how a runner forms the link between earth and sky through their ascent and descent of vertical terrain. Look for the ladder in the print, symbolizing that connection and transcendence.

Print Story - Spray Dye

The Spray Dye print capsule is inspired by the distinct differences of each waterway on this planet, and the greater interconnectivity they all share as a singular body.

Wash before first use on cold with like colors

Tumble dry low

Heads up — some color bleed may occur
Color bleed, especially with darker colored nylon/spandex blends, is common and could stain light colored garments if washed together.


Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

One of my favorite bras!

I have this bra in the Pacific color (past season) and it's easily a go-to for me. I love the quality and feel of the fabric as well as the unique style. It's so comfortable and stays in place regardless of the activity. I'm a 32C/D and the small fits great. I tried an XS but it was a little snugger than I like. I will definitely be buying more colors!

Perfect bra

Love this bra! I wear it for long runs, short runs and just to chill around the house. It hasn’t chafed me yet. Extremely comfy and cute.

Nina Leon
Favorite Running Sports Bra

No chafing and nothing moves or bounces. Pads aren't great but they do add coverage. Pretty design and very effective without feeling smooshed. Is a flatter look with this shaping but I always wear a shirt so it doesn't matter. Gorgeous color. Go to bra for running.

My lucky sports bra!

I absolutely love this sports bra! It is made of such comfortable and soft material and it provides the right amount of support. I love it so much, that it has become my lucky sports bra as I wear it for every hard track workout. The spray dye color is also so cute!

Best fitting sports bra EVAH

I've mostly splurged on Lulu sports bras, but hands down the Janji Groundwork Pace is far more supportive AND flattering. I feel like my measurements were taken - no smooshing from the sides in a one-size-fits all way... the underband is far more supportive and provides the stability and lift I've always expected but no other bra delivered. I also like the positioning of the straps - they are closer to your neck, so they don't need to constantly be adjusted back in place.

W's Groundwork Pace Sports Bra

Favorite bra

I now own three and just ordered the long bra as well. This bra has a barely-there feel, yet is perfectly compressive for my needs. No chafing (even in BRUTAL summer heat and humidity). I wear a small, find it runs true to size.

Cynthia Ramos
Fantastic support!

First of all the color is amazing! I got the Spray dye and I love it. The support is great. I’m 5’4” 120 lbs and wear a 32C and the small is a perfect fit. Very soft, love the shape and super sure straps. Very flattering.

Great bra and looks cute!

Great bra that has good support! Also looks really cute with a dress with a racer back!

Love Janjji Sports Bras

This is my 5th Janji bra and I love them. They fit well, but also are not impossible to get on and off when you're sticky and sweaty (there's enough stretch in straps I think) They are comfortable enough to wear all day at work so you don't have to change, or can change in the car, before heading out for a quick run. They look great alone, or under a tank top. The removeable inserts are new this year, and I personally didn't like them, but they are super easy to remove and the bra looks fine without them.
