Our story

Built by athletes who want to keep doing what they love, for years to come.

RNWY started with a simple question: what's actually in your fuel, how much, and why? We built RNWY to answer that: Formulas that do what they say, made for the long game.

Our Story

Where it started

We wanted to take the right things. Not just before a race, but for a lifetime of training.

RNWY started with a question we couldn't shake: what would it actually take to keep running, riding, and training for decades…not just to survive this season, but to still be doing this at 60? The answer wasn't another combination of random supplements. It was joints, tendons, and hydration that could keep up with the miles. That became Foundation®.

Once Foundation® was right, dosed at levels the research actually supports, with nothing hidden in a blend, the rest of the system followed. Extra Mile®, Salty Carbs®, and Complete Protein were built to cover the rest of an athlete's day without ever duplicating what was already there. What started as one product built for the long game became four, built the same way.

What we knew had to be true


Every dose disclosed

No proprietary blends. If an ingredient is on the label, the amount is too.


Doses that match the research

If we can't include something at the level studies say works, we leave it out entirely.


A system, not a shelf of random products

Four products built together so nothing overlaps and nothing is missing.


Third-party tested, not just claimed

Informed Sport certification on every product. Every batch checked by an independent lab.

What RNWY stands for

Four principles that shape every formula, label, and decision we make.*

Transparency over hype

Every ingredient, every dose, every certification listed so you can verify it yourself, not just take our word for it.

Built for the long game

Not race-day hacks. Products designed for athletes training week after week, season after season, for years.

A system, designed together

Four products formulated as one system from day one, so stacking them never means duplicating ingredients.

Tested, not trusted blindly

Informed Sport certified across the line. Every batch screened by an independent lab before it reaches you.

Who this is for

If you've ever read a supplement label and thought "what does that actually mean” RNWY is for you.

We built RNWY for runners, cyclists, triathletes, and anyone else who trains consistently and wants their nutrition to be as deliberate as their training plan.*

You don't have to be elite. You just have to care about what you're putting in your body and want a straight answer about why it's there.*

🏃

Marathon & ultra runners

Logging high mileage week after week and need fueling and recovery that actually keeps pace.

🚴

Cyclists & triathletes

Managing long sessions across disciplines, where every product needs to earn its place in the bag.

🔍

Label readers

Athletes who check ingredient lists, look up doses, and want their supplements to hold up to scrutiny.*

🌱

Anyone playing the long game

Training for years, not just a single season… and building habits that actually hold up over time.

About RNWY

What does RNWY make? +

RNWY makes four performance nutrition products designed as one system for endurance athletes: Extra Mile® (caffeine-free pre-workout), Salty Carbs® (dual-pathway intra-workout fuel), Complete Protein (fermented yeast protein with creatine), and Foundation® (daily collagen and electrolyte support). Each product covers a distinct part of an athlete's day with no overlapping ingredients.

Where are RNWY products made? +

Manufactured in the USA.

Is RNWY a real, independently-tested brand? +

Yes. Every RNWY product is Informed Sport certified, meaning every production batch is tested by an independent lab for substances banned in competitive sport, not just a one-time formula review. Full ingredient breakdowns for every product are available on our Science page.

Why doesn't RNWY use proprietary blends? +

Proprietary blends list a combined weight for a group of ingredients without disclosing how much of each is included. Because most active ingredients have a minimum effective dose established in research, this makes it impossible to know whether a product can actually do what it claims. RNWY lists every active ingredient individually with its exact amount, dosed to match the research behind it.*

How do I get started with RNWY? +

The Daily Essentials Bundle (Foundation® + Complete Protein) is the simplest starting point. Two products covering daily joint support and post-workout recovery. Athletes who train more than a few hours a week often move to the full Performance Stack, which adds Extra Mile® and Salty Carbs® and makes for one easy order.
