Saturday makes elite endurance nutrition accessible and easy so you can be confident and relaxed on race day.

Save your pain tolerance for your big event.

Saturday is designed to deliver the best training session of your life, or your money back.

Gone are the days of shelling out hundreds on hydration products that are just wild guesses or some corporate-influenced industry "standard."

When has anyone wanted to be called "standard" anyway.

You deserve better.

Better science.

Better individualization.

Optimized fuel & hydration tailored to you, your training, and your environment, Saturday will revolutionize your endurance experience.

You deserve more.

More thoughtfulness.

More paying attention to details, so you don't have to.

No more paying premium prices for private nutrition coaching, just to have confidence in your fuel & hydration plan.

We should all be able to fuel the sports we love.

make.
fuel.
simple.

Have you ever wondered why companies like Maurten, Skratch, Science in Sport, or Untapped charge such high prices for their products? The answer: because they can. The whole industry is designed to confuse you into believing that the only way to have a great race is to eat and drink expensive gels, chews and fancy packaged powders. Say no to fancy sachets and packets. Say yes to easier customization, saving money, saving time, better performance, and more confidence in your fuel and hydration on race day.

Say yes to better training, less fear, less waste, and less marketing hogwash.

Saturday teaches you exactly how to fuel, how to hydrate and what products you need, and how much. From salt, sodium chloride, sodium citrate, sugar, maltodextrin, fructose, you name it, Saturday has you covered and considers it all.

In our hand-curated product list only contains products that can be made to work in your scientifically backed fuel plan. They have the right amounts of carbs, protein, fiber, fat, and sodium to work into the plans that we write for you. If they don't have the right amounts of those things, they don't make our list because we wouldn't recommend them to you. Gut issues are too important to avoid and the details matter.

You can track your progress towards your nutrition goals by looking back at your ratings about how training went, and how your fuel affected you with our note-taking feature and activity rating features.

Welcome to the future of fuel.

Works awesome. I'm not ready to completely ditch my purchased fuel, but this app does zero in on what's missing (hint, it's sodium) using that app as my guide I've managed to avoid cramping that has plagued me for a while. Ends up I just needed a little more sodium. The app helps get that dialed in for each day based on me, the activity, length and the weather. It's going to be a key factor in my success at Unbound.

Saturday has saved me a huge amount of time preparing for my long runs. I used to math out strategies for fueling. Now, I have an app that does that for me! The app is easy to use and has most of my favorite fule pre loaded. Custom items are quick to add. All you need is carbs and sodium amounts per serving. I recommend it to anyone in the endurance sports community!

This has been a game-changer for me. It makes it easy for me to know how much fuel to use for easy run or an intense workout or anything in between. Super simple, and I can also use their recommendations to make my own "Speed Nectar", which has saved me a TON of money!! And, one of the best parts is that it not only tells me how much sugar I need, but also how much sodium!! Highly recommend this app to help anyone, from the beginner to the advanced athlete.

We're so glad you found the app simple to use!! Of course, we pride ourselves on being scientific, but we like to think the thing that makes this app special is how focused it is on making it easy for folks. Simple, but not simple-minded. :) If you ever need anything, email us! support@saturdaymorning.fit
