User reviews

Not just for elite athletes!

I discovered Saturday’s reviews on YouTube and found them knowledgeable, factual and entertaining. Plus, I have learned SO MUCH about fueling and hydration. So, I decided to give the app a try. I’m a non-competitive runner with 10ks and Halfs my primary races, and I have found this app invaluable when it’s time to prepare my hydration and fuel for my training runs. It isn’t just for elite athletes. Are there things that could be improved or functionalities that could be added? Yes. But given this is more of a home-grown app AND it’s relatively inexpensive, I am more than willing to overlook those missing “nice to haves.”

Great app!

Works well. Fits into my workouts seamlessly.

Amazing App

This is the best fueling investment I’ve ever made, and I don’t know what took me so long to write this review. Saturday takes the guesswork out of having the right amount of fuel for a ride. The support provided for any issues you may encounter is second to none. I can’t recommend this product enough to anyone struggling (or not) with proper fueling.

Great App!

I love this app. It works well and is clean and simple. I bet it has already saved me a hundred dollars just in one training block and race by not buying gels.

I have used it for ultramarathon training and race day execution. It has really helped solve the nutrition puzzle for me. I used to get cramps and lag in energy at later stages. But for my last race when I followed the advice from the app, I felt great the entire race and didn’t have any cramps.

Easy way to calculate fueling

I use it for every long workout and it’s a super easy way to know how much I need to take in during a ride. My recovery has improved a ton since using this and I am much better able to make endurance gains off of my long rides since I am hydrated and fueled properly.
