Personal fuelling for training and race day, from how you sweat, the weather and the products you use. By a US board-certified sports dietitian and a PhD sport scientist. Saturday is personal fueling for runners, cyclists and triathletes, built by a board-certified sports dietitian and a PhD sport scientist, both former Team USA athletes. Tell it about your training session or race, and it plans what to drink and eat each hour from how much you sweat and the weather, then turns that plan into drinks you mix yourself or the gels and drink mixes you use. "Saturday has been incredible both with taking the guess work out of fueling and improving my workouts... definitely recommend!" - Dan Laurich, Triathlete "My half marathon was AMAZING! 7-minute PR! The fuel was great. Everything just clicked. Big confidence boost. I feel ready to get back to my training tomorrow. I’m happy!" - Kasie P., Runner "If you want to get out of the black box of mid ride/race nutrition needs, Saturday is the app for you!" - Skip Kastroll - XC & Enduro MTB racer "I’ve trusted Saturday for everything. From hot laps with the guys to ultra endurance gravel races." - Tarah Romano, Cyclist "I hate training without it." - Michelle Howe, professional triathlete Saturday makes elite endurance nutrition accessible and easy so you can be confident and relaxed in training and on race day. Saturday is designed to deliver the best training session of your life. Gone are the days of shelling out hundreds on hydration products that are just wild guesses or some corporate-influenced industry "standard." You deserve better. Better science. Better individualization. Optimized fuel & hydration tailored to you, your training, and your environment, Saturday will revolutionize your endurance experience. 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. Our science. Your joy. Taking you farther. End User License Agreement (EULA): https://saturday.fit/app-terms Privacy policy: https://saturday.fit/app-privacy
