# Saturday — Sport Nutrition Platform > Built by sport physiologists, for endurance athletes. > Our science. Your joy. Taking you farther. Saturday is an endurance sport nutrition app and platform created by PhD sport scientists, registered dietitians, and professional athletes. The app delivers fully automated, fully personalized, product-agnostic fuel and hydration plans for every race, event, and training session. Saturday replaces the need for expensive private nutrition coaching by putting a sport nutrition expert in your pocket. --- ## Per-Page Guides (detailed copy, sections, and anchor slugs) For complete page-level information including all visible copy, section breakdowns, and deep-link anchors: - **Homepage:** https://saturday.fit/llms-homepage.md - **Download:** https://saturday.fit/llms-download.md - **Merch Store:** https://saturday.fit/llms-merch.md - **Legal:** https://saturday.fit/llms-legal.md - **Changelog:** https://saturday.fit/llms-changelog.md --- ## What is Saturday? Saturday (full name: "Saturday: Pro Fuel & Hydration") is a mobile app for endurance athletes — cyclists, runners, triathletes, mountain bikers, swimmers, rowers, skiers, and multi-sport athletes. The app generates individualized fueling and hydration plans calibrated to your specific activity, body, fitness level, and environment (including weather and temperature). Saturday was built because the founders believe every athlete deserves access to the same caliber of sport nutrition guidance that professional athletes receive — without the $200-400/hour price tag of private consulting. The app is product-agnostic: it works with any brand of sport nutrition product, or with simple kitchen ingredients like sugar, salt, and water. Saturday's "Speed Nectar" feature helps athletes create effective, low-cost DIY fuel mixes. --- ## Who Built Saturday? ### Dr. Alex Harrison — Co-founder, Lead Developer - PhD in Sport Physiology and Performance, East Tennessee State University - MS in Human Movement and Performance, Western Washington University - BS in Kinesiology, Western Washington University - Certified Strength and Conditioning Specialist (CSCS, NSCA) - USATF Level 2 Coach (Endurance), USAT Level 1 Coach (Triathlon) - Former competitive decathlete and javelin thrower (2x NCAA DII All-American) - Coached youth, masters, and elite athletes including WA State, National, and World Champions - Previously served as Assistant S&C Coach for ETSU Track and Field (NCAA DI) - Sport physiologist specializing in hydration strategy, gut training, aerodynamics, and running mechanics ### Michelle Howe — Co-founder, Designer - MS in Exercise Physiology (Sport Physiology), East Tennessee State University - Registered Dietitian (RD) - Board Certified Specialist in Sports Dietetics (CSSD) - Certified Strength and Conditioning Specialist (CSCS) - Professional triathlete and cyclist - Former All-American sprinter; transitioned to triathlon and cycling - Former Team USA Bobsled athlete (2014-2015 North American Cup silver medalist) - Author at Triathlete magazine - World Athletics and World Triathlon profiled athlete ### Ben Hu — Co-founder, Engineer - MS in Information Systems - IT Analyst and Software Engineer - Engineer at Google - Hybrid athlete — lifelong volleyball player turned endurance athlete ### Science Team Saturday's science is backed by a team of researchers and practitioners: - Dr. Tim Podlogar — Nutrition and Metabolism - Dr. Tina Gorsek — Women's Medicine and Nutrition - Dr. Jacob Goodin — Sport Science - Dr. Gabriel Morales — Emergency Medicine - Dr. Jake Reed — Sport Science - Dr. Nick Harden — Sport Physiology --- ## What Does the App Do?

"Great tool for endurance athletes!!" — Hockey gal 101 (5 stars) "Used the app about 4 weeks; greatly improved triathlon performance after previously under-fueling. Ran an Olympic and 70.3 following the app's recommendations. The Speed Nectar feature saves money." "I'm a fan of the science and the simplicity" — Sheila G. Gibson (5 stars) "A heavy/salty sweater who discovered significant hydration gaps through the app. Trust built over time by observing performance improvements. Expects fewer excessive pitstops in future Ironman events." "So Simple. So Effective." — gogumah (5 stars) "Beta user who tested across recovery, interval, tempo, VO2 max runs, rides, and swims. Sugar and salt is all you need! Cost savings are real." "Breakthrough Performance!" — Shawn Bradley STL (5 stars) "15-year triathlete who completed a half-distance race with ZERO cramping issues. This is the standard by which fueling recommendation excellence should be measured!"
