Bottling — fill & mix

What it is. An athlete’s Setup describes the bottles and flasks they carry — their carriage — and how each one is filled and mixed. Saturday maps the per-hour prescription onto that carriage so the athlete knows exactly what to put in each bottle and when to drink it. That’s the whole journey: carriage → consumption. Open an athlete from your roster to see their carriage. When to turn it. When the athlete’s gear changes (more or fewer bottles, a bigger flask, a feed zone on course), when a too-concentrated mix is causing stomach trouble, or when what they carry doesn’t cover the session’s duration. Make the change from their Setup — open the athlete from your roster. What changes for the athlete. A concrete bottle plan — fill volumes, scoop counts, and a drink cadence — with none of the math left to them. They just drink the plan. The question it answers. “How much do I actually put in each bottle, and how often do I drink?”

What you do as a coach

  • Read it first. Open the athlete’s current carriage from your roster before changing anything — see ground truth, then adjust.
  • Adjust the count and concentration. Tap Adjust Setup to change how many bottles they carry and how concentrated each is. Saturday re-maps the consumption plan and shows a live impact sentence. (How the Setup works.)
  • Pre-fill for a new athlete. Setting up a less-techy athlete? From your roster, open them and dial in their bottling before they ever open the app — they arrive to a working plan (assisted onboarding).
Always “bottle.” Saturday says bottle — in the app, the portal, and these docs. Same word everywhere so nothing gets lost in translation with your athletes.

A full walkthrough is on the way: a 3-hour ride mapped across 2 bottles and a flask, concentration limits and how they relate to GI comfort, how a feed zone changes the plan, and how the app computes its live impact sentence. In the meantime, open an athlete from your roster and try it on a real carriage. Tracked in the coach nutrition curriculum sub-plan.
