Tap a glass to log 250 ml. Today's target is 4.2 L — your 2.8 L baseline plus a heat adjustment for 31°C and this morning's 8K. Add 500 mg sodium per litre; your April sweat test came back high-sodium and plain water will dilute you.
Turn this on and the coach plans around your cycle rather than despite it. In the follicular phase you tolerate intensity better — that is where the quality sessions go. In the luteal phase core temperature runs 0.3–0.5°C hotter, so heat sessions cost more and aerobic volume earns more. Around menstruation, iron demand rises and the plan eases without you having to ask.
