MILES OF MEANING / FIELD NOTES
Hydration: access, thirst and overdrinking
Plan access to fluid, but do not turn carrying capacity into a compulsory drinking target. More water and more salt are not automatically safer.

Evidence and interpretation
What the evidence says
Exercise-associated hyponatremia can occur when fluid intake exceeds the body’s ability to excrete it. Sodium-containing drinks do not prevent it when an athlete overdrinks. Recognition and treatment require medical judgment.
Editorial practice · not a validated protocol
Separate supply from consumption
For each segment, record the next confirmed water point, expected travel-time range and a backup if the point is unavailable. Use thirst as an important real-time cue; avoid forcing fluid simply to finish a bottle on schedule. Rehearse access and drinking in comparable conditions rather than copying another runner’s liters per hour.

Sodium and symptoms
A salty drink is not permission to exceed fluid needs. Do not self-diagnose sodium deficiency from cramps or fatigue alone. Confusion, collapse or serious deterioration during a race requires urgent assistance; taking extra water or salt is not a substitute for assessment.

Distance and environmental exposure
For 50K, one long remote segment can dominate the carrying plan. At 100 miles, check how supply and weather change after dark. For stages, confirm both course access and camp supply. A mountain course, heat or cold changes the planning context; there is no distance-only fluid equation.

Limits and practical takeaway
This is a safety and access guide, not an individualized fluid or electrolyte prescription. For unusual medical circumstances or very long exposure, agree a plan with a suitably qualified clinician or sports dietitian. Learn the event’s emergency procedure before starting.
