The Altitude Advantage: Nutrition at Elevation for Colorado Athletes
A comprehensive guide to how altitude from 5,000-7,100+ feet changes iron needs, hydration demands, carbohydrate metabolism, and fueling strategy for XC and track distance runners.
Why this matters
If you coach in Colorado, Utah, Arizona, or New Mexico, you coach at altitude.

Hydration
Start drinking sooner than you think
- Cool dry air hides losses, so many athletes arrive under-hydrated without realizing it.
- Water plus electrolytes helps more when training load and altitude stack together.
Fueling
Use carbohydrate well to support harder breathing and harder work
- Altitude training and racing often feel better with cleaner carb support around sessions.
- Bagels, rice, oats, fruit, sports drinks, and simple snacks are practical tools.
Iron
Do not ignore low stores in athletes already at risk
- Distance runners, menstruating athletes, and anyone with prior low ferritin need closer attention.
- Food-first iron support is helpful, but labs and clinician guidance often matter more.
Iron: The Most Critical Altitude Nutrition Variable
Red blood cell production requires iron.
Red blood cell production requires iron. Specifically, the hemoglobin molecule in each red blood cell contains iron as its functional core — it's the iron that binds and carries oxygen. You cannot make red blood cells without it.
At altitude, the body's demand for iron increases because it is attempting to produce more red blood cells than it would at sea level. Altitude magnifies iron deficiency. An athlete who might function adequately at sea level with borderline iron stores will see meaningful performance impairment at 5,000–6,000 feet…
Why Altitude Is Different: The Physiology in Plain Language
At altitude, the air is thinner.
Increasing respiration rate — breathing faster and more deeply to compensate
Increasing red blood cell production over weeks to months — more red blood cells carry more oxygen…
Elevating heart rate at any given pace — the cardiovascular system works harder to deliver…
Upregulating erythropoietin (EPO) — the hormone that stimulates red blood cell production
