Altitude Gain Guidelines

Daily Ascent Guidelines

700m

Exceeds Guidelines (>500m)

Current Sleeping Altitude (m)2500

Planned Sleeping Altitude (m)3200

Climb High, Sleep Low: Above 3000m, increase sleeping altitude by at most 300–500m per day. Plan a rest day (stay at same altitude) every 3–4 days or every 1000m gained.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Pre-participation screening for athletes planning high-altitude training camps or competitions above 2500 m.

Risk stratification for acute mountain sickness (AMS), high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE) in endurance athletes.

Guiding gradual ascent protocols for trekkers, climbers, and skiers to prevent altitude illness.

Monitoring acclimatization status in athletes during multi-day altitude sojourns.

Post-altitude exposure assessment to determine safe return to sea-level training.

Key Indication - Altitude Illness Risk Stratification

The Altitude Gain Guidelines are primarily used to stratify risk of altitude illness based on rate of ascent, absolute altitude reached, and individual susceptibility. According to the Wilderness Medical Society (WMS) and ACSM guidelines, a daily altitude gain exceeding 300-500 m above 3000 m significantly increases AMS risk. The tool integrates the Lake Louise Scoring System for AMS diagnosis and provides ascent rate recommendations to minimize HAPE/HACE incidence.

When Not to Use / Contraindications

Do not use as a substitute for immediate medical evacuation in severe AMS, HAPE, or HACE.

Not applicable for individuals with pre-existing severe cardiopulmonary disease (e.g., pulmonary hypertension, unstable angina) without specialist clearance.

Invalid for predicting altitude illness in rapid ascent by helicopter or vehicle (e.g., >1000 m/day).

Not reliable for children under 12 years or pregnant women due to limited validation.

Do not use for acute assessment of hypobaric hypoxia in unacclimatized individuals without baseline oxygen saturation measurement.
