Altitude Itinerary Check
Enter the elevation of each night on a high-altitude trek and this checks the schedule against the published sleeping-gain and rest-day guidance. It checks the plan only.
Check the sleeping elevations
Enter the elevation of each night in order. This checks the schedule against published planning guidance. It cannot assess a person, and it never will.
What you get back
- A profile of your sleeping elevations, with any step over the guidance marked.
- Whether the rest days match the total gain, and where a missing one belongs.
- The symptom and descent rules, which are shown on every result and override any schedule.
The arithmetic is simple and easy to get wrong by hand, which is the only reason this exists.
- Sleeping gain above 10,000 ft
- About 1,650 ft or less per day
- Total gain
- An extra day for each 3,300 ft, placed before the highest exposure
- First night
- Keep it as low as practical
- First 48 hours
- Light effort, no alcohol
- Symptoms
- Do not sleep higher
- Emergency signs
- Descent cannot wait
Thresholds are published in feet, so metric entries are converted and judged against the same numbers. The metre figures shown back to you are labels, not separate rules.
What this deliberately refuses to do
It never asks how you feel, and it never will.
A tool that collects symptoms and returns a verdict invites somebody to keep walking because a page said the number looked acceptable. So this one has no symptom input, no score, and no way to output the word safe.
The symptom and emergency rules sit at the top of every result, including results where the schedule clears every rule. A clean plan does not cancel a red flag, and the warning signs outrank any itinerary.
A schedule that passes is a schedule with no conflicts in it. It is not a prediction about you.
