Pace & mileage
How far can you walk in a day, and how to plan around it.
How far in a day?
Twenty miles a day is the thru-hiker's working number — but it's terrain that decides. Plan around the elevation profile, not the calendar.
Rule of thumb
flat 25–30 mi/day rolling 20 mi/day alpine 12–15 mi/day (passes, snow) town day whatever gets you to a bed
Why it matters
The biggest rookie mistake is a schedule that ignores the profile. A 22-mile day with a 4,000-foot pass is not the same walk as 22 flat miles.
