The Appalachian Trail Conservancy says most thru-hikes take five to seven months. This is a broad planning range, not a completion promise.
Count non-walking time
The Conservancy's FAQ provides timing context. Your plan also needs rest, resupply, weather flexibility and changes in pace. A mileage calculation alone leaves out much of the journey.
Learn from shorter trips
Try manageable multi-day walking and record time spent packing and arranging supplies. Observe recovery as well as daily distance. Those details help assess whether an extended trip fits your budget and available time.
Apply realistic timing to Atlas trips
Short holidays still include transfers and overnight logistics. Use the Atlas three-day planning guide before counting each calendar day as a full walking day. A realistic schedule is more valuable than an ambitious average speed.
