What this plan is built for
The Inca Trail asks for a stepped 1,250 m ascent to Dead Woman's Pass on day 2 and a 1,370 m stepped descent on day 3. The plan trains five things in parallel: the aerobic engine, vertical capacity, multi-day durability (the weekend pair), descent eccentric strength, and pack-carrying economy with your daypack, loaded as you will carry it (porters carry the camp). Altitude is the itinerary's job; the plan makes the walking cheap enough that altitude is the only hard thing. The stage-by-stage demand is on the Inca Trail trek page.
Before you start
- Base assumed: two or three sessions a week of any cardio for the last couple of months, and at least one day hike of 3 hours in the last year. From less, start the plan earlier and repeat the base phase.
- Hours: about 5.3 to 6.8 hours a week in the base phase, rising to about 12.4 in week 11, most of it on the weekend. With four or five hours a week, keep the Saturday walk and the Thursday vertical, drop the rest, and expect to need more weeks.
- Intensity: every walk and the Thursday session in Zone 2 (you can talk in sentences). The only hard session is Tuesday, from week 3. See how to find your zones.
- Terrain: stairs are the most specific training there is for this trek: a StairMaster, a stadium or a tall building, down as well as up.
- Pack: your daypack, loaded as you will carry it (porters carry the camp), on every long day from week 5.
The 16 weeks
Saturday is the long walk, Sunday the back-to-back day on tired legs, Thursday the midweek vertical (stairs, incline or hills), Friday eccentric strength, Tuesday one hard interval session from week 3, Monday an easy hour. The Saturday ascent peaks at 1,150 m, about 90 percent of the Inca Trail's biggest day, and the rehearsal in week 12 is the trek's biggest day in one go: about 8 hours, 1,150 m up and 1,350 m down, a scaled rehearsal of a day that is 8 to 10 hours and 1,370 m down on the trek itself; a rehearsal does not need the full dose.

Hours are time on your feet; gain is the vertical you go up in the session, and on the Sunday walk the descent matters as much as the ascent. Weeks 4, 8 and 13 are easy weeks on purpose, across the whole week: fitness is built in the recovery, not in the load (Banister et al., 1975). Tuesday from week 3: 6 x 3 minutes at Zone 4 with 2 minutes easy between (4 x 3 in the easy weeks), or hill repeats, 35 to 45 minutes in total. Monday: 60 minutes easy. Wednesday: rest or mobility.
The six phases
- Weeks 1 to 4, base. An easy hour on Monday, a Tuesday session (Zone 2 at first, intervals from week 3), a Thursday vertical session of 50 to 60 minutes (40 in the easy week), two short general strength sessions, and a Saturday walk growing from 2 to 3 hours. Week 4 is easy.
- Weeks 5 to 8, build. Add one eccentric strength session a week and make the weekend a pair: Saturday long, Sunday on tired legs. Week 8 is easy.
- Weeks 9 to 11, specific. Saturday grows to 5 hours and 1,150 m of gain, the Sunday walk stays long, midweek vertical peaks.
- Weeks 12 to 13, rehearsal. One 8 hour day with about 1,150 m up and 1,350 m down: steps up and a long stepped descent in the second half, the shape of day 3. The rest of week 12 is light, and week 13 recovers.
- Week 14, last big weekend. One more full pair, then the taper begins.
- Weeks 15 to 16, taper. Volume drops by about 48 percent in week 15 and 72 percent in week 16 against week 14, one short sharp session stays, legs arrive fresh.
The rehearsal week
Week 12 holds one day that mirrors the biggest day of the trek: steps up and a long stepped descent in the second half, the shape of day 3. It is not for fitness; it is for pacing, feet, fuelling and your head in the second half. The table places it four weeks before you go; with the real pack and the real food, and start before dawn if the trek's day does. The trek's biggest descent is 1,370 m in a day, so find as much descent as your terrain allows. The Sunday after it is a short easy walk, not a second long one, and the rest of that week is light.
Adapting the plan
- Coming from running or cycling: your engine is ahead; your legs are not. Keep the Saturday hours as written but start the eccentric strength in week 2, and do every long walk with the pack from week 3.
- Only weekends: keep the pair, move Thursday's vertical into Saturday's first hour, drop Tuesday. The plan still works; it just builds durability more slowly.
- A cold, a trip, a missed week: repeat the week you missed rather than skipping ahead. Two missed weeks in the specific phase mean a shorter rehearsal day, not a cancelled one.
- Knees that complain on descents: halve the Sunday distance for two weeks and double the eccentric session; legs that cannot brake are a common reason people struggle on the Inca Trail's descents.

Common questions
Is 16 weeks the right length for the Inca Trail?
The trek pages assume 12 to 16 weeks from a base of two or three sessions a week; this page is the 16-week version. If you already hike long days regularly, start at week 5 and you have the 12-week version. If you are starting from little, start earlier and repeat the base phase.
What if I only have four or five hours a week?
This plan does not fit in four hours at its peak. Keep the Saturday walk and the Thursday vertical, drop the Tuesday intervals and the Monday hour first, shorten the Sunday walk to an hour, and expect to need more weeks. The weekend pair is what builds consecutive-day durability; it is the last thing to cut.
I have no hills. Can I still follow it?
Yes. Stairs are the most specific training there is for this trek: a StairMaster, a stadium or a tall building, down as well as up. Count the vertical, not the kilometres.
What pack do I train with?
Your daypack, loaded as you will carry it (porters carry the camp), on every long day from week 5.
How is the personalised plan different from this page?
The app builds the same phases backwards from your departure date, sizes every session to your starting fitness and the hours you actually have, and rebuilds the next week every Sunday from what your watch recorded. This page is the fixed version; the app version bends when life does.
Can I train for the Inca Trail on a treadmill or StairMaster only?
For the engine and the vertical, yes: stairs are the most specific training there is for this trek: a StairMaster, a stadium or a tall building, down as well as up. Convert what the machine shows into metres of gain with the StairMaster calculator or the treadmill incline calculator and match the Thursday and Saturday gain in the table. What a machine cannot give you is rough ground, weather and the descent, so take the Sunday walk outside whenever you can, walk down as well as up when you do, and keep the Friday eccentric session; that is what makes the second week walkable.
Do I need to train for the Inca Trail at all?
Yes. The Inca Trail is 4 days in a row with about 6.2 hours and 450 m of ascent on a typical day and 8 to 10 hours on the longest, so the question is not whether you can walk one of those days but whether you can walk the last one. The plan trains that: consecutive long days, the daily vertical, descents and the pack. Starting from two or three sessions a week, 16 weeks is comfortable and 12 is the minimum; from nothing, start earlier and repeat the base phase.
Is there a printable or PDF version of this plan?
The table prints from your browser (print to PDF gives you the file), and the 16 rows plus the phase notes are the whole plan. There is no separate download because the fixed plan is only the starting point: the app version rebuilds the next week every Sunday from what your watch recorded, which a PDF cannot do.
