What this plan is built for
The Alta Via 1 asks for eleven stages rifugio to rifugio with your own 7 to 9 kg pack, short steep days of about 550 m of ascent and a 1,400 m descent to finish. 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 the full 7 to 9 kg hut-to-hut pack (no porters, no baggage transfer). Altitude is not the limiter here; accumulation, the daily ascent and the pack are. The stage-by-stage demand is on the Alta Via 1 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: hills with rocky, stepped paths if you have them, for the limestone ground; otherwise stairs or incline with the pack, and downhill repeats for the 7,200 m of descent.
- Pack: the full 7 to 9 kg hut-to-hut pack (no porters, no baggage transfer), 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 950 m, about 90 percent of the Alta Via 1's biggest day, and the rehearsal in week 12 is the trek's biggest day in one go: about 6 hours, 950 m up and 1,400 m down, a scaled rehearsal of a day that is 5.5 hours and 810 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 950 m of gain, the Sunday walk stays long, midweek vertical peaks.
- Weeks 12 to 13, rehearsal. One 6 hour day with about 950 m up and 1,400 m down: a 1,070 m ascent to a high hut and a long descent on limestone with the full pack, the ascent of stage 3 and the descent of stage 5 in one day. 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: a 1,070 m ascent to a high hut and a long descent on limestone with the full pack, the ascent of stage 3 and the descent of stage 5 in one day. 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 1,400 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 Alta Via 1's descents.

Common questions
Is 16 weeks the right length for the Alta Via 1?
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. Hills with rocky, stepped paths if you have them, for the limestone ground; otherwise stairs or incline with the pack, and downhill repeats for the 7,200 m of descent. Count the vertical, not the kilometres.
What pack do I train with?
The full 7 to 9 kg hut-to-hut pack (no porters, no baggage transfer), 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 Alta Via 1 on a treadmill or StairMaster only?
For the engine and the vertical, yes: hills with rocky, stepped paths if you have them, for the limestone ground; otherwise stairs or incline with the pack, and downhill repeats for the 7,200 m of descent. 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 Alta Via 1 at all?
Yes. The Alta Via 1 is 11 stages in a row with about 4.2 hours and 550 m of ascent on a typical day and 5.5 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.
