Why the Salkantay Trek catches fit people out
The Salkantay Trek is mostly good mule track with no scrambling, a camp crew, a hot meal every night and Machu Picchu at the end. No permit, open all year. That is the trap. People choose it because the Inca Trail is sold out, train for the Inca Trail they read about, and arrive at a trek that is longer (79 km against 45), goes higher (4,630 m against 4,215) and descends far more (4,925 m against 2,460), carrying a 5 to 8 kg daypack.
Three things do the damage. The first is the pass day: day 2 (Soraypampa to Chaullay) is 22 km and 8 to 11 hours, 810 m up steep rocky zigzags to the Salkantay Pass at 4,630 m, where snow is possible, then 1,810 m down to a camp at 2,900 m, on the second day of the trek. The second is the descent that never stops: days 2, 3 and 4 each drop more than 1,000 m (1,810, 1,275 and 1,193 m), 4,925 m in five days. The third is day 4, the one the brochures undersell: 24.2 km and 8 to 9 hours, with the biggest ascent of the trek, 1,291 m up a steep forest path to Llactapata, then 1,193 m down to Hidroelectrica and the rail-side walk to Aguas Calientes, on legs that have already done the pass and the valley.
The stage profile: the classic 5-day Salkantay Trek, Challacancha to Machu Picchu, day by day
Training for a trek starts with its shape. The table is the classic 5-day itinerary from Challacancha, the road end above Mollepata where most operators now start, with the Humantay Lake side trip on day 1 and the Llactapata crossing on day 4: what the plan is built from, and what you can check your own operator's version against. The 4-day version keeps days 1 and 2, drops Llactapata for a vehicle down the valley to Hidroelectrica and reaches Machu Picchu on day 4; the older start from Mollepata adds a long first day before Soraypampa.
| Day | Stage | km | Gain m | Loss m | Hours | Sleep at |
|---|---|---|---|---|---|---|
| 1 | Challacancha (3,800 m) to Soraypampa, with the Humantay Lake side trip (4,200 m) | 10 | +670 | -550 | 5 to 6 | 3,900 m |
| 2 | Soraypampa to Chaullay via the Salkantay Pass (4,630 m) | 22 | +810 | -1,810 | 8 to 11 | 2,900 m |
| 3 | Chaullay to Lucmabamba | 18.9 | +470 | -1,275 | 5 to 6 | 2,060 m |
| 4 | Lucmabamba to Aguas Calientes via Llactapata (2,800 m) and Hidroelectrica | 24.2 | +1,291 | -1,193 | 8 to 9 | 2,040 m |
| 5 | Aguas Calientes to Machu Picchu (2,430 m) | 3.5 | +466 | -97 | 1 to 4 | trek ends |
About 79 km, 3,707 m of ascent and 4,925 m of descent over five days. Three nights in camps (tents, huts or domes depending on the operator), the highest at Soraypampa, 3,900 m, and the last night in a hotel at Aguas Calientes. Mules carry the camp and the duffel; you carry a 5 to 8 kg daypack. Day 5 needs a timed, name-specific Machu Picchu ticket. Daily figures differ by operator and by camp choice; the table follows the canonical trek database (two independent itineraries plus a terrain measurement of the route, checked 2026-10-18).
Read the table as a training brief. Day 1 is the warm-up with a sting: 10 km and 670 m of gain including the side trip up to Humantay Lake (the day's high point, 4,200 m), then the highest night of the trek at 3,900 m. Day 2 is the trek: 810 m up to the pass, 1,810 m down, 22 km, 8 to 11 hours. Day 3 keeps descending, 1,275 m over 18.9 km into the cloud forest. Day 4 is the long second act: 1,291 m up over Llactapata and 1,193 m down, 24.2 km, 8 to 9 hours. Day 5 is the walk up to Machu Picchu, 466 m on steps, before the ticket time. The early pass, the stacked descents and the big day 4 ascent on tired legs are what the plan is built around.
What a trek asks that a summit does not
Kilimanjaro has one summit night and a walk out. The Salkantay Trek puts its pass on day two, then descends for three days in a row with its biggest ascent in the middle of them. That is a different physiology, and a plan built for a single big day misses it.
- Consecutive long days, not one. Four days in a row over five hours, two of them over eight, and no rest day. Fatigue accumulates faster than fitness recovers, so the plan trains back-to-back long days, not a single rehearsal.
- The hardest day comes second. Day 2 is 8 to 11 hours with 810 m up and 1,810 m down, after one night at 3,900 m. The rehearsal day in training mimics that order: a long ascent, then a longer descent, with the real pack.
- Descent is the trek. 4,925 m of descent in five days, three days over 1,000 m, the biggest off the pass on loose, rocky ground. Eccentric leg strength is not an add-on; it is what gets you to Aguas Calientes walking rather than limping.
- The big ascent arrives tired. The biggest ascent of the trek, 1,291 m up a steep forest path to Llactapata, is on day 4, not day 1. The Saturday long day in the plan is sized to it, and it is done on legs that already walked on Friday.
- A daypack, not a load. Mules carry the camp and the duffel, and a crew cooks. You carry 5 to 8 kg of water, layers and rain gear, and shops and lunch stops exist along the valley. Train with that pack, loaded as you will carry it.
Physical benchmarks to hit before the Salkantay Trek
The Salkantay Trek loads five physiological systems. A real preparation plan trains all five, with the descent and the consecutive long days at the centre.
Altitude: what the itinerary handles and what training cannot
Training builds the engine. Altitude is its own thing. The Salkantay Pass at 4,630 m (15,190 ft) holds a little under 60 percent of sea-level oxygen, and the trek reaches it on day 2, which is too soon for the trek itself to acclimatise you. What does the work is the two or three days operators tell you to spend in Cusco first. Keep them. The nights on the trek are at 3,900, 2,900, 2,060 and 2,040 m: only Soraypampa, the first night, is above 3,000 m, and snow and freezing temperatures are possible there and on the pass even in the dry season. Walking the pass slowly is what keeps day 2 a long day rather than a sick one.
From Chaullay onward the trek is below 3,000 m and altitude stops being the limiter. What replaces it is descent, distance and weather: three days over 1,000 m of descent, an 8 to 9 hour day over Llactapata, rain and mud from about November to March, and a valley road that landslides can close in the wet season. The fitter you are, the lower the effort of each hour and the more reserve you keep for the pass and for day 4. Our altitude acclimatisation guide covers the per-night ascent ceiling and AMS warning signs, and the acclimatisation training guide covers what pre-acclimatisation can and cannot do.
The 12 to 16 week Salkantay Trek preparation timeline
The block runs backwards from your departure date. Six phases, each with a distinct target. The hardest training weeks land three to six weeks before you fly, not in the final taper.
- Weeks 1 to 4 · Aerobic base. Three to four Z2 sessions a week, 45 to 90 minutes. Walk, hike, run, cycle; weight on feet preferred.
- Weeks 5 to 8 · Base plus strength plus the weekend pair. Add one eccentric leg session a week and make the weekend two consecutive Z2 hikes, the second one descent-heavy, pack on.
- Weeks 9 to 11 · Muscular endurance. Weekend days grow to 4 to 5 hours with 1,000 to 1,300 m of gain (day 4 is 1,291 m), the Sunday walk stays long and downhill. Stairs and incline if you have no hills.
- Weeks 12 to 13 · Pass-day rehearsal. One 8 to 11 hour day with about 810 m up and a descent longer than the ascent, the real pack and the real food: the shape of day 2.
- Week 14 · Last big weekend. One more back-to-back pair at full length, then the taper begins.
- Weeks 15 to 16 · Taper. Volume drops 30 to 50 percent, one short sharp session stays, legs arrive fresh in Cusco for the acclimatisation days.
A weekly distribution that works
The polarised principle applies: most of the week at low intensity, one hard session, and the weekend pair that makes a trek plan different from a summit plan, two long days back to back (Seiler & Kjerland, 2006). A representative week, 10 weeks out from Salkantay Trek:
- Mon · easy 60 min Z2 walk or run
- Tue · threshold intervals, 4 x 4 min Z4, or hill repeats
- Wed · rest or 30 min mobility
- Thu · 60 to 90 min stairs or treadmill incline, Z2, 5 to 8 kg daypack on, 400 to 600 m of gain, down as well as up
- Fri · eccentric strength: weighted step-downs, split squats, calf and hip work, 40 min
- Sat · long Z2 hike, 4 to 5 hours, 1,000 to 1,300 m of gain, full daypack
- Sun · second long walk on tired legs, 2.5 to 3.5 hours, descent-heavy, pack on (the back-to-back day)
Roughly 80% of weekly volume sits at Z1 to Z2, with one hard intensity session and the back-to-back weekend. Vertical and hours accumulate progressively across the block. The deeper rationale is in our heart rate zones guide; the descent work is explained in eccentric descent training.
How TTM trains the plan to the Salkantay Trek
Five things the plan is built around
- Fitness target · The Salkantay Trek is set to a fitness target the model associates with walking the five days with margin. Your plan is engineered to reach that level by your departure date, and the readiness number tells you how far off you are, with the basis stated.
- Stage-shaped long days · The weekend long days are sized from the itinerary above, not from a generic hiking template: Saturday grows toward the 1,291 m ascent of day 4, Sunday toward the 1,810 m descent of day 2.
- Back-to-back loading · The plan schedules consecutive long days in the build and specific phases because that is the demand. Multi-day durability is scored as its own component of your readiness.
- Descent eccentric load · Eccentric strength and downhill repeats are programmed from the middle of the plan to prepare for 4,925 m of descent in five days, not bolted on at the end.
- Weekly recalibration · Every Sunday the plan re-reads your watch data (Garmin, Suunto, Coros, Polar, Apple Health) and adjusts the next week: missed sessions, a cold, a bigger-than-planned weekend, all accounted for.
When you tell TTM your trek is the Salkantay Trek and your departure date, the plan is built backwards from that date with the stage profile above engineered in, and it recalculates every week, every Sunday, against your actual training data from your watch. You do not need to assemble the pieces yourself.
Salkantay Trek: quick answers
How fit do I need to be for the Salkantay Trek?
Fit enough to walk about 5.5 hours a day for 5 days with a 5 to 8 kg daypack, including an 8 to 11 hour pass day with 810 m up and 1,810 m down on day 2 and an 8 to 9 hour day with 1,291 m of ascent on day 4. No technical skill is needed. The benchmark that matters most is the pair: a long ascent on Saturday and a long descent on Sunday that leave your knees fine on Monday. If one long downhill wrecks you for three days, you have a durability gap, and that is what 12 to 16 weeks of training fixes.
How many weeks does it take to train for the Salkantay Trek?
Twelve to sixteen weeks from a base of two or three sessions a week. Less if you already hike long days with big descents regularly; more if you are starting from little. The hardest training weeks should land three to six weeks before you fly, with a two week taper after them.
What is the hardest day of the Salkantay Trek?
Day 2, Soraypampa to Chaullay over the Salkantay Pass: 22 km, 810 m up steep rocky zigzags to 4,630 m, then 1,810 m down, 8 to 11 hours, on the second day. Day 4 is the one people do not expect: 24.2 km and 8 to 9 hours with the biggest ascent of the trek, 1,291 m up to Llactapata, then 1,193 m down to Hidroelectrica and on to Aguas Calientes.
Is the Salkantay Trek harder than the Inca Trail?
By the numbers, yes. The Salkantay Trek is 79 km in 5 days against 45 km in 4 for the Inca Trail, its pass is 4,630 m against 4,215, and it descends 4,925 m against 2,460. Its pass day alone is 8 to 11 hours. The Inca Trail has more stone steps; the Salkantay Trek has more hours, more descent and a bigger ascent on day 4. It has no permit quota and stays open all year.
Can I train for the Salkantay Trek altitude at sea level?
You cannot acclimatise at sea level. The pass is 4,630 m on day 2, so the acclimatisation happens in Cusco before the trek: keep the two or three days operators schedule there. After the pass the trek drops below 3,000 m for good. What training does is lower the cost of each hour so you keep reserve for the pass.
Do I need to train with a weighted pack for the Salkantay Trek?
Yes, with the pack you will actually carry: a 5 to 8 kg daypack of water, layers and rain gear while mules carry the camp and the duffel (duffel limits vary by operator). Carry your real pack on every long training day so shoulders, hips and stride are used to it.
Do I need a permit for the Salkantay Trek, and when should I go?
No trek permit and no quota, which is why it sells when the Inca Trail does not; there is a small local entry fee for Humantay Lake and the route, and day 5 needs a timed, name-specific Machu Picchu ticket, so book that first. The route stays open all year. The dry season is May to September; rain and mud are most likely from about November to March, and operators advise waterproof trousers from September to March. Plan the 12 to 16 week block backwards from the Machu Picchu ticket date.
Common questions about training for the Salkantay Trek
How fit do I need to be for the Salkantay Trek?
Fit enough to walk about 5.5 hours a day for 5 days with a 5 to 8 kg daypack, including an 8 to 11 hour pass day with 1,810 m of descent on day 2 and a 1,291 m ascent over Llactapata on day 4. The benchmark that matters most is the weekend pair: a long ascent, then a long descent, with knees that are fine on Monday.
How many weeks does it take to train for the Salkantay Trek?
Twelve to sixteen weeks from a base of two or three sessions a week. The hardest training weeks land three to six weeks before you fly, followed by a two week taper.
What is the hardest day of the Salkantay Trek?
Day 2, over the Salkantay Pass at 4,630 m: 22 km, 810 m up, 1,810 m down, 8 to 11 hours. Day 4 has the biggest ascent, 1,291 m over Llactapata, in 8 to 9 hours.
Is the Salkantay Trek the same as the Salkantay trail?
Yes. Salkantay Trek, Salkantay trail and Camino del Salkantay all name the same route from the road end above Mollepata over the Salkantay Pass to Machu Picchu. The classic version is five days via Llactapata; the four-day version takes a vehicle down the valley to Hidroelectrica instead.
Is the Salkantay Trek harder than the Inca Trail?
By the numbers, yes: 79 km against 45, a 4,630 m pass against 4,215 m, 4,925 m of descent against 2,460 m, and an 8 to 11 hour pass day. It has no permit quota and stays open all year.
Can I train for the altitude at sea level?
No. The pass is 4,630 m on day 2, so acclimatisation happens in Cusco beforehand; keep those two or three days. After the pass the trek stays below 3,000 m.
Do I need to train with a weighted pack?
Yes, with the 5 to 8 kg daypack you will actually carry, on every long training day. Mules carry the camp.
Do I need a permit, and when is the best time to go?
No trek permit; a local entry fee and a timed Machu Picchu ticket for day 5. The dry season is May to September and the route is open all year, unlike the Inca Trail.
Is the Salkantay Trek harder than Kilimanjaro?
Different shapes. Kilimanjaro is 7 days with one summit night at 5,895 m and a walk out. The Salkantay Trek is lower (4,630 m) and shorter (5 days) but descends 4,925 m, with three days over 1,000 m of descent and its biggest ascent on day 4. Both are won on descent-ready legs and the ability to do hard days back to back.
How hard is the Salkantay Trek?
The Salkantay Trek is 5 days: 79 km, 3,707 m of ascent and 4,925 m of descent. A typical day is about 5.5 hours with 670 m of ascent; the longest, day 2, is 8 to 11 hours with 810 m up and 1,810 m down. The high point is 4,630 m. One of the four nights is above 3,000 m, so altitude is part of the difficulty and the itinerary's acclimatisation, not your fitness, is what handles it. Porters are optional; with them you walk with a daypack of 5 to 8 kg. Mostly good mule track, with steep rocky zigzags below the 4,630 m pass on day 2 and a steep forest path to Llactapata; snow and freezing nights are possible at Soraypampa and on the pass, so acclimatise two or three days in Cusco first. There is no rope work on the standard route. In training terms the difficulty is consecutive days, the daily vertical, the descents and the pack, and 12 to 16 weeks from a base of two or three sessions a week covers it; the 16-week Salkantay Trek training plan is the fixed version.
How long is the Salkantay Trek?
The Salkantay Trek is 79 km in 5 days, about 27 to 36 hours of walking in all, with 3,707 m of ascent and 4,925 m of descent, from Challacancha (3,800 m) to Machu Picchu citadel (2,430 m). Other itineraries in the trek database: 4 days from Challacancha to Machu Picchu citadel. The plan on this page is built for the standard version in the table above; a shorter version compresses the same vertical into fewer, longer days, so it is not easier to train for.
Can I do the Salkantay Trek without training?
Not well, and for most people not safely. The Salkantay Trek asks for 5 consecutive days, about 5.5 hours and 670 m of ascent on a typical day and 8 to 11 hours on the longest, and one night at or above 3,000 m where fitness does not replace acclimatisation but is what keeps reserve for it. Untrained walkers are the ones the later days hurt: fatigue accumulates faster than fitness recovers, the 4,925 m of descent lands on quads that have never braked for hours, and the gap shows on the longest day, not the first. Twelve to sixteen weeks from a base of two or three sessions a week is enough for most people; the 16-week Salkantay Trek training plan is the fixed version and the app builds the personalised one backwards from your departure date.

The takeaway
The Salkantay Trek is rarely a fitness problem in the abstract. It is a shape problem: the people who walk into Aguas Calientes with legs to spare trained for an 8 to 11 hour pass day with 1,810 m of descent, three descending days in a row and a 1,291 m ascent on day 4, not for the Inca Trail they could not book. Train the descent and the pair, and let the days in Cusco do the altitude.
