Most people who book the Salkantay trek do so several months in advance, feel a quiet urgency about getting fit, and then do very little about it until three weeks before departure. This article is for those people, and also for the ones who started earlier and want to make sure they are preparing in the right way.
The goal of an eight-week training plan for the Salkantay is not to turn you into an athlete. It is to make sure that when you are standing at the Salkantay Pass at 4,630 meters at 7am on Day 2, having climbed 730 meters in the predawn dark, you still have something left for the 1,700-meter descent ahead of you. That specific requirement, sustained effort at altitude over multiple consecutive days, is what the training plan is designed to build.
Before building a training plan it helps to understand exactly what you are training for. The Salkantay Classic Trek covers 70 kilometers over five days. The Express version covers 62 kilometers over four days. Both routes involve significant daily elevation gain and loss, with the biggest single day on either version involving a total altitude change of more than 2,400 meters.
The physical demands break down into three components. Cardiovascular endurance is the ability to sustain aerobic effort over many consecutive hours, day after day, with incomplete recovery between sessions. Muscular strength and endurance in the legs, specifically the quads, hamstrings, glutes, and calves, determines how your knees and ankles hold up on steep descents and how much energy each uphill step costs you. Altitude tolerance is partly physiological and partly a function of fitness, since a more efficient cardiovascular system handles reduced oxygen availability more effectively than an untrained one.
The training plan below addresses all three components progressively over eight weeks.
In Week 1, before beginning the structured plan, do one honest assessment walk. Put on the boots you will wear on the trek, add a daypack with five or six kilos of weight, and walk for three hours on varied terrain that includes at least one sustained uphill section. Note how you feel at the end: how your feet are, whether your hips or knees are complaining, how breathless the uphill sections make you, and how long it takes to recover.
This walk serves two purposes. It tells you honestly where your current fitness level sits, which determines how hard to push in the early weeks of the plan. It also identifies any footwear or gear issues, blisters from new boots, an ill-fitting pack, chafing from clothing, while there is still time to address them before the trek.
The first two weeks are about consistency rather than intensity. Three sessions per week, each between one and two hours, on terrain that is accessible and reasonably varied. The goal is to establish the habit of regular walking and to begin conditioning your feet, ankles, and legs to sustained effort.
Walk at a pace you can maintain comfortably for the full duration of each session. If you are breathing too hard to hold a conversation, slow down. At this stage building aerobic base requires effort at a moderate intensity sustained over time, not maximum effort over a short period. Every session should be done in the boots you will use on the trek.
Introduce a light daypack from the first session. Five kilos is enough for this phase. The weight conditions your shoulders, hips, and posture to the loaded walking position and accelerates the breaking-in process for both the boots and the pack.
By the end of Week 2 you should be able to walk for two hours with a light pack on moderate terrain without significant fatigue in the final section. If that is not the case yet, extend Week 2 rather than moving to the next phase.
Weeks 3 and 4 shift the focus from flat distance to elevation gain. Hills, stairs, and inclines become the primary training tool. The cardiovascular and muscular demands of uphill walking are disproportionately greater than those of flat walking at the same pace, and the descent from the Salkantay Pass involves a kind of muscular effort, sustained eccentric load on the quads, that flat terrain training does not adequately prepare for.
Increase to three or four sessions per week. At least two of those sessions should involve sustained uphill sections of 30 minutes or more. If you live in a city without easy access to hills, stair climbing is a highly effective substitute. A building with fifteen to twenty floors of stairs, climbed and descended repeatedly for 45 to 60 minutes, provides an excellent simulation of the elevation demands of the trek.
Increase the pack weight to seven or eight kilos in Week 4. This is approaching the maximum weight you should be carrying on the trek itself and training with it builds the specific muscular and postural conditioning that trail weight requires.
Begin including one longer session per week in Week 3, aiming for three to four hours on terrain that includes both ascent and descent. Pay specific attention to how your legs feel on the downhill sections. Quad soreness the day after a long descent is normal and indicates that the training is working. Knee pain on the descent itself is a warning sign worth addressing before it becomes a problem on the trek.
These two weeks are the most important of the entire plan and the phase most commonly cut short when life becomes complicated. Do not cut them short.
The key addition in Week 5 is one long walk per week of five to six hours on the most varied terrain you can access. This session simulates the demands of the longer days on the trek and builds the specific endurance that multi-hour sustained effort requires. It is qualitatively different from the shorter sessions and cannot be substituted with three shorter walks in the same week. The five-hour continuous effort is the point.
Maintain three to four shorter sessions through the week alongside the long walk. These sessions can be reduced to 60 to 90 minutes but should continue to include elevation where possible.
In Week 6, push the long walk to six to seven hours. Pack it as if you were actually going on the trek, with the weight you plan to carry and the footwear and clothing you will use. Eat on the walk the way you will eat on the trail, snacking at regular intervals rather than stopping for a full meal. This trains your digestive system alongside your cardiovascular system.
By the end of Week 6 you should be able to complete a six-hour walk on varied terrain, including sustained uphill and downhill sections, and feel tired but functional at the end of it rather than completely depleted. If you feel completely depleted, extend this phase by a week before moving to the final phase.
The final two weeks consolidate the fitness built in the previous six weeks and then taper the training load to allow your body to arrive at the trek rested and ready rather than tired and sore.
Week 7 maintains the training volume of Weeks 5 and 6. One long session, several shorter sessions, and a continued focus on elevation and pack weight. The difference from Week 6 is that you are now doing this at a fitness level that is meaningfully higher than when you started, and the sessions that felt hard in Week 3 should feel manageable now.
Week 8 is a taper week. Reduce the total volume of training by roughly 40 percent. Keep the frequency of sessions but shorten the duration of each one. The long walk drops to three to four hours. The shorter sessions drop to 45 to 60 minutes. The goal is to maintain the conditioning you have built without adding fatigue that will take more than a week to clear.
Stop all training three days before the trek begins. Use those days for travel, acclimatization in Cusco, and rest. A training session two days before the trek does not add fitness. It adds fatigue that will still be present when you start walking.
Walking is the primary training tool for this trek but cross-training adds value in several specific ways.
Cycling builds the cardiovascular base and the leg strength that the trek demands without the impact load of walking. It is particularly useful for people whose knees are sensitive to high mileage on foot and who need an alternative way to build endurance without aggravating existing issues.
Swimming develops cardiovascular efficiency in a way that is highly transferable to altitude performance. The breathing control required in swimming and the cardiovascular demands of sustained lap swimming build the aerobic base that altitude reduces and that fitness can partially offset.
Stair climbing on a machine or in a building is the most direct simulation of the ascent demands of the route and the most accessible for people in urban environments without nearby hills. Thirty to forty-five minutes of sustained stair climbing with a pack is among the most efficient single training sessions available for this specific trek.
Yoga and stretching reduce injury risk significantly on multi-day treks by maintaining the flexibility and joint mobility that sustained daily walking demands. Hip flexors, hamstrings, and calves are the areas most likely to create problems on the Salkantay and a consistent stretching routine through the training period addresses this directly. Twenty minutes of stretching after each training session is more valuable than most people expect.
Strength training focused on the lower body complements the walking program without replacing it. Squats, lunges, step-ups, and single-leg exercises build the muscular strength that supports the knees and ankles on steep descents. Two sessions per week during the early phases of training, reduced to one per week in the later phases, is sufficient.
Training only on flat terrain is the most frequent error and the one with the most direct consequences on the trek. Flat walking builds cardiovascular base but does not prepare the specific muscles used on steep descents, and does not train the balance and proprioception that uneven mountain trail demands. If your training environment is predominantly flat, compensate with stair work and incline treadmill sessions.
Training in different shoes than the ones you will use on the trek is a mistake that announces itself as blisters within the first few hours of Day 1. Every training session should be done in the boots you will wear on the Salkantay.
Starting too hard in the first two weeks and accumulating fatigue that affects the quality of subsequent training is common among motivated trekkers who underestimate the importance of the base-building phase. The first two weeks should feel almost too easy. That is correct.
Skipping the long sessions in Weeks 5 and 6 because they require significant time is the error with the most direct impact on trek performance. Everything else in the plan builds toward those long sessions. They cannot be replaced by additional shorter sessions.
Six weeks is manageable if you compress the base-building phase and begin at a moderate intensity from the start. Four weeks is tight but better than nothing, focusing exclusively on elevation training and long sessions. Fewer than three weeks of preparation for a physically demanding trekker who is already reasonably fit can still be meaningful. Fewer than three weeks for someone starting from a low baseline is not enough time to prepare adequately and the expectation going into the trek should be adjusted accordingly.
Whatever time you have, use it. A month of consistent preparation is dramatically better than no preparation, regardless of where it sits relative to the ideal eight-week timeline.
