Everything athletes ask us before they start training with Train to Mountain. If you have a question we have not answered, the founder reads every reply at info@traintomountain.com.
Train to Mountain is an adaptive training app for athletes with a real mountain objective. You tell it your peak, your timeline, and where you are starting from. It builds you a personalised training plan, then adapts that plan every week based on what your body actually does, not what an off-the-shelf program assumes.
We are also expanding TTM to support ongoing maintenance training between objectives, so the fitness you build does not have to start from zero every time.
TTM is built for athletes preparing for objectives in the 3000-5000m (9,800-16,400 ft) range. Mountains where the difference between summit and turnaround is fitness, not luck. If you have a specific peak or route in mind, the enthusiasm and motivation to start, and you are taking it seriously, you are in the right place.
TTM is not built for elite expedition climbers. And if you are a weekend hiker without a specific summit in mind, we are also building a parallel program for ongoing year-round mountain training rather than peaking for one summit, so you have a home with us too.
Your plan is built from three inputs: your objective (peak, route, summit-day demands), your timeline (how many weeks until you go), and your starting fitness (assessed in onboarding and refined every week).
The algorithm uses a polarised 80/20 training distribution backed by endurance research, tunes load progression to your individual response, and rebuilds next week's plan every Sunday based on what you completed and how you felt.
A great human coach is a real relationship. They know your patterns, push you when you need it, and adjust your plan as your life and your training move.
TTM is built to give you the structural side of that work, periodisation, weekly adaptation, honest readiness checks, in an app that costs less than hundreds of dollars a month. If you have access to a great coach, use one. If you do not, TTM is built to put the same training discipline within reach.
Three things, in the order that matters:
Not a full gym, but you do need access to incline cardio equipment, a treadmill that goes to at least 12% or a Stairmaster, plus a small bit of floor space for bodyweight strength sessions. Outdoor vertical (stairs, hills, trails) covers a lot of the work too.
Living near real hills or mountains is, of course, the ideal setup, the terrain itself becomes part of the training plan. If you have a full gym, even better. We will layer heavier strength sessions into your plan. If your access is limited to one piece of incline cardio plus bodyweight, the plan still works.
Yes, within the limits of what is possible at sea level. The plan builds the aerobic base, hypoxic tolerance training, and pacing discipline that load the same physiological systems altitude exposes.
What no app can give you is actual altitude exposure. That comes from acclimatisation rotations on the mountain itself. We tell you exactly what to do in the weeks and days before you fly out, and what to expect once you arrive (see our full altitude acclimatisation guide for more).
It depends on your starting fitness, your objective, and how much time you have. As a rough rule, a 4000m (13,100 ft) alpine peak with a reasonable base needs at least 12-16 weeks of structured training. A more demanding objective needs more.
The honest way to find out for your specific peak is to run our Summit Simulator. Tell it your objective, your current fitness, and your timeline, and it tells you whether you have enough runway, what you need to fix, and where to start.
Every Sunday. At the end of each week, the algorithm looks at what you completed, how it went, and how your body responded. Then it rebuilds the next week's training to match.
The same adaptive engine handles real life too. When you have a trip, a busy work week, an injury niggle, or anything else that breaks the rhythm, the plan reshapes around it instead of pretending it did not happen. That responsiveness, training to what your week actually looks like, is the heart of what we mean by adaptive.
Weekly is the cadence the training science supports, and it is responsive enough to hold up against how athletes actually live.
Mountains in the 3000-5000m (9,800-16,400 ft) range where summit success depends on fitness. Alpine 4000m (13,100 ft) peaks, Andean objectives, Caucasus and Atlas summits, Himalayan trekking peaks with technical sections.
If your objective involves a long approach, sustained vertical, exposure, and a real descent, you are our audience.
Yes. TTM connects to the wearables most athletes already use, including Garmin, Coros, and Suunto. Your training data flows in automatically, which gives the algorithm the signal it needs to adapt your plan precisely.
If you do not own a wearable, you can also log workouts and how they felt directly in the app.
Yes. TTM is built so any athlete with a real mountain goal can start, whatever your current fitness level looks like. The plan meets you where you are and grows from there.
If you are newer to structured training, the first weeks focus on building your aerobic base safely before the load ramps up. If you already have a strong base, we move you into objective-specific work sooner. Either way, the early phase is about understanding your body so the plan can adapt to you, not the other way around.
Right now, nothing. TTM is in beta, and the first wave of users get full access free while we refine the algorithm. We are open about the trade: access in exchange for honest feedback.
Once we move out of beta, early beta users continue at a minimal cost that only covers the running costs of the platform.
Honest answer: TTM is in beta, and we are explicit about that. What we can stand behind is what the methodology rests on - peer-reviewed endurance research (Seiler's polarised distribution, the Banister model, Mazzeo's altitude work, LaStayo's eccentric loading), weekly Sunday adaptation cadence, and personalised plans built from your peak, your timeline, and your starting fitness.
Beta is free; the trade is honest feedback in return for full access. That is the bar we are inviting athletes to judge us against. The product will mature; the methodology is already there.
Personalised mountaineering training is a training approach where the plan rebuilds week by week from what you actually did, instead of following a fixed program. It is built on polarised intensity (Seiler & Kjerland, 2006) and the Banister fitness-fatigue model (Banister et al., 1975 & 1991).
See the full guide on personalised mountaineering training for the science, the practice, and how it works at TTM.
Polarised 80/20 means roughly 80 percent of your weekly training is at low intensity (zones 1-2), and 20 percent is at high intensity (zones 4-5). The middle ground (zone 3) is intentionally minimised. The research base for this distribution comes from Seiler & Kjerland (2006), who showed it produced better endurance adaptations than evenly-distributed or middle-heavy schedules.
Mountain athletes benefit because the 80 percent builds the aerobic engine summit days demand, while the 20 percent develops the top-end fitness needed for steep sections and high altitude. See our heart rate zones guide for the details.
Most of your training should be in zone 2 (60-70 percent of max heart rate) - this is where the body builds capillary density, mitochondrial volume, and fat-burning capacity. About 15-20 percent of training sits at zone 4-5 (threshold and VO2max work). Zone 3, the moderate-intensity grey zone, gets minimised because it costs you the recovery you need for both the long zone-2 work and the hard intervals.
We have a full guide that walks through how to calculate your zones and structure a week.
Three big differences. First, vertical: a summit day involves 1500-2500m (5,000-8,200 ft) of climbing and descending, where a marathon is essentially flat. The aerobic system that handles relentless uphill is built differently. Second, eccentric load: descents punish the legs with eccentric forces 4-6 times bodyweight (LaStayo et al., 2003), and an unprepared descent ends careers. Third, altitude: a marathon runs at sea level where oxygen is 100 percent; many mountain objectives sit at 50-60 percent.
TTM trains all three, where a marathon plan trains only the first. See our guide on training for mountaineering for the full picture.
The Banister training-impulse model (Banister et al., 1975 & 1991) describes how every training session leaves two opposite traces - fitness (slow to build, slow to decay) and fatigue (quick to build, quick to fade). Your readiness on any given day is fitness minus fatigue.
The model lets us predict when an athlete will be peaked (high fitness, low fatigue) and when a deload week is needed. TTM uses Banister-derived calculations to time your taper and decide each week whether to add load or back off. The full methodology page walks through this in depth.
For a 4000m (13,100 ft) alpine peak with a reasonable base, plan at least 12-16 weeks of structured training. The plan needs to build four things in parallel: an aerobic engine (zone 2 sessions, progressive long efforts), vertical gain capacity (incline cardio, hill repeats, weighted carries), summit-day specificity (back-to-back long days simulating ascent + descent), and eccentric descent loading.
Altitude prep at sea level is limited but real - the same physiological systems get loaded by zone 2 volume and hypoxic tolerance work. See the Summit Simulator for an honest readiness check on your specific peak, or browse our peak-by-peak training pages for the alpine 4000m you have in mind.
Three checks. First, can you sustain the summit-day effort at sea level? A practice day with the same vertical and duration as your objective tells you a lot. Second, have you tested your descent capacity? A heavy descent day late in training reveals whether your legs can handle the eccentric load. Third, do you have enough acclimatisation runway built in? The body needs 10-21 days of altitude exposure for meaningful red blood cell adaptation (Mazzeo, 2008).
The Summit Simulator turns these checks into a readiness score for your specific peak.
For a 4000m (13,100 ft) alpine peak, start 12-16 weeks out if you have a reasonable base of regular cardio. For 5000-6000m (16,400-19,700 ft) objectives, start 16-24 weeks out, factoring in extra time for vertical capacity building and altitude prep. If you are coming from no recent base, double those timelines.
The honest answer for your specific case lives in the Summit Simulator - give it your peak, your timeline, and your current fitness, and it tells you whether the runway works or where the gap is.
Summit readiness is a measurable score for whether your body has done the work your specific peak requires. It rolls four things into one number: aerobic capacity (can you sustain summit-day effort), vertical capacity (can your legs handle the gain), descent tolerance (can they survive the way down), and altitude prep (is your acclimatisation plan sufficient).
Run the Summit Simulator, enter your peak and your timeline, and you get a score plus the gap to close. Knowing this beats guessing, which is what most athletes do.
Descent training is eccentric-load training - the muscles lengthen under load rather than shorten. LaStayo et al. (2003) showed eccentric work generates 4-6 times bodyweight in force at the knee, which is why descents destroy the underprepared.
The plan layers progressive downhill repeats, controlled step-down sessions, weighted carry work on descents, and (where you have the terrain) back-to-back days that mimic the cumulative fatigue of multi-day climbs. See our eccentric training guide for the full protocol.
Yes. TTM is built specifically for athletes whose training has to fit around a real life. The plan asks how many hours per week you have, then optimises within that. A typical full-time-job athlete trains 5-7 hours a week and still summits 4000m (13,100 ft) peaks reliably.
The adaptive engine reshapes around busy weeks, travel, and illness instead of pretending they did not happen. The trade-off is timeline - 5 hours a week needs more total weeks than 10 hours a week. The Summit Simulator shows you what is honest for your hours.
