A serious ski week is not a vacation. It is a training block – thirty to fifty hours on skis across seven days, in conditions that punish the unprepared and reward the patient. Here is what the week actually looks like, how to train into it, and what the marketing leaves out.
The 4-on-1-off pattern.
This is the rhythm a former competitive skier defaults to. Four full days of skiing, one full rest day, then two more days back on snow. Sometimes 3-on-1-off-3 if the conditions cluster early in the week. The 7-on format – skiing all seven days without a rest – is what recreational tourists do because they feel like they are wasting the trip. By day five they are skiing tired, their technique is degrading, and the injury risk on day six and seven is significantly elevated.
The rest day is not optional. It is the day your quads recover from the eccentric loading of three or four hard days. It is the day you walk through town, get a long massage, sit in the chalet sauna, eat a real meal at 1pm instead of a bowl of soup at 11:45 on the mountain. The strongest skiers I have known all build this day in. The weekend warriors push through and pay for it on the back half.
Inside each ski day, the structure matters too. First chair at 8:30 or 9, hardest terrain in the morning while your legs are fresh and the snow is firm, lunch at 12:30 (carbs and protein, real food, not a Snickers), one or two more runs in the afternoon, off the mountain by 3:00 or 3:30. The afternoon light goes flat by 3 and the snow softens past the point of usefulness. You gain nothing from the last hour and you lose your morning the next day.
Pre-trip fitness.
This is the difference between the week you remember and the week you survive.
Eight weeks out. Heavy lower-body posterior chain work twice a week – back squats, RDLs, single-leg work. Three days of moderate aerobic – 45 to 60 minute zone 2 sessions on the bike or the rower. Skiing requires sustained eccentric quad loading and a strong posterior chain to absorb the impact loads. If your training has been all upper body and conditioning, you will get destroyed by Wednesday.
Four weeks out. Add sport-specific work. Box jumps and lateral bounds twice a week for the explosive component. Wall sits – genuinely brutal, two minutes at a time – for the isometric quad endurance that matters on a long steep descent. If you have access to a slide board, that is the single most ski-specific piece of equipment available indoors.
Two weeks out. Taper. Drop the volume by a third, maintain intensity. Get your sleep in order. Travel rested.
This is what serious skiers actually do. The recreational version – showing up unprepared and treating the first three days as the warm-up – is how you blow an MCL on day four when you are tired and the snow turns to mashed potatoes.
Avalanche certification.
If you are skiing inside the resort boundary on patrolled terrain, you don’t need this. If you are stepping outside the rope for any reason – even one run with a guide – you do.
In North America, the path is AIARE 1 – a three-day course offered through any of two hundred AIARE providers, ranging from the AAI (American Alpine Institute) in Bellingham to local providers in Jackson, Tahoe, Salt Lake. The course covers terrain recognition, snowpack evaluation, the formal decision-making framework, and companion rescue. Cost is $450 to $650 and the course runs throughout the winter.
In Canada, the equivalent is the CAA AST 1 (Avalanche Skills Training) – same curriculum, different acronym, recognized internationally. Offered through Canadian outfits like Yamnuska, Selkirk Mountain Experience, ACMG-certified guides.
In Europe, the structure is different. There is no single course that covers the continent. France runs the FFCAM curriculum. Switzerland runs the SAC. Italy runs the AINEVA. Most serious European backcountry skiers either take the local course in the country they ski most or work with IFMGA-certified guides who effectively re-teach the curriculum on every trip.
The certification is not a permission slip. It is the vocabulary that lets you have a useful conversation with the guide, read the avalanche bulletin without misinterpreting it, and make better terrain choices on the days the guide is not with you. Take it once. Refresh every three years with an AIARE 2 or its European equivalent if you progress into more committing terrain.
Heli-skiing operator vetting.
Heli is the premium tier of the discipline, and the operator matters enormously.
RMR (Selkirk Tangiers Heli Skiing) – Revelstoke, BC. Day-trip and multi-day operation out of town. The simplest entry into heli for a strong skier who is not ready to commit to a week-long wilderness lodge operation. Per-day pricing in the $1,400 to $1,800 range. Quality operation, well-run safety culture.
CMH Cariboos (Canadian Mountain Holidays) – multiple BC lodges. The original heli-skiing operator, founded by Hans Gmoser in 1965. CMH operates ten lodges across British Columbia, each in a separate tenure with its own terrain character. CMH Cariboos is the flagship – vast terrain, alpine bowls and tree skiing, the operation that produced the heli-skiing tradition. Week-long, lodge-based, $14,000 to $18,000 per person all-inclusive. The food, the guides, the daily routine – all dialed.
Mike Wiegele Heli Skiing – Blue River, BC. Founded by Mike Wiegele in 1970, second-oldest after CMH. The Blue River tenure is famous for steep tree skiing and consistent powder. The operation runs Bell 212 helicopters – larger machines that move four-skier groups efficiently. Week-long format, $15,000 to $20,000 per person.
Bella Coola Heli Sports – Bella Coola, BC. Coastal BC, dramatic terrain, often regarded as the best big-mountain heli skiing in the world for expert skiers. Tantalus Lodge and other satellite operations. This is not entry-level heli – the lines are committing, the runs are long, and the terrain selection requires strong skiers who can handle steep variable snow. $20,000 to $28,000 per person per week and worth it if your skill matches the terrain.
Vetting framework: ask the operator the guide-to-skier ratio (a real operation runs 1:4 minimum), ask how many guides are IFMGA-certified versus ACMG-only, ask the snow safety protocol (are they bombing the start zones, are they running structured terrain morning meetings), ask the helicopter type and pilot hours in mountain operations. If they cannot answer these questions cleanly, the answer is not good.
Touring fitness.
If the trip includes any ski touring – even a half-day – you need separate preparation. Touring is uphill aerobic work in heavy boots with skins on the skis, often at altitude, for one to four hours at a stretch. It is closer to a long mountain bike climb than to downhill skiing.
Pre-trip, add one weekly long zone 2 session of 90 minutes to two hours. Bike, treadmill on incline, weighted ruck up actual hills if you have them. The cardiovascular base is what carries the climb, not the leg strength. Strong skiers who skip the aerobic prep blow up on the first climb and spend the rest of the day cooked.
The altitude conversation.
This is the honest one most ski writing avoids.
Vail base is at 8,150 feet. The top lift is 11,570. Las Lenas tops out at 11,253. Portillo is 10,860 at the base. The Klein Matterhorn at Zermatt is 12,740. If you fly in from sea level and start skiing the next morning, you will feel it – headache, shortness of breath, degraded recovery between runs, poor sleep the first two nights.
The fix is not Diamox unless you are going significantly higher (Diamox has its own side effect profile). The fix is hydration, two nights of acclimatization at altitude before you start skiing hard, and the honest acceptance that your first two days will not be your best. Hydrate aggressively – the dry mountain air pulls fluid out of you faster than you notice. Avoid alcohol the first two nights. Sleep in the room with a humidifier if the hotel has one.
If you are going above 12,000 feet for ski-mountaineering objectives, the protocol changes – real acclimatization schedule, possibly Diamox in advance, possibly a hypoxic tent at home in the weeks before. That is a different conversation. For standard resort and heli operations, two days at altitude is enough.
The week, summed.
Prepare for eight weeks. Travel rested. Ski four days, rest one, ski two more. Pre-take the avalanche course if you are stepping outside the rope. Vet the heli operator like you would vet a surgeon. Hydrate harder than you think. Sleep more than you think.
This is the week the strong skiers run. It is not the week the marketing sells. The discipline is in the structure.
