Macro Tracking Guide for Skiers & Snowboarders: All-Day Mountain Energy

The myth writes itself somewhere around the third chairlift: "I've been riding six hours — tonight I can eat and drink whatever I want." Every ski town runs on that sentence. It is also wrong in two directions at once, and both errors cost you the rest of the week.

Direction one: a six-hour lift-served day is mostly sitting, sliding, and queueing — actual descent work might total two or three hours, and the burn is usually far below what the legend (or your watch) claims. Direction two: genuinely huge days do exist, especially touring, but altitude mutes your appetite so badly that you under-fuel the mountain and then over-correct at the bar, where alcohol's 7 kcal per gram does its quiet accounting.

Tracking macros is how you audit both errors. Here is the evidence, the resort-week numbers, and the apres math nobody does on a napkin.

1. The 'I Earned It' Myth, Audited

Resort skiing is interval exercise with very generous rest. Between lift rides, lodge stops, and traverses, a full day on the hill commonly nets a total expenditure of 2,500-3,500 kcal for an 80 kg rider — solid, but a long way from the 5,000-kcal stories. Touring days with skins, a heavy pack, and dawn starts are the real monsters, capable of 4,000-4,800 kcal.

The research on exercise and appetite explains the rest: people reliably eat back more than they burned, often without noticing, which is a major reason exercise alone fails as a weight tool. One burger, fries, two beers, and a shared dessert can settle the whole day's bill and then some.

None of this means restriction — most riders should eat a lot on mountain days. It means the only honest referee is a log plus your weekly average weight. Track one full trip and you will know whether your 'earned it' instinct runs a surplus or a deficit. Almost nobody guesses right.

2. Altitude Suppresses the Appetite You're Trusting

Above roughly 2,500 m, appetite drops while energy needs rise — a vicious combination if you eat by hunger. Add cold (which blunts thirst while breathing dry air drains fluid) and degraded altitude sleep, and your body's fuel gauges are all reading wrong at once.

The fix is eating by schedule, not sensation. Take in 30-60 g of carbohydrate per hour on snow — a gel, dried fruit, or a waffle in the jacket pocket every chairlift cycle. Anchor the day with a deliberately large breakfast: 100-140 g of carbs plus 30-40 g of protein, eaten before the appetite suppression has a vote.

Logging matters more up high precisely because hunger has stopped being data. A first-trip log usually shows mountain-day intake landing 800-1,200 kcal under target while the rider wonders why day three legs feel like wet sand. The spreadsheet catches what the stomach hides.

3. A Resort Week in Real Numbers

Mountain weeks swing harder than almost any training calendar, so the macros should swing with them — protein and the fat floor (0.6-1.0 g/kg) hold steady while carbs ride the terrain, a clean application of carb cycling. Numbers below are for an 80 kg rider.

Calorie columns are starting estimates. Log a week against your trend weight and adjust in 100-200 kcal steps — your lift pass, pack weight, and vertical make your numbers yours.

4. Apres Math: 7 kcal per Gram, Logged Honestly

Alcohol is the macro nobody tracks. At 7 kcal per gram it sits between carbs and fat in energy density, and it counts toward the day whether or not the app has a tidy field for it. A 500 ml pint of 5% beer carries about 20 g of alcohol — roughly 140 kcal — plus carbs, landing near 200-230 kcal per glass. Three pints and a shared plate of nachos run 1,100-1,300 kcal: an entire storm-day's deficit, erased between 4 and 6pm.

Log it honestly with a simple trick: divide the drink's total calories by 4 and enter them as carbs, or by 9 and enter them as fat. Either keeps the energy ledger true, which is the only thing that matters for weight.

One hard safety note: alcohol, altitude, and dehydration stack. Together they wreck already-fragile mountain sleep, deepen fluid deficits, and dull next-morning judgment on consequential terrain. Match each drink with water, and treat headache, nausea, or unusual breathlessness at elevation as a medical question — altitude illness is not a hangover.

5. Off-Season Tracking So Opening Week Doesn't Wreck You

Every December the same rider gets destroyed by day one — quads shredded by eccentric load no summer of casual lifting prepared, carrying five extra kilos of apres souvenirs from last season. Both problems are solved between May and November, and both are tracking problems as much as training problems.

Building leg strength for descent days takes a small surplus: 100-300 kcal above maintenance, protein at 1.8-2.2 g/kg, aimed at roughly 0.25-0.5% bodyweight gain per month-to-month trend. Carrying mass you do not want into the season calls for the opposite — a modest cut at 0.5% of bodyweight per week using a deficit designed to keep muscle, finished before snow flies so in-season eating can be generous.

Either way, the goal of off-season tracking is the same: arrive at opening week strong, fueled, and already in the logging habit before the chaos of travel, altitude, and apres begins.

Questions Riders Ask on the Chairlift

How many calories does a ski day actually burn?

Less than the legend, usually. A full lift-served day for an 80 kg rider typically totals 2,500-3,500 kcal of expenditure once the lift rides, lodge breaks, and traverses are counted honestly — descent time is a fraction of hill time. Backcountry touring is the exception: skinning with a pack can push 4,000-4,800 kcal. Your weekly trend weight against your log is the only burn meter worth trusting.

How do I log beer and apres food without lying to myself?

Count alcohol as the fourth energy source it is: 7 kcal per gram. Practical method — take the drink's total calories (about 200-230 for a 5% pint), divide by 4, and log it as carbs, or divide by 9 and log as fat. Either keeps your daily energy total honest. For shared plates, log your realistic fraction generously; apres portions are eyeballed in dim light by hungry people, which is how 500 kcal becomes 'a few chips.'

Does altitude change my macro targets?

It changes your behavior more than your split. Energy needs rise modestly while appetite and thirst fall, so the danger is under-eating, not the wrong ratios. Keep protein steady, push carbs toward the top of your range on big days, schedule 30-60 g of carbs per hour on snow regardless of hunger, and drink to plan rather than thirst. Persistent headache or nausea at elevation is altitude illness territory — that is medical, not nutritional.

Should I keep tracking during a five-day-a-week season?

Track loosely, anchor firmly. Full-season gram counting burns most people out; what works is holding two anchors — protein around 1.6-2 g/kg and an honest log of alcohol and restaurant meals, the two places winter intake goes invisible. Weigh in weekly under the same conditions and tighten the logging only if the trend drifts. Riders who do this maintain strength through April instead of rebuilding from scratch every May.
