Pick the line that best sums up your fitness right now, whether that's from walking or another sport entirely: the tool works out the climbing you can hold day after day, places your nights at the tour's real accommodation, and balances the days out. Shortcuts by tramway, bus and cable car change everything, that's the one lever Mont Blanc has that most treks don't, covered in the full article.

Good call!
Sorting it yourself is still the best way to make the tour your own, and the breakdown above is a solid base to work from. On the TMB, the real constraint isn't your fitness, it's booking: July and August huts fill up as early as January. Contact details and booking methods for the tour's fifty-odd places to stay are on our dedicated page. Enjoy the loop!

Go with a guide
Our guides take small groups around Mont Blanc every summer, in comfort format with luggage transport. Leave your details and we'll send you our upcoming departures.
One July evening at the Refuge Bonatti, two tables compare notes over dinner. On one side, a group is wrapping up the tour in 7 days: cable car out of Chamonix, two buses on the Swiss side, hotels the whole way. On the other, a second group is on day nine of twelve, hauling a 12 kg pack, on foot the entire way from Les Houches. Both will tell you they did "the Tour du Mont-Blanc." It's not really the same trip.
How many days, or how much time, does the Tour du Mont-Blanc take? The short answer doing the rounds online is 7 to 10 days. It's not wrong, just half the story, because it lumps together two quite different things: the number of days spent walking, and the number of days on tour. In between, there's transport and variants to factor in.
Here are the main duration benchmarks, and the tool at the top of the page works out yours by placing your nights at real accommodation:
10 to 12 days for the full loop on foot, no transfers at all
10 days at the classic pace, the most comfortable format
7 to 9 days using tramway, bus and cable car shortcuts
5 days in condensed form, for very well-trained walkers
3 to 5 days if you're after half the tour rather than the full loop (or you're running it)
These five benchmarks are just a starting point: mix and match the variants, the shortcuts, the direction of travel and the starting point, and the tool spits out 6,453 distinct breakdowns, 811 of them without touching a single form of transport.
At Altimood, we lead Tour du Mont-Blanc trips every summer, and this question kicks off every single one of them. It deserves better than a round number.
The TMB is the go-to trek for a first big trip on foot, and that's exactly where it gets tricky
The Tour du Mont-Blanc is, by a fair margin, the most walked trek in the Alps. Plenty of people who take it on have never done a multi-day walk longer than two or three days. That's completely doable, but it shifts the real question along.
For an experienced walker, the question comes down to "how much climbing can you handle in a day?" When you're getting ready for your first big walk, you genuinely have no idea, and if you're coming from running or cycling rather than the hills, even less so. That's why the tool at the top of the page doesn't lead with that question: it asks what you're doing today, whatever the sport, and works out the rest from there. Our GR54 calculator, on the other hand, starts straight in with the climbing you can handle per day: you don't end up on the Tour des Écrins by accident, and anyone taking it on generally already knows what elevation gain means.
One useful thing to know if you're coming from another sport rather than walking: the engine carries over, the rest much less so. A regular runner or cyclist has the lungs for a climb, but not necessarily the thighs or posture for a three-hour descent, or the shoulders for an eight-kilogram pack. And it's the descents and the carrying that bring on the third-morning aches, not the climbing itself. Hence the "I'm active, but rarely in the mountains" line in the tool: it's worth noticeably more than "I do a bit of walking, nothing flash," without quite matching "I hike every week." The full rundown of what carries over and what doesn't is in our article on the daily climbing to aim for when you're starting out.
The number worth remembering: the TMB adds up to 9,000 m of cumulative climbing. Spread over 12 days, that's 750 m a day, comfortably within reach for a regular walker. Spread over 7 days, that's 1,300 m a day for a full week, pack on your back, which is a different level of commitment altogether.
What does the TMB actually measure: 158 or 170 km?
Across our eleven GPX tracks, joined end to end: 158.5 km and 9,089 m of climbing. Other tracks you'll find online also land around 160 km. Depending on the walker, an iPhone or a GPS watch will show a higher or lower number again.
Where does the gap come from? Two different places, and it's worth not mixing them up:
On distance, track sampling cuts corners slightly on switchbacks, shaving a few hundred metres off each stage. The rest comes from breakdowns that stack up stages rounded upwards and fold in variants.
On climbing, it all comes down to smoothing. The same track gives 11,151 m unsmoothed (GPS noise inflates every little bump) and 9,089 m smoothed. The 10,300 m figure sits between the two. None of these numbers is dodgy, they're simply not measuring the same thing.
These gaps aren't trivial: 12 km is half a day's walking, and 1,200 m of climbing is a full day. On a 7-day schedule, that matters. The tool calculates from the measured values, so you'll know where they come from and how to read the difference once you're out there.
Shortcuts: the lever other treks don't have
This is what really sets the TMB apart from the GR54 or the traverse of the Vercors Hauts-Plateaux. On those routes, if the days get too tough, the only option is to walk more or wild camp. Around Mont Blanc, the tour crosses three well-equipped countries: a tramway, Swiss postal buses every quarter hour, cable cars. Skipping a section isn't cheating, it's standard practice, even on organised trips.
The four shortcuts built into the tool correspond to real, bookable services:
Shortcut
What it skips
Saving
Tramway du Mont-Blanc
the climb from Les Houches to Col de Voza, up the ski runs
−6.8 km, −708 m
Postal bus La Fouly → Champex
the flat floor of the Swiss Val Ferret, easy and unremarkable
−15.4 km, −443 m
Postal bus Champex → Trient
the Bovine alpine pasture and the Col de la Forclaz
−15.2 km, −726 m
Flégère cable car
the long final descent to Chamonix
−15.5 km, −660 m
Together, the four take out 53 km and 2,500 m of climbing, roughly three to four days' worth. That's exactly what lets a regular walker knock over "the Tour du Mont-Blanc" in a single week of leave, flights included.
Fair's fair: our own 7-day trip works the same way, but it leans on private transfers. Stages of 4 to 6 hours, climbs of 600 to 1,200 m, hotel nights, luggage carried for you, and four transfers. A 7-day TMB with no transfers at all takes around 1,300 m of climbing a day, pack on your back: that's an entirely different exercise.
Worth flagging: if you see "TMB in 7 days" advertised somewhere with no mention of transfers, ask for the day-by-day breakdown before you book.
Which shortcuts should you pick? The ones that skip the least varied or most built-up sections, not the high balcony trails. The first three in the table replace a climb up ski runs, flat valley floor, and the Bovine pasture. The balcony route between Refuge Bertone and Refuge Bonatti, facing the Grandes Jorasses, or the climb to the Grand Col Ferret: those are the reasons you signed up in the first place. Leave them in, unless you're genuinely tight on time (and if you are, why not split it over two trips instead?).
The full TMB on foot: 10 to 12 days
The whole loop, on foot, without hopping into a single vehicle: that's what the tool calculates first. For a regular walker who can handle 1,100 m of climbing a day, that works out at 12 days with days of 4 to 6 hours. For someone who has already backed up several trek days and can absorb 1,400 m, that tightens to 10 days, though the days stretch to 7 hours of walking.
Where does the gap with the eleven stages everyone quotes come from? From the fact that those eleven stages aren't days at all. It's a descriptive grid, built around the accommodation, and its days are wildly uneven: from 3 hours to more than 8. Almost nobody walks it exactly as laid out, and mixing the two up leads to missed bookings.
The other reason for the gap comes down to how you count. Climbing alone is misleading: 1,350 m of pure ascent tires you less than a day of 1,100 m up followed by 1,100 m down, where the legs pay twice over. So the tool works out a walking time, with climbing and descending counted at different speeds, then looks for the breakdown that best balances the days between accommodation that actually exists. The stages we cover one by one in the full article on the tour follow the classic grid. The tool, on the other hand, builds yours from scratch, and factors in the eleven TMB variants if you want to see what they do to your breakdown.
One constraint nothing can smooth away: bed availability. The loop has around fifty places to stay, and the most in-demand fill up as soon as booking opens, often six months out. So you don't end up with your ideal breakdown, you work with what's left. One day stretches because the halfway hut is full, the next shortens because the following one is too, a variant drops out because it passes well clear of the only place you had a bed. Book first the nights where only one or two places exist: those are what lock everything else into place. Our roundup of the Tour du Mont-Blanc mountain huts maps them out with altitude, comfort level and opening dates, so you can spot the tight sectors straight away.
One last tip, and it's the one we give most often: plan for less than you think you can manage. A comfortable day can always be stretched on the spot, just add a high-altitude variant when the weather and your legs are up for it. The reverse doesn't work. A breakdown built around your best day leaves no room for a storm rolling in at 2pm, a knee that starts complaining, or the third day in a row catching up with you. All that's left then is the transport shortcut, and it's better if that's a treat you're giving yourself rather than an escape hatch.
Finally, it's the most demanding format when it comes to leave: allow two full weeks, including travel from home to the Arve valley, and if you're flying in from Australia, tack on a spare day either side for the long-haul flight and the jet lag.
The TMB in 10 days: the classic pace
At 15 km and 900 m of climbing a day on average, days last 5 to 7 hours. You reach the hut in mid-afternoon, there's slack left on mornings when a storm forces an early start, and you can afford variants like the Lac Blanc without watching the clock.
It's the format we recommend most often to regular walkers who want to see the tour, not just tick it off. We've set it out stage by stage, along with the variants this pace opens up, in our article on the Tour du Mont-Blanc in 10 days.
One or two shortcuts are then enough to bring the trip down to 8 or 9 days if leave is tight.
The TMB in 5 days: the condensed version
25 to 30 km a day, transfers to skip whole sections, and days that run past 8 hours. This format exists, and it works, but it's for very well-trained walkers who know exactly how their body handles four big consecutive days.
We've set out what it really costs, and what it makes you miss of the tour, in our article on the Tour du Mont-Blanc in 5 days.
Short on leave? Do half the tour
It's the advice we give most often, and the one people follow least. If you've got four or five days and don't walk much otherwise, a half-loop taken at an easy pace will leave you with a far better memory than the full loop rushed through.
The tour splits naturally in two at Courmayeur and Chamonix, both well served and linked by the tunnel:
French and Italian side (Les Houches → Courmayeur): the Col du Bonhomme and Col de la Seigne, the Val Veny, the south face of Mont Blanc. Four to five days.
Italian and Swiss side (Courmayeur → Chamonix): the Grandes Jorasses balcony route, the Grand Col Ferret, the Swiss alpine pastures, Col de Balme. Four to five days.
One summer for each, and you'll have done the full tour without ever needing two weeks off in one hit. It's also the best way to gauge yourself before committing to the full loop, especially handy if you're weighing up a long trip from this side of the world.
If your main goal is to prepare, a shorter multi-day walk is still the best test run, and it's day 3 that tells you the most. Our article on the daily climbing to aim for gives ranges by profile, and a 3-day walk with hut stays is enough to place yourself.
What can throw the schedule out
Fully booked huts. By far the number one cause of a wrecked schedule on the TMB, ahead of fitness. In high season, the tour's huts show full from early in the year. Book before you lock in your stages, not the other way round. The full accommodation list has contact details and booking methods.
Early-season snow patches. In late June and early July, the Col des Fours and the Fenêtre d'Arpette can still be under snow. Our page on when to do the TMB breaks the windows down month by month.
Summer storms. The rule of crossing passes before 1pm can shorten a stage planned as a double day. A spare day in the schedule isn't a luxury in July and August.
Pack weight. Self-sufficient with tent and stove, progress slows noticeably, especially downhill. Note that wild camping is regulated across a large part of the route: see our page on bivouacking around Mont Blanc before building a schedule around it.
Three currencies. France, Italy, Switzerland. Swiss huts cost noticeably more, and not all of them take cards.
Doing the tour with a guide
The number of days also depends on who's handling the logistics. On a guided trip, the stages are calibrated, huts and transfers booked before departure, and luggage follows by road. A few variants get added in to take in an edelweiss patch or a spot where chamois are regularly seen.

Frequently asked questions
How many kilometres a day on the Tour du Mont-Blanc?
On a full 12-day tour, the average works out at around 13 km and 750 m of climbing per day. Over 10 days, it climbs to around 16 km and 900 m. Over 7 days with transfers, stages run around 15 to 18 km for 600 to 1,200 m. Distance on its own is misleading: an 11 km stage crossing a pass demands more than an 18 km stage along a valley floor.
Does the Tour du Mont-Blanc really cover 170 km?
Our eleven tracks joined end to end give 158.5 km for 9,089 m of climbing. The 170 km figure you'll often see quoted comes down to three things: stage rounding, variants folded into the breakdown, and above all elevation smoothing. The same track gives 11,151 m unsmoothed and 9,089 m with standard 7-point smoothing.
Can you do the Tour du Mont-Blanc in 7 days without transfers?
It's doable but a big ask: you need to hold around 1,300 m of climbing and 23 km a day for a full week, pack on your back, meaning days of 8 to 9 hours. Almost every 7-day package on the market, ours included, actually uses bus or cable car transfers to skip sections. If a 7-day offer doesn't detail its transfers, ask for the day-by-day programme.
Does the TMB take more days than the GR54?
No, fewer. The TMB can be done in 10 to 12 days on foot, while the GR54 takes 12 to 13 days: the Écrins loop is longer (188 km) and climbs 11,000 m over more technical terrain, with fewer resupply points. The TMB has one thing the GR54 doesn't, though: public transport all along the route, which lets you tighten the trip without lengthening the days.
Should you build in a rest day on the Tour du Mont-Blanc?
On formats of 10 days or more, a half-day break at Courmayeur or Champex-Lac often changes the second half of the tour for the better. Both villages let you restock, sleep down in the valley, and get some washing done. If your schedule is tight, plan at least one short stage midway rather than a non-stop run.
Which direction should you walk the Tour du Mont-Blanc?
The tour is very predominantly walked anticlockwise, the direction used in guidebooks: it's the smoother waymarked direction, and the one where you climb the Trè-le-Champ ladders rather than descend them. Going clockwise, you meet the crowd head-on instead of following it, which has its charm if you're chasing some quiet, but you descend the equipped sections, which is less comfortable if heights aren't your thing. The number of days doesn't change either way. The detail of exposed sections by direction is in our article on the TMB for those afraid of heights.
