Four questions come up in every Camino planning thread before anyone has picked a date: how many days do I actually need, where do I start and still earn the Compostela, what is this going to cost, and how long does a 25 km stage really take once the hills and the pack get involved. I asked all four before I left, and depending which forum answered that week, got a different number each time. The real arithmetic behind all of them is calmer than the forums make it sound — here it is, plainly, with the tools that run it on your own numbers rather than the internet’s average.
The Camino is not a race, and none of the four questions below has a single right answer — they only have an answer for the days, legs, and budget you actually bring. What follows is the arithmetic behind each one, and, at the end, the honest asterisk that none of them shows you until you line all four up together.
How many days does it actually take
The Camino Francés is 770 km, Saint-Jean-Pied-de-Port to Santiago de Compostela. The classic guidebook breakdown lays it out in 33 stages — an average of 23 km a day — and that number gets quoted as if it were the itinerary. Treat it as a floor instead: it assumes you walk every one of those 33 days back to back, on fresh legs, with no day off, which is rarely how a month on foot actually goes.
- 20 km a day — 39 days of walking
- 25 km a day — 31 days of walking
- 30 km a day — 26 days of walking
That is walking days only. Add a rest day every 5 to 7 walking days — worth scheduling in a town you actually want to linger in, rather than losing one to sore feet later — and most first-timers land at 32 to 38 days elapsed, not the 33 printed on the cover. Run your own pace through the Camino days calculator; I go through the week-by-week arithmetic in full, including why a marathon PB tells you almost nothing about your Camino pace, in how many days you actually need for the Camino Francés.
The route question hiding inside the days question
Most planning threads assume the Francés and then argue about pace, but the route itself is the bigger lever if your days are limited. The Camino Portugués from Porto is only about 240 km — at a steady 25 km a day that is roughly eleven walking days, which fits an ordinary two-week holiday with rest days to spare. It is the one classic route you can walk start to finish rather than join partway along. The Francés (770 km) and the Norte (822 km) do not fit a fortnight at any sane daily distance, so on those the honest question is not whether you qualify but where you start.
Where to start and still earn the Compostela
You do not have to walk the whole 770 km to get the certificate. The pilgrim office in Santiago issues the Compostela to anyone who completes the final 100 km on foot (200 km by bicycle), which is why Sarria — roughly five to six walking days out on the Francés — is the most-booked starting point on the entire route, ahead of Saint-Jean-Pied-de-Port itself. Starting from León cuts the walk to about two weeks; from Sarria, to about a week. None of those is a lesser Camino. It is a different answer to how many days you actually have, and the Camino days calculator will show you where each route lands for your own budget of time.
What it costs, in one paragraph
Budget €25 to €40 a day sleeping in municipal albergues and eating the pilgrim menu, or €55 to €85 once you trade up to private albergues and restaurant dinners — hotels push past €100. Multiplied across the 33 classic Francés stages, the walk itself runs roughly €760 to €1,320 on the cheap end or €1,800 to €2,800 in comfort, plus a one-off €100–300 gear buffer if you are starting from nothing and €30–80 to reach your starting town. The usual movers between those two bands are a private room over a dorm bunk, a bag-transfer day, and eating in the square right by the cathedral instead of two streets back — I go through where the money actually goes, habit by habit, in what the Camino costs per day, honestly. Put your own sleeping and eating style into the Camino budget calculator for a number that is yours rather than the average pilgrim’s.
How long a 25 km stage really takes
Flat-map arithmetic lies. At a steady 5 km/h, 25 km is five hours — the number most people plan a day around, and the number that is quietly wrong by the time the second hill shows up. Naismith’s rule, the 1892 estimate that still holds up, adds one minute for every 10 m of ascent on top of the flat-ground hour-per-5-km, plus a flat 10% for a loaded pack. A 25 km stage with 300 m of climb — an ordinary Camino day, not an outlier — comes out closer to five and a half hours of pure walking, and six to seven hours door to door once the coffee stop, the photo stop, and the ten minutes to get your boots back on are counted in. Put your own distance and the day’s ascent into the walking time calculator before committing to a daily distance on the stage planner — the map’s number and the day’s number are rarely the same one.
It is worth knowing which day is going to charge you the most for this. The hardest single stage on the whole Francés is day one — the Pyrenees crossing out of Saint-Jean — and it is also the day most first-timers most overestimate the rest of the walk by, because adrenaline is still doing the work that Naismith’s rule will start billing for honestly by day five. Whatever daily distance feels manageable on that first climb, plan the following weeks around week two, not around day one.
What actually earns its place in the pack
The old pilgrim guideline is to carry no more than about 10% of your body weight, which for most people rules out roughly half of what a gear list online will try to sell them. Season and where you are sleeping change the specifics — a liner instead of a full sleeping bag from late spring to early autumn in albergues, none of it at all in hotels — but the 10% ceiling is the number that actually matters, because every kilo over it shows up in your knees on the descents, not in how prepared you felt at the packing stage. The Camino packing list builds the season- and sleeping-style-specific version so you are not guessing at the margin.
The asterisk none of the four numbers shows on its own
The gear buffer and the transport cost in the budget section — roughly €130 to €380 combined — are one-offs. Spread across a full month from Saint-Jean-Pied-de-Port, that is a rounding error on the daily average. Spread across a one-week walk from Sarria, the same fixed euros land on a fifth as many days, so a short Camino’s honest per-day figure runs noticeably above the ranges quoted for the walk itself, even though the total is far smaller. Nobody budgeting a week-long Camino off a daily rate meant for a month-long one sees that coming, and it is the single most common way a short trip’s budget quietly comes up short in the first two days rather than the last.
Turning four numbers into an itinerary
None of the four numbers above mean much until they sit on a calendar next to each other — the days you have, the stages that fit your legs and the day’s ascent, the rest days you actually chose, and the budget that survives contact with week two. The Camino stage planner is where that happens: pick a route and a daily distance and it lays the whole thing out in real stage towns, in order, flags the days that cannot be shortened, and slots a rest day in every 5 to 7 days so you are not deciding that in Galicia with sore feet. Start there, or start with the Camino planning guide if you have not picked a route yet.
I planned mine with four browser tabs open and a spreadsheet that argued with itself for a week before any of these numbers agreed with each other. It does not need to take that long — the arithmetic is fixed, the tools run it in seconds, and the only genuinely hard question left is which stage town is worth losing a rest day to. And when the walk is done, Skoma turns the stages and the photos into a page-a-day book, Santiago as the last page rather than a folder of photos you meant to do something with eventually.
