Weeks on the same pack, repacked daily: why less really is more on a pilgrimage, and how to get your load under the 10 percent rule.
The honest answer first: your pilgrim backpack shouldn't weigh more than about 10% of your body weight — at 70 kg body weight, that's roughly 7 kg. That's noticeably less than you'd instinctively pack for a multi-week trip. The reason: unlike ultralight mountain trekking (see our dedicated Wandern guide), where you're self-sufficient for days, on a pilgrimage you carry your pack every single day for weeks — every extra kilo isn't paid once, it's paid twenty times over.
The 10% rule of thumb originally comes from 1950s US military studies on young, trained soldiers — not exactly representative of you. A more recent model shows: lighter people can carry proportionally more, heavier people proportionally less — the rule is a starting point, not a law. What holds for everyone: less weight demonstrably means less load on knees, shins, and the soles of your feet — exactly the spots that give out first on a week-long Camino.
Train Smart. Play Hard. here means: the smartest move isn't packing more, it's being brave enough to leave things out.
Take your body weight times 0.10 as a rough guideline — that's your pack's target weight without the day's water and food. Weigh your fully packed bag on a kitchen scale before you leave. The number doesn't lie; your gut feeling does.
You wear one set of hiking clothes; you wash the other each evening at the hostel and wear it dried the next day, tied to your pack. No third set "just in case" — every extra piece of clothing is weight you carry 20 times, not once.
What goes in first: spare socks and the blister kit. What goes in last and usually gets cut anyway: the third book, the extra camera, the "just for emergencies" pillow.
Almost every hostel has a washing machine, or at least a sink. Plan your packing list around that cycle, not around "enough for the whole trip". This is the biggest weight difference from classic multi-day backcountry trekking without infrastructure.
At least two test hikes of 15+ km with the pack actually loaded — not empty. Whatever presses or chafes on the test hike becomes a real injury by day 12.
An overloaded pack isn't dramatic on the Camino, but it's the most common silent trigger for overuse injuries in the shoulders, back, and above all the feet — exactly the injuries that actually end a Camino (own guide on that). If your pack is pressing, don't push through — reduce weight or arrange transport by the next rest day at the latest.
Set a hard limit before you pack — say, "7 kg max" — then pack backwards: mandatory items first (documents, foot care, rain protection), then everything else only if there's budget left. This flips the usual logic and stops "just a bit more" from adding up to 12 kg.
A good rule of thumb is around 10% of your body weight — at 70 kg, roughly 7 kg without the day's food and water. Lighter people can carry proportionally more, heavier people somewhat less.
Practically daily — almost every hostel offers laundry facilities. That's exactly why two sets of clothes are plenty, instead of packing for the whole trip.
No special model needed — a well-fitting 30–40 l hiking pack with a hip belt is enough. More important than the brand: it should weigh under 1.5 kg empty and be tested with full weight before the trip.
Then luggage transport is a legitimate option, not a sign of weakness — for a few euros per stage, your bag gets sent ahead. More in the luggage logistics guide.
