Two weeks asks for the same list a weekend does
I have bags for a weekend. Do I need more for two weeks?
A rider whose bags worked for a weekend wants to know whether two weeks needs more of them. That is a buying decision, and it has a checkable form: hold one ride still, move only the answer about how many nights you are out, and count what changes on the list the planner produces.
20requirement lines asked for, at one night and at ten alike
Nothing is added by the longest answer and nothing is dropped by the shortest. The ride held still is wild camping on gravel and tracks, cold but not freezing, rain probably, cooking, a few trips behind the rider, a shop passed every day, and around 40 km as the longest stretch without water. Only the nights answer moves, and it moves through the four values the interview offers rather than along a slider.
The one line that reads the answer
| Your answer | Nights | What the battery line asks for |
|---|---|---|
| One night | 1 | enough for 1 night without mains |
| A weekend | 2 | enough for 2 nights without mains |
| A long weekend | 4 | enough for 4 nights without mains |
| A week or more | 10 | enough for 10 nights without mains |
Seven other requirement lines carry a spec of their own, and not one of them moves across the four answers. Two figures worth naming are held still by different questions entirely: water capacity stays at 3500 ml, which the longest stretch without water decides, and the sleeping bag rating asked for stays at 3 °C, which the night low decides. Trip length reaches neither.
Where the length does land
Food is the requirement that grows, and it does not grow with nights alone. The count reads two answers at once — how many nights you are out, and how often you pass a shop — so the length of the trip cannot state it by itself.
| Your answer | Shop every day | Shop every couple of days | Shops rarely, or not at all |
|---|---|---|---|
| One night | 1 | 1 | 2 |
| A weekend | 1 | 2 | 3 |
| A long weekend | 1 | 2 | 5 |
| A week or more | 1 | 2 | 11 |
The first column is flat: a rider who passes a shop every day carries the same food on the tenth night as on the first. The middle column rises once and then stops. Only the last column tracks the trip. So the honest answer to whether two weeks needs more capacity than a weekend is that it turns on the resupply rather than on the calendar, and that on this list food is the only place the difference shows up at all.
What this cannot tell you
Whether your bags hold it. The planner holds no volume for a day's food, no mass for a battery, and no price or maker for either, because none of those were measured — it produces requirement lines and the specs attached to them, and the litres are yours to check against your own bags. The sweep is also one ride: change how cold the nights get or how far apart the water is and other lines move, but they move for those answers, not for the length. And a requirement line is not a quantity of kit, so the same line can mean a fuller bag without ever becoming a second one.
Every claim above, and how it is known
- DERIVEDAt every one of the four nights answers the planner asks for the same 20 requirement lines.
- DERIVEDNo requirement line is added by the longest nights answer, and none is dropped by the shortest.
- DERIVEDThe four nights answers the interview offers are 1, 2, 4 and 10 nights.
- DERIVEDOne spec line moves with the nights answer: the battery pack, which asks for enough for 1, 2, 4 or 10 nights without mains.
- DERIVEDSeven other requirement lines carry a spec, and none of them moves across the four nights answers.
- DERIVEDWater capacity stays at 3500 ml and the sleeping bag rating asked for stays at 3 °C across all four nights answers, because other answers decide them.
- DERIVEDWith a shop passed every day, the food requirement is 1 day at all four nights answers.
- DERIVEDWith a shop every couple of days, the food requirement is 1 day at one night and 2 days at a weekend, a long weekend and a week or more.
- DERIVEDWith shops rarely or not at all, the food requirement is 2 days at one night, 3 at a weekend, 5 at a long weekend and 11 at a week or more.
Other notes worked the same way
- A frame size is a name; these are the measurements that decide
Swap one measurement of a medium frame for another frame's value: the top and down tube edges move verdicts, and the triangle's volume moves none.
- Where the planner picks for you, and where it will not
Twelve of the twenty-six requirements offer a choice. The planner names one only when an answer makes another wrong, and in one it never does.
- Tight means two different boundaries, and only one is a measurement
The engine holds most clearances to 8 mm of measurement tolerance and the tyre gap to 15 mm, so a 12 mm gap can still come back Tight.
Every figure here came out of the same rules that answer the interview, so it moves when they do. Yours differ wherever your answers differ.
