The real cost of running January's training week through your sending season is this: you turn up to perfect conditions carrying a training block's fatigue. The rock is dry, the holds are cold, and you're still paying for last Wednesday's volume.
If you climb outside, you have a competition date too. It isn't printed on a calendar. It's written in weather.
The calendar you already have
Everyone who climbs outdoors has months where conditions are good and months where they aren't. Too hot, too humid, too wet, too cold, too dark after work. Whatever your version is, some part of your year is when the sending happens and some part is when it plainly doesn't.
That's a season, and it means your year already has a structure whether or not your training acknowledges it. Keep running the same week in January that you run in your best month and you'll find out at the crag, not in the log.
Two modes, not twelve months of the same thing
You can describe most sensible outdoor training years with two modes. Not a phase chart with four colours. Two states, and the only thing that matters is knowing which one you're in.
Off-season: build. The stretch when conditions are useless anyway. This is when hard, fatiguing work is cheapest, because being tired costs you nothing you wanted. Heavier loading, more volume, the boring accessory work you never get around to, the positions your climbing doesn't cover. If you're going to feel wrecked on a Wednesday, this is the time of year to do it.
In season: maintain. Your good months. Training's job flips from building to not-losing, and not-losing is cheap. The performance days are the point and everything else exists to avoid costing you one. Our companion post on in-season maintenance takes this apart properly.
There's no peaking phase in the middle, no taper block, no sharpening period. Those exist in sports built around a date somebody else picked. Your season is a stretch of months, not a Saturday in April, and treating it as a single state you switch into is closer to how outdoor climbing actually works. The transition is real, but it's a transition between two things, not a third thing.
Everyone's version of these looks different. A person with one three-week trip a year and a person with a six-month sending season are running different shapes, and neither is doing it wrong.
What actually changes between modes
Three variables carry almost all of it, and each already has a post that owns the mechanics.
- Load and intensity. How heavy the hard sessions are, and how close to your limit you take them. Frequency follows load: heavier work needs more room around it, which is the argument in our frequency post.
- Volume. How much total work you're absorbing per week. This is the variable that carries the switch. Going into your season, volume is what comes down; the intensity is what you keep, which is the argument the maintenance post makes in detail.
- Proximity to your climbing days. Off season you can afford to train before you climb and let the climbing be sloppy. In season you can't, because the climbing is the point. Our session order post is the whole answer here: whatever you care about most gets fresh fingers, and in season that's the rock.
What does not change all year
- The log. Same columns, same conditions, twelve months a year. It's the only thing that tells you whether the shape of your year is working, and our log post covers reading a trend past the noise.
- The test position. Whatever edge and grip you standardised on, keep it. A number measured in January and a number measured in October only mean something together if nothing else moved. See the testing post.
- Deloads. They aren't a build-season luxury. Our deload post makes the case that stalled numbers are often fatigue wearing a plateau's disguise, and that's at least as true in season as out of it.
No week counts, no invented calendar
There's no eight-week build and no twelve-week season here. The exact length of a block depends on the person, their training age, their recovery, and the shape of their year. A number invented to fill a calendar wouldn't travel. The two modes are described by what changes between them, which is the part that's actually portable.
Put the hard, fatiguing work where being tired is free, back the volume off when the good months arrive, and in season let training serve the climbing instead of competing with it.
The bottom line
Plenty of people never periodize and still get strong. They turned up for years and the volume accumulated. The catch is they also turned up to their sending months carrying whatever the last block left in their fingers. If those months matter to you, two modes is the whole system: build when conditions are useless, maintain when they are good, and keep the log and the test position constant so you can tell whether any of it worked. The weather already wrote the outline. You're only deciding whether to read it.
