n = 1 · single-subject experiment
Every athlete is a sample size of one
Training advice is written for populations. You are not a population. n1athlete works the other way round: one question, one protocol, run on one subject, measured properly, and written down in enough detail that you can run it on yours.
The protocols are published as documents, not courses. You buy one, you download it, you test it in training, and you decide whether it holds for you.
The library
Published protocols
Protocol 01
Race-Week Protocol
The last two weeks before a marathon or ultramarathon, written as a procedure: nutrition phasing, sleep structure, pre-race tracking and a power-calibrated warm-up. Built around preventing the gut problems that end races nobody was undertrained for.
Further protocols are published when they have been tested long enough to be worth publishing. There is no release schedule.
Why it is built this way
An honest sample size
The method is the product
What is for sale is a documented procedure, not a personality and not a transformation story. If the reasoning does not hold up, the protocol is not worth buying.
Sources are stated
Every claim that rests on published research is cited to a source you can find and read yourself. Where the research is thin or contested, the document says so rather than rounding it up into confidence.
n = 1 does not generalise
One subject is one subject. These protocols are a structured starting point to test on yourself, which is why every one of them is written to be trialled in training before it is used in a race.
