Adaptive race preparation for self-coached athletes, built by people who race it themselves. Here is why HYREN exists and how it decides.
Static plans break when the athlete changes.
A programme written on Monday cannot see what changed by Thursday. HYREN began with its founder's own training interruption — an ordinary athlete's problem, turned into a product brief. It is a training problem, not a medical claim.
One engine turns today's context into today's session.
Readiness, load, race context
From what you logged and how it felt — never from a device you did not connect.
Deterministic safety and progression rules
Bounded choices, with the constraints visible rather than implied.
One session that fits today
Not a library to search. The session, and the reason it is that session.
Completion and feedback update the state
What you did — and skipped — is what the next decision is made from.
The core decision stays explainable. AI can help build and narrate the experience; it does not invent the training decision. Why you can ask HYREN "why this session?" and get a real answer
The working product already closes the loop.
Readiness
Your own check-ins and sessions, scored into the number the day is built from.
Adaptive session
Re-scored against your race date and your recent training, every week.
Recovery
A five-day projection, and training that works around what hurts.
Library and state
The whole race — every station, plus the simulations — and your history behind it.
Deterministic core
Readiness, load and progression decisions you can trace back to a rule.
Longitudinal state
What you planned, what you completed, and what you reported about it.
Safety gates
Your constraints and recovery signals bound what the engine is allowed to ask of you.
Feedback flywheel
Observed decisions sharpen the rules, the test coverage and the explanations.
From an injury-led insight to an approved external beta in four months.
The brief
A training interruption scoped into an adaptive training product.
A working beta
Readiness, training, recovery and the Library, closing the loop end to end.
External beta
Approved by Apple's beta review, and in the hands of testers.
A public iOS launch is the next step, and it is subject to App Store submission and Apple's review — so we will say it has happened when it has.
Built by people who train on what they ship.

The guardrails we hold ourselves to.
No medical claims
Readiness informs training choices. HYREN does not diagnose, treat or prevent injury, and it is not a medical device. Terms § 5
Consent, and the minimum
Health data is recorded only because you chose to record it, under explicit consent, and none of it is required to use HYREN. Privacy § 6
Explainable decisions
Rule-bounded recommendations, visible constraints, and safety gates you can see rather than infer.
Your data is yours
No sale, no ads, no third-party trackers. Export and delete are buttons in the app, and they are always free. Privacy § 3.6
No implied partnership
HYROX® belongs to its owner. HYREN is independent, and any brand or ranking use would require written rights.
