Triathlify writes a real periodized program — base, build, peak — then quietly redrafts each week as your body and your calendar move. The plan you start with is never the plan you finish with.
Two short nights, a stressful Monday, a cold coming on — Triathlify reads the signal and quietly trims volume and intensity for the rest of the week. No skipped weeks. No falling off.
Sleep, HRV, stress signals, calendar conflicts, even the weather forecast — all feed the daily rewrite. Not "did you train?" but "what kind of week is it?"
Real base / build / peak structure with deliberate de-loads. Block lengths, threshold work, and brick days are sequenced to your race date — not generated by vibes.
Miss a swim? It tells you what that costs and what to prioritize. No "make-up" guilt sessions — just a recalculated path to your A-race.
Tell it Tuesday is a no-go. It plans around it — every week. Travel, kids, shift work — Triathlify treats your real life as the constraint, not noise.
Triathlify's plans are built on four-phase macrocycle theory — the same framework used by national federations and coaches like Joe Friel and Matt Dixon. The adaptive layer doesn't replace the structure. It defends it.
Aerobic capacity, technique, injury-proofing.
Threshold work, brick days, race-pace efforts.
Sharpen, simulate, freshen up. Volume drops, intensity stays.
Taper, fuel, rehearse transitions. Trust the work.

No. Triathlify works from heart rate and pace alone. If you have a power meter, it adds a third lens — sharper bike prescriptions and better fatigue tracking.
Built in. Two short sessions a week through Base and Build, dropped to one in Peak. You can swap our routines for your own; the plan accounts for the load either way.
Yes. Tell Triathlify the new race, the new date, and it rebuilds — keeping the fitness you already have and adjusting the path forward.
Yes — you can log sessions manually in under 10 seconds. RPE, duration, distance. The adaptive engine works on any of these signals.
Those are great tools for one sport, or for executing a coach's plan. Triathlify *writes* the plan, across all three sports, and rewrites it weekly without you asking.
Hit "I'm hurt." Triathlify rebuilds the week with cross-training and rehab-friendly sessions, then ramps you back when you clear it.
