Each phase has a job
Ask what the current block is protecting: durable aerobic work, race-specific quality, recovery, or sharpening. The answer tells you far more than whatever the block is called on the calendar.
We plan each phase around that answer. In an aerobic base block you'll see plenty of easy volume, with recovery days spaced out and labeled. When a race is close, every hard session is there for a stated reason.
Your week has to bend
A plan that assumes perfect sleep, perfect weather, no travel and a body that never complains breaks the first time real life turns up. When a session slides or gets easier, the intent of the block stays the same.
The links on this page go to Tri for the full race build, the experience overview for how the plan regenerates when your schedule changes, and the compare page if you're choosing between lanes.
Race-build changes need a visible plan.
Route, load, and schedule cues keep the guide connected to the plan controls athletes inspect next.
Health guidelines are a starting floor
Public health guidance is a good floor for staying active. A triathlon plan needs a lot more on top: balance across three sports, skill work, sport-specific intensity, and enough rest to absorb it.
We use those sources as a check on conservative principles. The training itself comes from parts of CorrCoach you can see: the calendar structure, regeneration when your week changes, readiness notes and lane-specific planning.
