Your whole schedule in four parts: your goal, your build-up, the calendar with a status per session, and your settings. You build your new week on Sunday.
Training has four parts; switch at the top with Goal · Build-up · Schedule · Settings (each its own address, so you can link straight to one).
Below the Schedule you'll find last Sunday's debrief (Body, Energy, Time, Load) with a link to the full debrief screen.
Tap a session for details. Move weeks with the arrows. You build your new week on Sunday — looking back, checking in and confirming your proposal happens there, no longer on Training.
It got its own screen: Sunday (`/trainen/zondag`). Your look-back, your check-in and your new-week proposal live there together. On Training you only see a short summary of it.
The day passed without an activity and without Done. Your coach recalculates; there is no penalty and no score that punishes you.
From your own numbers: swim speed, bike speed, run pace and your longest sessions. It is a band of a few percent, not a promise.
