Day availability + notes

What it's for

Per-day metadata that isn't a workout: travel, illness, race day, or just a quick note ("flying to BCN 6am").

How to set

• Coach right-clicks empty space in a day cell on the coach calendar. The "Day options" modal opens.
• Premium athlete can do the same on their own calendar.

Options

• Available (default — clears any prior entry from the day)
• Limited time (yellow badge — partial training window)
• Unavailable (red badge — travel, work, family)
• Sick / injured (red badge — alert for the coach)
• Race day (orange badge — overlap with the race chip is OK, the chip stays a separate first-class anchor)

The optional Note field is a short free-form text (max 1000 chars) that renders as italic text under the badge. Hover the badge to see the note in a tooltip.

How it interacts with workouts

Availability doesn't auto-cancel workouts. A coach can still drop a workout on an "unavailable" day. The badge is a signal, not a lock. The Phase-4 advisory panel does take availability into account when recommending intensity.
