Your preparation check

The calendar-listed date and distance shape this generic plan. Verify the date before committing; vertical targets stay blank until course elevation is verified.

Race week is already here

There is not enough time to create fitness safely before this edition.

Do not cram missed training. Prioritize recovery and decide whether starting is appropriate based on your existing preparation.

Default starting point: 35 stable km/week, longest recent outing 18 km, 4 running days/week, aiming to finish well.

No connected training history is used. Unanswered details remain conservative assumptions.
