Lock the entry window first
Ballots, qualifying systems and first-come entry require very different preparation.

Use this calendar
Plan around the next decision, not just the next destination.
Then place training blocks
Use the gaps between race dates to judge whether two targets can coexist in one season.
Wait when the organizer has not published
RaceZip does not manufacture a 2027 SEO page from “it is usually on this Sunday.”
