General full-marathon entry and the first-marathon completion-support allocation are closed. The organizer still advertises separate resident-priority, hometown-tax, premium and 5K/junior 3K/family 1K application routes through 4 December 2026, subject to each allocation's eligibility and capacity. Use the organizer's category selector, not the closed general-full link. The full marathon has a seven-hour limit; all categories belong to this one dated edition.
