How to enter

Official ballot / first-come: Hong Kong races mostly take entries by ballot or first-come-first-served, with some priority categories.
Charity / corporate places: several races offer charity or corporate-team entries — ask the organiser.
Team format: some trail events (e.g. Trailwalker) require a team entry, so assemble your team first.

Notes for Hong Kong runners

Time zone: same time zone (local race). Entry windows are published in local time — the Hong Kong equivalent may fall a day earlier or later, so have your account and payment ready the day before.
Register early: most races require a verified account before entries open, and opening-day traffic is heavy.
Places get released: unpaid entries are freed up, and some races run a supplementary ballot.
Avoid unofficial transfers: most races forbid bib transfers, and buyers risk disqualification.
