How to enter

Official ballot: most Asian city marathons take entries through a ballot on the official site, often open for only a few weeks.
Overseas runner channels: some races set aside overseas places or require a proof-of-time (e.g. sub-5:00 marathon).
Charity / tour places: if the ballot misses, watch for charity entries or official tour packages.

Notes for Hong Kong runners

Time zone: 1 hour ahead of Hong Kong. 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.
