How to enter

Public ballot: register during the published window; results usually arrive months later, and winners must pay by a deadline (unpaid places are released).
Qualifying time: run inside the qualifying window and submit official proof that meets your age-group standard.
Charity places: fundraise for an official charity partner — limited, usually first-come, and one of the most reliable routes.
Official tour operators: guaranteed-entry packages; pricier but the highest certainty.

Notes for Hong Kong runners

Time zone: 13–14 hours behind 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.
