Event Detail
The 19th Siriraj Walk and Run (ศิริราช เดิน-วิ่ง ครั้งที่ 19) is scheduled for Sunday 2 May 2027 in Bangkok. The long-running Siriraj event returns to the Chao Phraya River-side Siriraj hospital precinct in Bangkok Noi. Its organiser-linked announcement identifies Siriraj Piyamaharajkarun Hospital as the event venue.
2027 distances
- 21.1 km: half marathon.
- 11 km: mini-marathon category. This is an 11K event, not a conventional 10K.
- 5.5 km: fun run. The calendar's 5K filter is an approximation; the advertised course length is 5.5 km, not 5.0 km.
The 2027 date and these distances are confirmed on the current-edition event listing linked to the organiser's official announcement. The event is separate from the 18th Siriraj Walk and Run staged in May 2026.
Important information for runners
The final flag-off times, course maps, registration fees, ticket availability and race-pack collection arrangements have not been independently confirmed for this edition. The date is confirmed, but no arbitrary start time has been assigned. Consult the Siriraj Walk and Run organiser's Facebook page for the current booking instructions and subsequent official notices. Do not assume the previous year's rules or prices apply. The map points to the named hospital precinct and is not a verified start arch.
