Should you go?
A rare chance to run, or watch, a major marathon through central Bangkok's landmark old-town streets, with a clearly published date and registration open well in advance.
Good for: Runners who plan months ahead — registration is required and closes 31 October 2026
Think twice if: You are deciding last-minute — entry is by advance registration, not turn-up-on-the-day
Planning note: Start areas differ by distance (Sanam Luang vs MBK Center) — confirm yours before race weekend

Decision note: Only for runners who register in advance — entry closes 31 October 2026 and start points differ by distance.
