About the Bangsaen21
Bangsaen21 is one of Southeast Asia's highest-profile stand-alone half marathons and carries World Athletics Platinum Label status. Its qualifying and returning-runner entry paths create a more performance-focused field than a typical mass-participation resort race.

The dedicated 21.1K road course runs around the Bangsaen area in Chon Buri, with the organizer publishing the route as a current map. Coastal exposure and tropical conditions make disciplined effort more important than assuming the quick field guarantees an easy personal best.
