Siem Reap Half Marathon

Launched in 2015, the Siem Reap Half Marathon is one of the newer races on the circuit. Despite its youth, it has quickly built a reputation in Siem Reap, attracting runners drawn to its flat roads and scenic routes and the energy of an event still finding its identity.

Runners come to the Siem Reap Half Marathon for one reason: personal bests. The flat, fast course through Siem Reap has a reputation as a PB factory, with the roads seemingly designed to keep your pace honest and your splits consistent from start to finish.

With average race-day temperatures around 32°C, the Siem Reap Half Marathon is as much a battle against heat as against distance. DNF rates climb when the sun is out, and smart pacing in Siem Reap's warmth separates experienced runners from those who went out too hard and paid for it.
