Korat Half Marathon
Korat Half Marathon race day weather
Warm start, rain likely, high humidity
A warm 74°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Light winds shouldn't be a major factor for pacing. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. High humidity (87%) will make it harder to cool down through sweat — increase fluid intake accordingly.

About the Korat Half Marathon
The Korat Marathon's half marathon covers 21.1 kilometers through Nakhon Ratchasima, starting at the Thao Suranaree Monument in the city center and finishing at Bung Ta Lua Water Park. It is a point-to-point course on roads closed to traffic, and the 4:00 AM start keeps most of the field out of the worst of the tropical daytime heat. It shares its start and finish venues with the full marathon.
