Khon Kaen International Half Marathon
Race Day Weather
Warm start
Starting at 67°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. Moderate humidity at 79% is worth noting for effort level, especially in later miles.
