Chombueng Half Marathon
Race Day Weather
Warm start, warming through the race
A warm 71°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temperatures rising to 81°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 78% is worth noting for effort level, especially in later miles.
