Chiayi City Ponds International Half Marathon
Race Day Weather
Warm start, high humidity
A warm 75°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. High humidity (84%) will make it harder to cool down through sweat — increase fluid intake accordingly.
