Trivandrum Half Marathon
Trivandrum Half Marathon race day weather
Hot start, rain likely, high humidity
A warm 79°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. High humidity (83%) will make it harder to cool down through sweat — increase fluid intake accordingly.
