Chennai Half Marathon
Race Day Weather
Hot start, moderate wind
A warm 78°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Moderate winds around 12mph may affect pacing on open sections of the course. Moderate humidity at 72% is worth noting for effort level, especially in later miles.
