Louisiana Half Marathon
Race Day Weather
Cool start — fast day potential, warming through the race
A cool 44°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 58°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 69% is worth noting for effort level, especially in later miles.

The Louisiana Half Marathon covers 13.1 miles on a USATF-certified course through Baton Rouge on the Sunday of race weekend. It starts downtown at A.Z. Young Park and shares its opening miles with the marathon, circling LSU's campus and University Lakes. The half then splits off from the marathon and heads back toward downtown, finishing on a run toward the State Capitol.
