Ann Arbor Half Marathon
Race Day Weather
Comfortable temps, warming through the race
Mild 54°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 69°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 70% is worth noting for effort level, especially in later miles.

Race Info
The Ann Arbor Half Marathon covers 13.1 miles on the first loop of the marathon course, starting and finishing in downtown Ann Arbor. It runs east through the University of Michigan campus, drops to the Huron River and the Gallup Park area, then returns past Mitchell Field, the medical campus and Nichols Arboretum. The course is rolling rather than flat, with its low ground along the river and its high ground on campus, near miles 2 to 3 and again around mile 11.
