Comfortable temps, warming through the race

Mild 53°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 65°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

About the ZombieRunner Halloween 10K

The ZombieRunner 10K follows the paved Coyote Creek Trail from Hellyer County Park, runs just past the Silver Creek aid station, then turns and returns to the same start and finish. The surface is asphalt, the course is relatively flat, and the route is marked with directional signage all the way. Runners who race in a Halloween costume can enter the day's costume contest.
