Comfortable temps, big temp swing

Mild 58°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 73°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 77% is worth noting for effort level, especially in later miles.

About the Wausau Half Marathon

The Wausau Marathon's half marathon is a USATF-certified 13.1-mile course that starts and finishes in Marathon Park. It crosses the Wisconsin River to the north end of the Riverlife trail, returns south along River Drive and the southern part of the trail, then climbs through the Marathon County Sports Complex, the hilliest stretch of the route. Runners cross the river again on the Thomas Street bridge, join the marathon course on 17th Avenue and finish with a downhill run on Stewart Avenue into the park.
