Springfield Half Marathon race day weather
Cold start — layer up, warming through the race
Runners will start in chilly 36°F conditions — dress in layers for the corral and plan to shed early. Temperatures rising to 50°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.

About the Springfield Half Marathon
The Harvest Wind Half Marathon is a USATF-certified 13.1-mile loop that starts and finishes at Danenberger Family Vineyards in New Berlin, west of Springfield. The course heads west on Irish Road, winds through the neighborhood streets around Rhea Park and out Clevenger Road to a half-mile turnaround, then returns by way of Base Road to the vineyard. It is the same loop the marathon runs twice, on flat Central Illinois farmland and village roads.
