Comfortable temps, warming through the race, moderate wind

Starting at 64°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temperatures rising to 79°F through the course will gradually increase perceived effort in the second half. Moderate winds around 16mph may affect pacing on open sections of the course.

Race Info

The Half Marathon starts and finishes at Half Day Forest Preserve in Vernon Hills, Illinois. Runners go a short way south on the Des Plaines River Trail, return through the start area and then head north to a turnaround near the Route 60 canoe launch before coming back to the finish. The crushed limestone path is flat and wide, and the course has no road crossings, so the whole distance is run on the trail.
