First Call Half Marathon
Race Day Weather
Cold start — layer up
Runners will start in chilly 36°F conditions — dress in layers for the corral and plan to shed early. Temperatures rising to 44°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

Race Info
The First Call Half Marathon starts and finishes at the E.B. Shurts Building in Waukesha's Fox River Sanctuary, running out-and-back along the Glacial Drumlin State Trail with a return leg on the Fox River Trail. First Call closes out Silver Circle Sports Events' Chilly Willy Winter Run Series each March, paired with a companion Last Call race the previous December. Results are on file back to at least 2018, alongside 5K and 10K options and a walker/ruck division.
