Shake off the winter chill and welcome the spring running season at the First Call Half Marathon, 10K, and 5K, set for Sunday, March 22, 2026, in Waukesha, WI. This event, a key fixture in the popular Chilly Willy Winter Run Series, is renowned for its "lightning-fast" and "faster than flat" courses, making it an ideal race to set a personal best or kickstart your year. Runners will navigate the scenic Glacial Drumlin and Fox River Trails, experiencing minimal elevation change as they journey through wetlands, forests, and along the Fox River. The Half Marathon course, consisting of three loops, guides participants along both trails, while the 5K utilizes the Fox River Trail and the 10K takes to the Glacial Drumlin Trail, all starting and finishing at the E.B. Shurts Building within the Fox River Sanctuary.

Participants can expect robust support on the course with two aid stations, conveniently passed twice, fully stocked with water, sports drinks, and energy gels. Restrooms are available at both the start/finish area and along the route for added convenience. Unique to the First Call, all finishers will proudly receive a distinctive "woodle" (wooden medal) from Ridgeway Woodworks, with custom woodles awarded to the top three male and female finishers in 5-year age groups. For those aiming for an early start on the Half Marathon, an option is available to provide extra time on the course, though early starters are not eligible for age group or series awards.

Typical race day conditions in late March in Waukesha feature highs around 46F and lows around 27F, with a modest 11% chance of precipitation, providing cool and favorable running weather. Beyond the traditional distances, the First Call also offers 1K Kiddo's Race and Ruck divisions for both the 5K and 10K, ensuring an inclusive atmosphere for all ages and paces. Whether you're chasing a new PR or enjoying a refreshing early spring run, the First Call Half Marathon promises a well-organized and memorable experience to launch your 2026 racing calendar.
