First Call 5K, 10K, & 1/2 Marathon

Spring in Wisconsin means shedding winter layers and lacing up for the First Call 5K, 10K & Half Marathon. Now in its 11th edition, this low-key season opener draws around 109 finishers—many of them repeats, with 21% returning each year. The course follows the lightning-fast paved trails of the Glacial Drumlin and Fox River, a route the organizers call “faster than flat.” It’s a simple out-and-back, ideal for shaking off the rust and chasing a respectable time.

The course is straightforward and not particularly scenic—just a paved trail winding through the Wisconsin landscape. Runners note it can be exposed and windy, but the flat, fast surface makes it a PR-friendly choice for those looking to start the year strong. The atmosphere is friendly and low-key, with a small, community-oriented crowd. Typical winning times hover around 74:38 for the half marathon, reflecting a field that’s competitive but welcoming.

Post-race, runners are treated to a nice spread of food, and finisher medals are crafted from pine—“woodles,” as they’re called. T-shirts are included, though sizing can be hit-or-miss (unisex regardless of request). For runners in the Milwaukee/Chicago area, it’s a convenient, no-frills way to dust off winter and signal the start of race season.
