Wisconsin Trail Series

Embark on an invigorating trail adventure at the Wisconsin Trail Series Half Marathon, unfolding on April 10, 2026, in picturesque Oconomowoc, WI. This event, part of the larger Wisconsin Trail Assail Series, invites runners and walkers alike to explore the stunning natural beauty of Waukesha County and Wisconsin State Parks. Expect a course designed for enjoyment, featuring wide, well-marked trails that wind through varied terrain including woods, rolling hills, and scenic prairies. While some sections may offer a technical challenge, many trails are thoughtfully groomed with wood chips for a smoother experience, ensuring captivating views at every turn.

The Wisconsin Trail Series is renowned for its consistent organization and friendly atmosphere, backed by a "money-back guarantee" if you're not satisfied. As an environmentally conscious "cupless series," participants are encouraged to bring their own hydration systems to refill at two well-stocked aid stations offering water and Gatorade. Upon crossing the finish line, celebrate your accomplishment with a unique finisher "woodle" and refuel at the complimentary fresh fruit bar. With typical race day conditions seeing highs around 54F and lows near 34F, and only a 15% chance of precipitation, April promises ideal weather for hitting the trails.

Beyond the half marathon, the event is proudly walker-friendly and includes a free Kiddos 1K race, making it a fantastic experience for the whole family. An "All Access Pass" option even allows you to bypass packet pickup lines, getting you straight to the open field start and onto the scenic trails. Join fellow enthusiasts for a memorable run through Wisconsin's captivating landscapes.
