Welcome to the heart-pounding Icebug Birkie Trail Run 2026, an exhilarating adventure set in the enchanting landscapes of northwest Wisconsin. Organized by the American Birkebeiner Ski Foundation, this event invites trail runners to experience the beauty and challenge of the Birkie Trail, renowned for its rugged terrain, winding paths, and sweeping views of rolling hills.

Strambecco rates the Birkie Trail Run as one of the Best Trail Running Race Events in the Midwest and one of the Best Trail Running Race Events in Wisconsin. The event offers a wide range of race options, from a non-competitive Nordic Trek to the grueling USATF Mountain Ultra Trail Marathon Trail Championship, where top athletes from around the country gather to test their endurance and skill on challenging trails.

The Birkie Trail Run course consists of 80% ski trails and 20% singletrack trails. The ski trails are wide, ranging from 10 to 30 feet, mostly grass-covered, with some dirt paths. The glacial topography leads to numerous steep, short climbs (up to 50 feet) with 10-20% slopes, making for a challenging run with relentless ups and downs. The singletrack trails, designed for mountain biking, are intermediate-level and less steep, with winding paths and tight switchbacks.

Marathon (26.2 miles): This ultimate test of endurance takes runners through a rugged 26.2-mile course featuring both single-track and ski trails. The route showcases the beauty of Wisconsin’s forests and the thrilling challenge of climbing to the summit of Mt. Telemark, where breathtaking views await. The marathon starts at 7:30 a.m., and participants must be 16 years or older by September 23. Top finishers in the marathon will be awarded prize money, with the overall winners receiving $700 for 1st place, $500 for 2nd place, and $300 for 3rd place.

Half Marathon (13.1 miles): The half marathon offers a slightly shorter but demanding course. Runners will traverse 13.1 miles of scenic trails, weaving through lush forests, ski trails, and newly completed single-track routes.

Marathon Relay (26.2 miles total): The marathon relay is a team-based race in which groups of 3 or 6 participants split the 26.2-mile distance. Each runner completes part of the scenic 13.1-mile loop. Relay teams can exchange runners at five designated aid station locations.

Nordic Trek (9.5 miles): For a more leisurely, non-competitive experience, the Nordic Trek invites participants to enjoy the scenic beauty of the Birkie Trail at their own pace. This 9.5-mile course features wide, flowing paths designed for trekking, allowing participants to soak in the views from Mt. Telemark without the pressure of a race clock.

5K Run/Walk (3.1 miles): This scenic route through the Birkie Trail area is a great introduction to trail running for beginners or those looking for a lighter challenge.

Awards will be given to the top three male and female runners in each age group, and custom trophies and Icebug running shoes will be awarded to the overall male and female winners. The weekend also includes fun post-race celebrations, including snacks, drinks, and a complimentary Earth Rider Beer or soda at the finish line.

For those seeking inspiration before race day, the event kicks off with the Trail Running Film Festival on Friday night. This festival features captivating stories from the world of trail running, making it the perfect way to prepare for your own adventure.
