Lace up your trail shoes for the NK50k, a quintessential point-to-point journey through the breathtaking Northern Kettle Moraine Ice Age Trail in Greenbush, Wisconsin, on April 11, 2026. Offering both 50K and 25K distances, this "fun run" is renowned for its welcoming atmosphere, where the spirit of community triumphs over competition—no official results are posted, but an "Almost World Famous NK50k Finisher Sticker!" awaits those who conquer the course.

Runners will navigate a diverse and challenging landscape, from smooth, rolling ski trails to rocky, root-laden sections, including the highest point in the Northern Kettle Moraine State Forest. The scenic route winds through dense deciduous forests, under tall pines, and across open prairies, showcasing the unique geological features left by ancient glaciers. The 50K kicks off at the Ridge Road Trailhead, while 25K participants begin their adventure at Crooked Lake, with both distances culminating at the Greenbush Group Camp, where post-run refreshments and food await. Transportation is conveniently provided from the finish line to both start locations.

Expect a well-supported experience with aid stations strategically placed at mile 3.5 and mile 25 for 50K runners, in addition to water stops near backcountry shelters. These stations are stocked with typical ultra-fare, including water, sports drink, Coke, and Mt. Dew. Typical race day conditions in mid-April feature highs around 54°F and lows around 33°F with a 16% chance of precipitation, embracing the lively spirit of spring in Wisconsin—which, as race organizers playfully note, "means it will most likely be snowing!" This unique blend of challenge, camaraderie, and quirky charm makes the NK50k a must-do for trail runners looking for an unforgettable experience.
