Kettle Moraine

The Kettle Moraine race returns to Lagrange, Wisconsin on June 13th through the 14th of 2026, offering runners a diverse array of distances to choose from in one of the region's most anticipated annual events. Nestled along the picturesque trails and rural roads that wind through the heart of Kettle Moraine State Forest, this event has become synonymous with endurance running excellence.
The race unfolds against a backdrop of Wisconsin’s lush greenery and serene landscapes during late spring when wildflowers dot the forest floor and birdsong fills the air at dawn. The early morning mist clings to the trails like an ethereal veil before dissipating into brilliant sunshine, creating a magical atmosphere for runners as they embark on their journey through miles of natural beauty. As day progresses, participants are treated to the vibrant hues of late spring foliage interspersed with stretches where towering pines cast deep shadows over the path.
Kettle Moraine has been an integral part of the running community in Wisconsin since its inception, fostering camaraderie and pushing runners beyond their perceived limits through a challenging but rewarding course. Over the years, it has grown from a small local event to attract participants from across the country and even internationally. Each year sees hundreds more enthusiasts join the ranks of those who have come before them, building upon traditions that include awards ceremonies celebrating top finishers and recognizing exceptional performances in various categories.
The race course itself spans multiple terrains within Kettle Moraine State Forest, with routes ranging from a grueling 100-mile ultramarathon to shorter yet equally demanding distances such as the 50K. The varied landscapes encompass rugged trails that wind through dense woods, rolling hills dotted with wildflowers and grassy meadows. Runners can expect a mix of steep ascents and descents along sandy paths interspersed by stretches on smooth road surfaces.
Start/finish details are crucial for participants to know, as the event begins at N9084 County Road H in Lagrange where clear signage directs runners toward their respective race distances. The course profile includes significant elevation changes that challenge even seasoned athletes; aid stations are strategically placed every few miles along the route, offering hydration and snacks essential for sustaining energy levels throughout the day. Notable features of the trail include a scenic overlook midway through each distance where participants can pause to take in panoramic views before continuing their journey.
Given typical June weather conditions in Lagrange—characterized by average temperatures around 21°C with occasional breezes that keep humidity at about 68%—runners should prepare for warm yet comfortable running days. The chance of rain is relatively low, although participants may encounter a few scattered showers throughout the weekend if they are unlucky. Trails remain hard and dry underfoot thanks to recent spring conditions, providing firm footing despite potential mud patches in some areas.

The logistics of participating in Kettle Moraine involve navigating its unique lottery-based registration system which opens on December 1st and closes at midnight on December 30th for the main draw.
