Prepare for a unique endurance test at the Icebox 480/240, a timed running challenge set for November 7, 2026, in the scenic Whitetail Ridge of River Falls, Wisconsin. Offering both 8-hour and 4-hour challenges, this event invites runners to accumulate as many miles as possible on its beautiful single-track course. Typical race day conditions for early November present crisp air with highs around 46°F and lows near 26°F, alongside a minimal 6% chance of precipitation, creating an invigorating atmosphere for trail running.
The Icebox 480/240 takes place on picturesque mountain bike trails, featuring a main loop of approximately 5 miles per circuit. Runners can expect a dynamic course characterized by a pleasant mix of mild elevation changes, rocky and rooted sections, and quick rollers, rather than prolonged climbs. This "nice run through the woods" offers a chance to explore the park's beautiful trails. A robust aid station located at the start/finish area keeps participants fueled with typical snacks and, as the day progresses, heartier options like chicken noodle soup, quesadillas, and mashed potatoes. As a cupless event, runners are encouraged to bring their own hydration containers for refills.
What truly sets the Icebox 480/240 apart is its low-key, community-focused approach and flexible start times between 6:00 AM and 8:00 AM, allowing runners to find their individual pace on the single-track trails without the rush of a group start. In the final hour of either challenge, participants have the exciting option to switch to a shorter 1.05-mile loop to push their limits further. Having started nearly a decade ago, this event has a reputation as a favorite for many, welcoming new ultramarathoners and seasoned veterans alike to test their endurance in a supportive environment.
