Icebox 480/240

Icebox 480/240 is a timed trail event held in River Falls, Wisconsin, on November 7, 2026. As the name suggests, you can run for 480 minutes (8 hours) or 240 minutes (4 hours), with both formats starting at 6:00 AM. Your result is simply the distance you cover before time runs out, which makes the race approachable and competitive at the same time.

Early November in Wisconsin lives up to the Icebox name, so cold-weather gear and a drop bag with dry layers are worth planning for. The 4-hour format suits runners who want a first long trail effort without a hard distance target, while the 8-hour is a solid alternative to a 50K or 50-mile race for anyone who prefers to run by feel. In training, build up to long runs of three to four hours and practice eating real food while moving, because the ability to keep fueling is what separates a strong afternoon from a long walk.
