About This Race

The Icebox 480/240 brings a distinctive timed format to Missouri's trail running scene, challenging participants to accumulate maximum mileage within strict time limits. Runners choose between 4-hour or 8-hour challenges on a roughly 5-mile single-track loop course in Wildwood's scenic parkland. The flexible start window between 6:00 and 8:00 AM accommodates different pacing strategies and personal preferences. What sets this event apart is its strategic final hour, when participants can switch to a shorter 1.05-mile loop to maximize their total distance. This format rewards both endurance and tactical thinking, as runners must balance energy conservation with the opportunity to add extra miles when the course shortens. The November timing provides crisp fall conditions that justify the "Icebox" name while avoiding Missouri's summer heat. With over a decade of history dating back to 2013, this St. Croix Running Company event has established itself as a reliable test of stamina and strategy. The accessible entry fees and welcoming atmosphere make it suitable for runners exploring timed formats for the first time, while the 8-hour option provides a serious endurance challenge for experienced ultra runners.

The primary course follows approximately 5 miles of single-track trails through Wildwood's parkland, offering a manageable loop distance that allows runners to gauge their progress and adjust strategy throughout the event. The single-track terrain provides technical interest without overwhelming difficulty, making it accessible to various skill levels while still demanding attention and proper trail running technique.

During the final hour of each event, participants can transition to a shorter 1.05-mile loop, creating opportunities for strategic mileage accumulation when fatigue might otherwise limit distance on the longer circuit. This dual-loop format adds a tactical element that distinguishes the Icebox from standard timed events.
