About This Race
OUTLAST Chicago presents a distinctive twist on trail endurance running with its unique six-hour format. Runners must complete a 5K loop every hour on the hour, with each lap serving as both challenge and checkpoint. The format creates a compelling tension between speed and sustainability, as runners who finish their lap early can rest until the next hourly start, while those who miss the cutoff are eliminated from the event. The race operates on a simple but unforgiving principle: complete all six rounds within the time limit to OUTLAST. This format attracts runners seeking something different from traditional trail races, where pacing strategy becomes critical. The hourly structure creates natural rest periods for efficient runners while maintaining pressure to stay within the cutoff times. Set in Palatine, Illinois, the event offers both single-day and weekend options, allowing runners to participate on Saturday, Sunday, or attempt both days for a true test of consistency and recovery. The flat terrain keeps the focus on endurance and pacing rather than technical skills, making it accessible to runners of varying experience levels who can maintain a steady 5K pace.
