Comlara 12 Hour Sunrise-Sunset, 6 Hour, 3 Hour and Hour of Power Trail Run
Lake Run Club, established in 1982, is hosting a series of timed trail events at Comlara in Hudson, Illinois. The course is a measured 4.5 mile loop that was checked with multiple GPS devices for 2026. For 2026 the course is slightly longer than prior years, with more single track and fewer open grassy fire road sections.
Timed formats use a repeating one-hour lap structure: runners must complete each 4.5 mile loop within the hour to continue; runners not back at the top of the hour are removed from that timed competition. The 12 hour format is run as a last person standing competition with repeated hourly starts. The 6 hour and 3 hour formats follow the same hourly restart method. A one hour option is offered for a single loop with no awards. An open-course option allows runners to complete loops at their own pace during the course window; a self service loop counter board will be available. A relay team competition accepts teams of three who hand off each lap and the team with the most laps wins.
Other event notes: packet pickup is available the day before the event, race day registration is available online only at a higher cost, weather pauses are possible for lightning or thunderstorms, and partial proceeds will go to Comlara parks.
