About This Race
The CLE Trail Challenge takes runners through North Chagrin Reservation in the Cleveland Metroparks system, offering a loop-based format that puts choice in runners' hands. This northeastern Ohio race moved from its original marathon distance to a more flexible structure, allowing participants to tackle one, two, or three 10.5-mile loops based on their goals and race-day condition. The event emphasizes accessibility and enjoyment over rigid finishing requirements. Runners register for their intended distance but can adjust on race day without penalty, eliminating the possibility of DNFs. The course design prioritizes runnable terrain over technical challenge, making it suitable for runners testing longer distances or seeking a fast trail experience. The race maintains strong community ties through the CLE Trail Runners Facebook group, fostering a local running culture in the Cleveland area. Custom medals and trophies add a personal touch, while the straightforward loop format appeals to runners who prefer predictable aid station access and crew support opportunities.
The course consists of a 10.5-mile loop through North Chagrin Reservation's AB Williams Memorial Woods, designed for speed and accessibility rather than technical challenge. Runners encounter mostly dirt and crushed gravel bridle trails with approximately one mile of pavement per loop, creating a fast, runnable surface throughout most of the course.
Each loop features only two significant climbs, making elevation manageable across all distances. The relatively flat profile and well-maintained trail surfaces allow runners to focus on pacing and endurance rather than technical navigation, particularly appealing for those training for road ultras or seeking fast trail times.
