10 miles
The 10-mile route navigates Frontenac State Park's mixed terrain, combining prairie sections where runners can maintain rhythm with single-track trails that demand technical attention. The course moves between grassland meadows and forested ravines, with the winding trails through wooded sections requiring careful footing. The terrain includes the characteristic features of Mississippi River bluff country, though the modest 180 feet of elevation gain is distributed gradually rather than concentrated in severe climbs.
The single-track segments test handling skills on narrow, twisting trails, while the prairie portions provide visual relief and chances to recover between technical sections. The route's design emphasizes the park's natural variety, moving runners through different ecosystems that each present their own tactical challenges.
