Hawk

Founded in 2011 by the Lawrence Trail Hawks, the Hawk Hundred runs four 25-mile loops of technical, color-blazed single-track at Clinton State Park outside Lawrence, Kansas — Sanders Mound, Cactus Ridge, and two ascents of Bunker Hill per lap. The terrain rolls persistently despite the prairie setting. Three aid stations serve runners at roughly miles 4.5, 10.5–13, and 25 per loop; crew access at two. Final cutoff is Sunday 2 PM. Sub-24-hour 100-mile finishers earn a distinct buckle design; all finishers receive a buckle.
