The course covers diverse terrain including jeep trails, single-track paths, historic estate roads, and highly technical sections requiring scrambling. The signature feature is the ascent of Breakneck Ridge itself, a steep, exposed climb over rock faces that demands both physical fitness and comfort with exposure. Technical stretches require careful foot placement and tolerance for challenging terrain conditions.
Runners experience significant elevation changes throughout, with the full marathon featuring approximately 9,000 feet of gain and loss over 26.4 miles. The half marathon covers 14.5 miles with 4,800 feet of elevation change. Both courses offer sweeping views of the Hudson River valley and surrounding mountains, particularly from the exposed sections of Breakneck Ridge.
