Race Info

The Two Hollows Monster Marathon and Half Marathon runs on single-track trails in the Kennedy State Forest between Virgil and Harford, New York. The marathon repeats the half marathon's 13.1-mile loop twice, with roughly 4,400 feet of elevation gain over the full distance versus 2,200 feet for the half. The race uses staggered age- and gender-based starts, giving older and non-male runners an earlier gun time. On the current course, Ryan Allen-Parrot holds the marathon record at 4:25:23 (2024) and Nancy Kleinrock holds the half marathon record at 1:39:35 (2023).
