Two Hollows Monster Marathon

Dryden, United States • 24 Aug 2025

The Two Hollows Monster Marathon and Half Marathon takes place in the scenic Kennedy State Forest near Virgil, NY, featuring well-maintained trails between Daisy Hollow and Babcock Hollow. The course offers rolling single-track paths, challenging hills, and shaded hemlock and hardwood forests, with the marathon including about 4,400 feet of elevation gain and the half marathon 2,200 feet. Unique to this event are age- and gender-based staggered start times, including a nonbinary category, allowing older and non-male runners to start earlier. Aid stations are spaced every 3–4 miles, but the race is cupless, requiring runners to carry personal hydration. It’s ideal for both first-time trail marathoners and ultra runners preparing for longer races. Visit the organization's website for the most recent information.
