Two Hollows Monster Marathon

Two Hollows Monster Marathon and Half Marathon

The Two Hollows Monster features a marathon and a half marathon on well-maintained trails in the western section of Kennedy State Forest between Virgil and Harford, New York. The course follows rolling single track with twists, turns, and several hills, including a notable climb in the last two miles of each 13.1 mile loop. Runners pass through shady hemlock groves, fern-carpeted hardwood forest, and a few longer viewpoints. The route is run as a double out and back; marathoners complete the loop twice.

Start times are staggered by age and gender based on age-grading; a nonbinary category is included. The event uses a compact course footprint, staggered starts, generous cutoffs for the marathon, and aid stations spaced about 3 to 4 miles apart. This is a cupless race so all participants must carry a personal hydration system. Port a potties are provided near the start and finish.

Logistics note: the venue is near the intersection of Adams Road and Owego Hill Road with parking on Adams Road and all wheels off the pavement. Policies include no dogs, no headphones, and no jogging strollers. Awards include a participation award for all finishers and awards to the top five finishers in each distance, with placing adjusted for the age and gender based starts.

The event is part of the Finger Lakes Trail Circuit and takes place on trails maintained in coordination with local trail stewards. Trail conditions, ticks, uneven footing, and variable weather are noted hazards. Visit the organization's website for the most recent information.
