Two Hollows Monster Marathon

Harford, United States • 30 Aug 2026

Two Hollows Monster Marathon and Half Marathon - Kennedy State Forest

The Finger Lakes Runners Club stages a trail marathon and half marathon on well-maintained paths in the western section of Kennedy State Forest, between Virgil and Harford, New York. Distances offered:

  • Marathon: 26.2 miles
  • Half marathon: 13.1 miles

The course runs between Daisy Hollow and Babcock Hollow and uses a double out-and-back layout. Terrain includes long, rolling single track, twists, several steep hills including one in the final two miles of each 13.1-mile loop, shady hemlock groves, fern-carpeted hardwood, and occasional long views. Elevation gain is about 4,400 feet for the marathon and about 2,200 feet for the half.

Start times are staggered by age and gender using a "monster" head-start system that includes a nonbinary category; finishing order is adjusted by these head starts. Aid stations are located roughly every 3 to 4 miles and port-a-potties are available near the start area. The event is cupless, so all participants must carry a personal hydration system.

Policies include parking on Adams Road with all tires off the pavement, no dogs, no headphones, and no jogging strollers. There are midpoint and later cutoffs for the marathon; runners who miss those cutoffs will not be allowed to continue. Awards include a participation item for all and awards for the top five finishers in each distance, with placement accounting for the age and gender head starts.
