Hill to Hollow 100km

The Hill to Hollow 100km is scheduled for September 18, 2027 in Fabius, NY and is organized by Salt City Trail Racing. The event offers the following distances:

  • 100 km Solo
  • 100 km Relay

The course crosses four counties and begins and ends in Morgan Hill State Forest, where camping is available. It follows nearly all single-track Onondaga Trail along ponds, vistas, and waterfalls, then continues on the Onondaga Trail/North Country Trail east to Highland Forest County Park and past DeRuyter Reservoir. The route turns south on the Link Trail through Muller Hill State Forest, joins the Finger Lakes Trail in Mariposa State Forest, passes Chippewa Falls, and returns to Morgan Hill State Forest.

Course metrics and logistics include an approximate distance of ~62.5 miles, about 10,348 feet of elevation change, seven aid stations (excluding start/finish), and a 20 hour hard cutoff. Solo runners may use one pacer after roughly mile 31.9 at Aid Station 4, and pacer or relay exchanges are allowed only at aid stations. For 2026, crew were permitted to assist runners anywhere on course provided they did not park on private property.

This is a race that requires self sufficiency and navigation skills without reliable 5G or LTE coverage. Required gear includes a fully charged cell phone kept on with the race director number saved, an offline navigation device with the course GPS file loaded, headlamp and extra batteries, reflective vest, emergency blanket, waterproof shell with hood, a water filtration device, at least 800 mL of liquid capacity, and at least 400 kcal of food reserve.

Aid station offerings include ice if needed, water, Skratch, fruit, pickles, sandwiches, chips, cookies, candy, and a limited selection of hot foods at Aid Station 6. Road access to aid stations may be restricted for low clearance vehicles. All entrants receive SCTR socks and finishers receive a limited edition hand glazed mug. Prizes are awarded to top finishers in each gender division and to the fastest relay team. The event runs concurrently with the Morgan Hill Trail Races Half Marathon and Marathon, is Trail Sisters approved, and is a UTMB Index race. Online registration closes September 17 at 11:59 PM ET.
