Hill to Hollow 100km : Tully, NY

Hill to Hollow is a trail event organized by Salt City Trail Racing offering two distances: a 100km Solo and a 100km Relay.

The course begins and ends in Morgan Hill State Forest (camping available) and crosses four counties. It follows mostly single-track trail sections on the Onondaga Trail and North Country Trail, passing ponds, waterfalls, high vistas, the highest point in Onondaga County, Highland Forest County Park, DeRuyter Reservoir, Muller Hill State Forest, Mariposa State Forest, and Chippewa Falls before returning to Morgan Hill.

Key metrics include roughly 63.7 miles and about 10,286 feet of elevation change, with a 20 hour hard cutoff. There are seven aid stations on course (excluding start/finish). Aid stations offer water, Skratch, ice if warranted, fruit, pickles, PB&J, chips, pretzels, cookies, candy, and a limited selection of hot foods at Aid Station 7.

Pacers are permitted for 100km solo runners after approximately mile 33; only one pacer per runner at a time and pacer or relay changes are allowed only at aid stations. Crew access is available to aid stations, though some roads may not be suitable for low-clearance vehicles.

Required gear includes an offline-capable navigation device with the course GPS loaded, a fully charged cell phone kept on with race director number saved, headlamp and extra batteries, reflective vest, emergency blanket, waterproof shell with hood, a water filtration device, at least 800 mL liquid capacity, and a minimum 400 kcal food reserve.

The event runs concurrently with the Morgan Hill Trail Races Half Marathon and Marathon, is Trail Sisters approved, and is a UTMB Index race. Visit the organization's website for the most recent information.
