Hill to Hollow 100km
SCTR is excited to announce the first-ever running of the Hill to Hollow 100km, co-directed with Pete Dady of the Hash House Harriers who traversed the loop back in the COVID days. Crossing four counties, the course will begin and end in Morgan Hill State Forest (camping available), following the nearly-all-single-track Onondaga Trail alongside misty ponds, up to incredible vistas, and crossing above waterfalls; past the highest point in Onondaga County on single track mountain bike trails within Morgan Hill State Forest. The course then follows the Onondaga Trail/North Country Trail east to Highland Forest County Park and past DeRuyter Reservoir, turning south on the enigmatic Link Trail through Muller Hill State Forest before joining the main Finger Lakes Trail in Mariposa State Forest, heading west past Chippewa Falls, and rejoining the Onondaga Trail to reenter Morgan Hill State Forest.
This is a VERY challenging 100km and will be more dirt bag ultra than ultra-luxe for this first year, with a commensurate 50% discount reflected in the registration price. Self-sufficiency and strong navigation skills (without 5G/LTE network coverage) are musts, but how many people can say they were part of the birth of an ultra?
Hill to Hollow 100km take place concurrently with the Morgan Hill Trail Races Half Marathon & Marathon, is Trail Sisters approved, and is a UTMB Index race.
