Start slots open from 6:45 a.m. with limited capacity in each wave, and aid stations along the course carry cut-off times. Fair Hill’s rolling farmland and woodland trails are a well known training ground in the region, which makes this a convenient long-distance target for hikers across the tri-state area.
