The Great Hill Ultra traverses 62 miles through hills and valleys of the beautiful Finger Lakes. Full of challenging terrain, gully rim trails and exceptional views, this course meanders through swamplands and hilltops with a romp through charming downtown Naples. We’ve linked together our favorite Naples area trails ending in the West River Valley in the shadow of the Great Hill. This community-supported event is filled with great folks and great trails. These are our favorite areas packaged up for you in one spectacularly challenging run. And now a 50k course! Starting at the Great Hill Ultra mid-point at the base of Cleveland Hill, runners descend via the Finger Lakes Trail into downtown Naples and complete the Hi-Tor Wildlife Management Area sections above downtown Naples and the circumnavigation of Great Hill ending in the shadow of Great Hill.
