Race Information

Eastern States

Eastern States is a 103-mile single-loop trail race (98% single/double-track) in the Wilds region of the Allegheny Plateau in north-central Pennsylvania.  The race circumnavigates a portion of the stunning Pine Creek watershed that includes some of our longest climbs and most technical and remote terrain.  It visits storied trails like the Mid State Trail and the Black Forest Trail, and accumulates over 20,000 feet of climbing in the process — all in the glorious heat and humidity of August.  This is graduate-level trail running that will both test and fulfill you in so many ways.

Qualification Standard

This is NOT an entry-level race.  Because of the difficult and remote terrain, the potential heat and humidity, and the large amount of climbing, you must qualify to enter Eastern States.
To qualify, you must either complete a 50-mile trail race within 16 hours, or complete a trail race longer than 50 miles within that race’s official cut-off time. You must complete this qualifying race in either 2021, 2022 or 2023, and you must have already completed it to register. We will review your qualifying race when you register, so please be sure it’s an official race with results published on a publicly available website.

Associated Races

The Ironstone 100K is a point-to-point “Ridge and Valley Appalachian” 100 kilometer ultramarathon in Southwest Central Pennsylvania. Amazing in its terrain and rich in heritage, the ultramarathon starts at Canoe Creek State Park in Blair County and utilizes the Standing Stone, Mid State, and Lower Trails before ending in Greenwood Furnace State Park in Huntingdon County.
With its unforgiving technical terrain, it will be one of the most challenging ultras in the region, on par with races like Eastern States 100, Black Forest 100K and Worlds End Ultramarathon. The most unique feature of the Ironstone 100K is the ridge running atop Tussey Mountain, one of the longest named ridges in the Appalachians – a folded and fractured ridgeline of sandstone and quartzite. Other features include old-growth pines at Alan Seeger Natural Area, Little Juniata Natural Area, the Lower Trail rails-to-trail along the Frankstown Branch of the Juniata River and the historic limestone kilns at Canoe Creek State Park.
