Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The race

What this one is

Eastern States 100 is a 103.5 mile loop around the Pine Creek watershed in the Pennsylvania Wilds, starting and finishing at Little Pine State Park in Waterville. It strings together the Mid State Trail, the Black Forest Trail and the West Rim Trail, with 21,000 feet of climbing, rock underfoot and August heat and humidity. Runners get 36 hours. Since 2014 about half the field has finished, and in hot years it drops into the thirties.

The first Eastern States 100 was run in 2014. It has been held ten times through 2026; the 2018, 2020 and 2024 editions were cancelled. The aid stations have moved over the years. Halfway House at the PA-44 crossing gave way to Big Trail in 2021, and Algerine and Long Branch were both replaced by Cedar Run in 2023. In 2026 a woman won the race outright for the first time, and it was the first sub-24 hour women's finish in the race's history.
