Worlds End Ultramarathon

Worlds End Ultramarathon

The Worlds End Ultramarathon is a challenging foot race that explores the Loyalsock Trail, Loyalsock State Forest and Worlds End State Park in the Endless Mountains of Pennsylvania. The routes are largely rugged, scenic-dense single-track trails with some fairly remote sections, several waterfalls and multiple vistas of the beautiful Endless Mountains. This is NOT a beginner-level ultra and participation in the race should not be taken lightly.

100k Course Description

The 100k course is predominantly rugged single-track. The race was designed around the famed Loyalsock Trail but to complete the loop back to Worlds End State Park, you'll spend plenty of time exploring side trails of equal beauty. The course runs deep in the Pennsylvania hills with rocky hollows, diverse forests, narrow gorges and endless views. You only have 19 hours to complete this race. There will be 13 aid stations along the way, 4 of which are crew accessible, and 3 locations to pick up and swap pacers from.

The Worlds End 100k is also part of the Pennsylvania Triple Crown of Mountain Running series.

50k Course Description

The 50k course follows the same route as the 100k but veers off to bring you home before the start of the lower loop. While only half the distance and half the elevation (5,800 feet), it's still chock full of fabulous scenery and awesome trails. You have a 12-hour time limit to complete the course. There will be 6 aid stations along the way. No aid station is crew accessible and no pacers are permitted in the 50k race.
