One of the toughest and most beautiful courses you’ll find anywhere! 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. The PA Department of Conservation and Natural Resources describes Worlds End State Park as "virtually in a class by itself, this wild, rugged and rustic area seems almost untamed." This is NOT a beginner-level ultra and participation in the race should not be taken lightly.
The course is predominantly rugged single-track that winds its way through the Endless Mountains in the Loyalsock State Forest and Worlds End State Park. Your effort will reward you with beautiful overlooks such as:
Along with spectacular cascades and falls like Double Run, Dry Run, Rode Falls and Lee's Falls in the Ketchum Run Gorge, you'll pass many interesting rock formations such as Split Rock, take in the tranquility of Sones Pond, and climb a wooden ladder alongside Rode Falls. You may even see a bald eagle soar beside you as you traverse the rocky ledge of trail that overhangs the Loyalsock Creek.
This course can be described as "hilly" or "rolling" with its steepest sustained climb only being about 1,000 rocky feet. The deceptive part is that there is a never ending supply of shorter climbs that the trail throws at you to give an unexpected overall elevation gain of about:
Make no mistake, this race is intended to grind you down over the long haul. Luckily, we'll take care of you with:
The Worlds End 100k is also part of the Pennsylvania Triple Crown of Mountain Running series. These races showcase the best of Pennsylvania’s ultra mountain-running scene and celebrates the wild beauty of these rugged old mountains, and the vibrant trail-running culture that thrives in them. Do you have what it takes to tame the wilderness races of PA?
If you are not ready to tackle the full 100k but still want to take in the beauty of Worlds End, you can still challenge yourself with the 50k course. The race 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. We also give you a more generous:
