Worlds End Ultra 50k
We have a reputation as one of the toughest, most scenic trail 50k’s on the east coast.
The course is predominantly rugged single-track that winds it's 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 Butternut View, High Rock Vista, and Canyon Vista - along with spectacular cascades and falls like Alpine Falls and Double Run. You'll pass many interesting rock formations, take in the tranquility of Sones Pond and 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 it's 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 5,900 feet. Combine this with the often rock strewn, technical trail along with the number of times you'll stop to take in the scenery, and you'll quickly realize this isn't a course you'll try to set any personal records on. 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 - enough eye candy to keep you busy for your entire run. But don't linger too long at any one place, you only have 12 hours to complete this race.
Make no mistake, this race is intended to grind you down over the long haul. Luckily, we'll take care of you with 6 aid stations along the way. Not only will you see the usual ultra spread, expect to see a plethora of other delicious treats to keep you moving to the finish line. You'll also have 2 aid stations that will be crew accessible.
We will not be requiring a qualification standard for the 50k race. Be aware though, this race is NOT a beginners-level 50k race since you will need to negotiate rock fields, narrow and uneven terrain, steep climbs, precipitous descents, and even a cliff side trail over flowing water. If you feel up to the task, confident in your ability, and prepare yourself accordingly - please feel free to sign up!
