This week on The Running Mullet: We’re heading deep into the mountains of Pennsylvania for one of the toughest, muddiest races on the East Coast: Worlds End Ultramarathon. From the tough climbs of the Loyalsock Trail to the rock gardens, waterfalls, creek crossings, and endless rollers, Worlds End isn’t just a race — it’s a survival experience. The 50k offers up nearly 6,000 feet of climbing, while the legendary 100k throws down over 12,000 feet with a strict 19-hour cutoff. This race has built a reputation as one of the hardest and most scenic ultras in Pennsylvania — and one runners obsess over all year because registration disappears in minutes. On this episode: What makes Worlds End so memorable Why this course humbles even experienced ultrarunners Race strategy, cutoffs, and surviving the relentless terrain The atmosphere, community, and why people keep coming back year after year Whether you’re toeing the line this weekend, crewing someone through the night, or just dreaming about someday tackling Worlds End yourself… join us.
