Welcome to the West Virginia Trail Festival (WvTF). WILD. TOUGH. FUN. This family-oriented annual trail running event will occur every May in the heart of Pocahontas County, WV!

It’s the spirit that 4,000 riders bring with them to the Flint Hills of Kansas for one weekend each spring; the spirit of an event that began with 34 participants in 2006 and now stands as the “World’s Premier Gravel Event.” And so it is fitting that the event and its organization, the one embodied by a limitless ethos that calls Emporia home, now has a name to match its ferocious spirit.” -Emporia Gazette

The OSS/CIA 50 Mile Night Run traverses the historic trail of today's Prince William Forest Park.  In the days leading up to and during World War II, the Park, its trails, and Cabin Camps were the secretive training sites of the Office of Strategic Service, the organization predecessor to the CIA.  Runners have up to 14.5 hours to complete their mission with a tighter 13 hour cut-off for podium driven runners!  The course features two large 25.5 mile loops covering all corners of the Park.  Starting just before sunset and finishing at 8:30am, runners will not run the same sections of the course in daylight and the night will remain a mystery.  Come and see what our little secret is all about

Forget what you know about 50-milers. Manitou’s Revenge is a different beast — feral, unforgiving, and wholly indifferent to your pain. 53 miles and 15,000 vertical feet of jagged Catskill wilderness, you’ll claw through technical climbs, stagger down rock-strewn descents, and scramble on all fours more times than you’ll want to admit.

Yes, there are moments you can run. But they’re fleeting. This course is designed to slow you down — and break you open. That’s why we give you 23 hours. That’s why there are only 9 aid stations. This is self-sufficiency on a stopwatch. Between checkpoints, you’ll go hours alone — with only the terrain, your breath, and your doubts for company.

TrailCon is a trail running festival designed to inform, educate and inspire, through panels, activations and gatherings.

The Western States ® 100-Mile Endurance Run is the world’s oldest 100 mile trail race.

In the decades since its inception in 1974, Western States has come to represent one of the ultimate endurance tests in the world.

This is it. The Race of All Races. Where it all began.

In 1983, 45 tough-minded runners braved 100 miles of high-altitude, extreme Rocky Mountain terrain — starting at 10,200 feet, climbing to 12,500 feet and running into global endurance history. Today, the Life Time Leadville Trail 100 RUN presented by La Sportiva is one of the oldest, most storied endurance running events in the world — with not one, but two climbs on the crux of the course: Hope Pass (12,500 feet). Every year, a select handful of gritty, gutsy and determined runners make the pilgrimage to Cloud City to Race Across the Sky and take their shot at etching their name among the Leadville Legendary. The red carpet awaits.
