UNBOUND Gravel~June 1st 2024

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

Dead Horse Ultra ~ November 16th 2024

There's a reason this is one of the biggest trail running events in the country! Moab in November is a trail runner's dream...perfect weather and world class single track make this event one you don't want to miss. Featuring the Magnificent Seven trail system, the course will challenge you with technical slickrock and rocky climbs. Runners make their way up the Gemini Bridges Trail to the first aid station with views from Court Point and into the beautiful Bride Canyon. After the 15 mile aid station, runners are treated to the extraordinary views from Bull Run Trail. Every crest and turn gives stunning views of Arches National Park, the La Sal Mountains, and the Moab Valley. Come see why this race sells out year after year!
