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
Run through the historic mining district’s challenging old mining roads and trails, and hit a high of 13,185 feet at Mosquito Pass during the Life Time Leadville Trail Marathon and Heavy Half presented by La Sportiva.
Take on 50 miles of extreme territory that starts at 10,200 feet and reaches 12,000 feet on four separate occasions at the Life Time Silver Rush 50 Run presented by La Sportiva. It will leave your lungs burning, heart pounding and eyes completely amazed — while also preparing you for the pinnacle Leadville Trail 100 Run presented by La Sportiva.
Take on 50 miles that will put your skills and endurance to the test. Technical climbs and descents are met with the glorious mountain views of Leadville. 8,000 feet of elevation gain over these 50 miles presents an excellent test for the Stages Cycling Leadville Trail 100 MTB in August. Test your limits with the Silver Rush 50 MTB.
This is it, the race of all races. One hundred miles across the high-altitude, extreme terrain of the Colorado Rockies, this event was created for only the most determined athletes. Starting at 10,152 feet and climbing to 12,424 feet, you’ll be challenged to catch your breath — while the views try to take it away.
The legendary “Race Across The Sky” 100-mile run is where it all started back in 1983. This is it. The race where legends are created and limits are tested. One hundred miles of extreme Colorado Rockies terrain — from elevations of 9,200 to 12,600 feet. You will give the mountain respect, and earn respect from all.
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!
