Run the legendary Leadville 10K and feel the magic of the Race Across the Sky
Overview
The Leadville Trail Marathon and Heavy Half is not your average mountain race. Known as the nation’s toughest marathon, this legendary event takes runners high into the Rocky Mountains, climbing rugged mining roads and alpine trails that lead to the top of Mosquito Pass at 13,185 feet. The thin air and steep climbs test your grit, while the sweeping mountain views reward every ounce of effort.
This is the race where endurance athletes from across the globe come to prove themselves. The atmosphere in Leadville is electric, with crews, volunteers, and locals cheering on every step of the journey. Whether you are pushing for a personal best or simply chasing the finish line at altitude, this race will challenge and inspire you in ways few others can.
