The marathon course covers the Rail Trail from end-to-end with loops around Lake Owen. It averages 8,926 feet in elevation. The trail is a gently graded, wide, gravel path. Marathon participants follow the course through two states (the trail briefly dips into Colorado after starting just north of the state line) and finish at a serene mountain lake. The half-marathon course mirrors much of the northern portion of the marathon course, including two loops around Lake Owen. Source
