This is STL’s Original 100-mile trail ultra! Be part of the adventure as we run through the beautiful Beaumont Scout Reservation, with trails that are typically closed to the public.

Important Details:

• Each runner navigates a course with 5 legs, creating various loops for different distances: 1x for 20mi, 2x for 40mi, 3x for 100K, and 5x for 100mi.
• Course changes direction annually - clockwise on odd years and counterclockwise on even years.
• Two indoor aid stations are available multiple times throughout the loop.
