Bad Dawg Ultra Endurance Run

The Bad Dawg Ultra Endurance Run takes place August 15–16, 2026 in Waynesville, MO. This is the sixth annual running of the event, organized by Frog Fitness Group. The race uses a simple format on a 10 mile out and back loop through the Ozarks with packed gravel, rolling hills, and tree cover.

Two aid stations support the course: a fully stocked station at the start and finish, and a minimally stocked turnaround. Both stations provide Gatorade, water, typical aid station food, and bathrooms. All turnarounds are clearly marked.
