Set in the scenic Ozark hills of Waynesville, Missouri, the Bad Dawg Ultra Endurance Run returns on August 15, 2026, offering a challenging yet rewarding experience for ultrarunners and those looking to push their limits. Choose your adventure from distances including 100 Miles, 100K, 50 Miles, 50K, or a 12-mile run/ruck. The "no-frills" event, organized by ultrarunners for ultrarunners, takes place on a 10-mile out-and-back loop featuring packed gravel roads with rolling hills and picturesque tree-lined country views. While often described as having "a few rolling hills and lots of flat gravel," runners should be prepared for typical Ozark terrain, with some finding it "a little hillier than I expected".

Typical race day conditions in mid-August can see highs around 87°F and lows around 66°F, with a 14% chance of precipitation, contributing to the race's reputation for being hot and humid. To support runners through the challenge, aid stations are strategically placed at the start/finish and the 5-mile turnaround point, offering water, Gatorade, typical aid station fare, and the unique addition of hot quesadillas at the main station. For those tackling the longer distances, a 36-hour cutoff is in place, with an optional early start on Friday evening for 100-mile and 100K participants seeking additional time (though not eligible for overall awards).

Beyond the personal challenge, the Bad Dawg Ultra is renowned for its heartwarming mission: supporting the "OneSolePurpose" project to provide new shoes to elementary students in Title 1 school districts. The race fosters a welcoming atmosphere, even allowing well-behaved pets, and offers a free pasta dinner the night before the race. Finishers of the ultras receive a custom belt buckle and bumper sticker, with 100-mile finishers also earning a custom gym bag, while 12-mile participants collect a unique medal or patch. Camping is available in the parking lot at the start/finish area, enhancing the camaraderie of this purpose-driven endurance event.
