El Diablo Hundo

El Diablo Hundo is an ultramarathon event held at Lake Bistineau State Park in Doyline, Louisiana. The race features three distances: a 100-mile, a 100K, and a 25K, all run on a 10-mile loop course combining the Blue Wing, Koasati, and Whoa Mule trails. The terrain is typical Louisiana State Park trail style—flat with minimal elevation, muddy sections, tree roots, and natural surfaces.

Two aid stations support runners, including a main station with hot food and snacks. The scenic park offers beautiful hardwood forests, cypress and tupelo stands, and recreational amenities, making for a challenging yet picturesque race experience.
