The race

What this one is

El Diablo Hundo is a trail ultra at Lake Bistineau State Park in Doyline, Louisiana, run every October over a repeating 10-mile loop combining the Blue Wing, Koasati, and Whoa Mule trails. Runners choose a 25K, 50 Mile, 100K, or 100 Mile distance, all on the same loop with the same start/finish aid station. The course is flat, with mud and tree roots rather than climbing, and the cutoffs are set to be finishable: 40 hours for the 100 Mile and 100K, 15 hours for the 25K and 50 Mile.

El Diablo Hundo held its first edition in October 2025, with the 100 Mile, 100K, and 25K distances. A 50 Mile option was added for the 2026 edition.
