The Dinosaur Valley Endurance Run takes place at Dinosaur Valley State Park in Glen Rose, Texas. The event offers five distances—100 Miler, 100K, 50K, 25K, and a 5 Miler—designed to challenge runners of all levels. Runners traverse a hilly course with a mix of soft dirt, rocks and roots; some sections are technical while others are highly runnable.
