Dinosaur Valley Endurance Run
Glen Rose, United States • 22-23 Nov 2025
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. Now in its eighth year, the race emphasizes inclusion and community, with a waitlist, a Trail Mix Fund partnership for fee assistance, and Western States qualifying status for the 100K and 100 Miler. It remains a scenic, competitive test of endurance in North Texas. Visit the organization's website for the most recent information.
