Dinosaur Valley Endurance Run
The race is held at the beautiful Dinosaur Valley State Park in Glen Rose, Texas. This course has rolling and sustained ascents and descents that take you through varied terrain. There are amazing overlooks on this course where you can see for miles. The event offers race distances of 5 miles, 25K, 50K, 100K, and 100 miles. 100 milers get a recorded time for 100K distance, and the race is a 100K qualifier for the Western States Endurance Run for all those who pass the 100K distance in under 22 hours. The race is also a 100 mile qualifier for the Western States Endurance Run for all those who complete 100 miles in under 35 hours.
Helping Our Community
One of many examples: One year we donated $4,000 to Dinosaur Valley State Park to buy a rescue skid (like a sturdy medical gurney) to attach to their new EMS ATV to get people with medical emergencies off the trail quickly!
We are a Western States qualifier.
And those entered in the 100K and the 100 miler can earn their qualifier with our unique setup.
Changes from 2025 to 2026
We are always looking to improve the event. We listen to your feedback in our post-race surveys, and we evolve your experience! See the changes here.
Reasons to Race with Us! There are lots of reasons, but we'll give you ten!
Land Acknowledgment
We support the Running on Native Lands Initiative, a program by Rising Hearts. This race takes place on land regions that were the traditional territory of the Jumanos, Wichita, Nʉmʉnʉʉ Sookobitʉ (Comanche), and Kiikaapoi (Kickapoo) peoples throughout the land’s history. We recognize these lands were stolen from these Indigenous tribes. They protected and cared for these lands, and we need to continue to do that too.
Volunteers Needed!
They make events happen!
