Big Cedar Endurance Run (now renamed the Dinosaur Valley Endurance Run) was the first 100 mile trailrunning event in North Texas! Now join us for our fourth year!

In 2016, due to land ownership issues with our usual venue, the Big Cedar Wilderness Trail in Dallas, we moved the race to the beautiful Dinosaur Valley State Park in Glen Rose, Texas. And it was such a fantastic race course and so well-received, and the state park was so hospitable to our runners, that we have moved to Dinosaur Valley State Park permanently and renamed the race the Dinosaur Valley Endurance Run!
