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 fifth year! Are you ready to tackle Dino Valley?

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!

This course has rolling and sustained ascents and descents, although none are terribly steep. The loops take you through varied terrain, from double track trails in fields to single track in wooded areas. There is a mix of packed dirt, smaller rocks, larger rocks, slick rock, and some roots. There are also two river crossings per race loop. This course really has a little of everything, which includes its views. There are amazing overlooks on this course where you can see for miles.

(Details on how the venue change came about are here... The first two years the race took place at the highest point in the city of Dallas, Prayer Mountain, which is home to the Mountain Creek Church. The church owns the Big Cedar Wilderness Trail, which is maintained by the Dallas Off-Road Bike Association.)
