The Dinosaur Valley Endurance Run (fka Big Cedar Endurance Run) was the first 100 mile trail running event in North Texas! 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 continues to grow every year, now offering 5 distances so there’s a challenge for every interest level. Across these distances, you’ll be among other amazing athletes challenging themselves. There are lots of gradual up and downhills that add up, and a mix of terrain between soft dirt, rocks, and roots. Some parts are technical while other parts are super runnable. This is a pretty hilly 100 miler by Texas standards, and the terrain can trip you up as you fatigue. Use that first loop through the course to settle into a pace for the race and not go out too fast.
The 100K is now a Western States qualifying race!!! This event has grown tremendously and shown a level of execution that puts us on a national level. We are now one of only 18 100K qualifiers in the United States for the Western States Endurance Run race.
If you complete the 100K distance in under 22 hours, you earn your qualifier for the next year’s lottery.
The 50K, 25K, and 5 Mile entrants have the ultimate in flexibility – now runners can choose for themselves whether they run the race on Saturday or Sunday. All 3 distances will start at 8 am Saturday and 8 am Sunday. You can decide up until the last minute, and you don’t have to say ahead of time which day you will run. Our timing system will start recording you when you start either day!
Please only pick up your packet on the day you are running so that you don’t accidentally have your timing chip read by the timing system near the start line. Results will be combined after both days of races, and awards mailed out.
For 50Kers doing Sunday, please keep an eye on cutoffs which you must still meet.
For those in the 100 mile and 100K, this means the race course will never get too lonely. It will help keep the energy up through the whole weekend!

Killer race team, but a killer course!
The course is beautiful but extremely difficult with mostly technical single track. It's mostly rocky - so many rocks. Poles are very helpful. The aid stations are so well stocked … MORE
The course is beautiful but extremely difficult with mostly technical single track. It’s mostly rocky – so many rocks. Poles are very helpful. The aid stations are so well stocked and supportive! The runner village is organized nicely, and the finisher buckle is very cool. This race chewed me up hard!

~10.5 mile loop trail through Dinosaur Valley State Park. I needed shoes with a rock plate 🙂 There were a few hill that caught up with me toward the end. It was a nice race experience.
Great aid stations and volunteers. I was with a group that had folks running 50k, 100k and 100 miles!
Race Swag: Cool Hoodie plus a wooden medal. Plus if you registered early you could pick your bib number and add a name to it.
