Dinosaur Valley Endurance Run

The Dinosaur Valley Endurance Run (fka Big Cedar Endurance Run) was the first 100 mile trail running event in North Texas!
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.
The course is a one-way traffic 16.67-mile loop.

– 100 Mile: 6 x 16.67-mile loops.

– 50 Mile: 3 x 16.67-mile loops.

– 50K: 2 x 16.67-mile loops; starts Sat.

– Half Marathon: 1 x a shortened 13.1-mile loop; starts Sat.
This race has a limit of 300 total participants. Emphasis will be on the longer distances so shorter distances may close temporarily if they fill too fast to allow certain percentages in each distance. Some swag as we get closer to race day will be limited to the first X that sign up in that distance once orders are placed.
We understand that LIFE HAPPENS! Note that, unlike a lot of races, this race offers a refund policy (described below) and even refunds if you downgrade your distance (also described below). You may also go up in distance up until the start of the race (also described below). So there is no downside for committing to your goal now!
