Race Information
The Dinosaur Valley Endurance Run takes place at beautiful Dinosaur Valley State Park in Glen Rose. 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, including amazing overlooks where you can see for miles.
