The race is held at the beautiful Dinosaur Valley State Park in Glen Rose, Texas. 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 NO river crossings. 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.
