The Mammoth Race

The Mammoth is a family-friendly, single day, multi-distance trail run. For the third year, we are proud to be back to Dinosaur Valley State Park in Glen Rose. With four different distances to offer, all ages and athletic abilities will be able to run their race. Race individually or with a non-competitive team. The courses will utilize a part of the park's 20 miles of single-track dirt and limestone trails. Mild to significant elevation gains, low-level water crossings, natural obstacles, and amazing scenery will make The Mammoth an adventure run not to be missed!
