The Mammoth at Dinosaur Valley


IT'S A WHOLE DIFFERENT ANIMAL! 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, TX.  With FOUR different distances to offer, all 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 parks 20 miles of single-track dirt and limestone trails. Mild to significant elevation gains, low level water crossings, NATURAL OBSTACLES and amazing scenary will make THE MAMMOTH an ADVENTURE RUN run not to be missed!
