DINO returns (for the first time since 2013), to DePauw Nature Park, which offers stunning views in, and above, its rock quarry cliffs. The trail surface is mostly crushed stone, making it great for running when springtime trails are wet. It's an excellent choice for first time trail runners. There are a couple of steep hills of 50 to 100' vertical climb, but the majority of the route has very mild grades.
