A percentage of all entry fees will support ITA! Participants will run or hike a challenging 10K (6.2 miles) or 2.9-mile course that takes them around the Crater Rings, a unique site featuring one of the very few examples of volcanic pit craters in the continental United States, recognized as a National Natural Landmark.
