Course
Loop courses run entirely on the trails of Cougar Mountain, starting and finishing at the Sky Country Trailhead outside Issaquah, Washington. Longer loops are supported by several aid stations, including one at DeLeo Wall. The series runs monthly through the summer, each month offering a different pair of loop distances.
