The 'Not Assigned' trail offers a moderate challenge with a vertical relief of 325 feet. The median slope (p50) is 2, and the 90th percentile slope (p90) is 4. This means that while much of the trail is relatively gentle, there are sections with steeper inclines that could be more tiring for dogs, especially smaller breeds or those less accustomed to varied terrain. The network route type suggests a variety of path conditions, allowing for some flexibility in choosing your route based on your dog's energy levels.

Surface
