*Hill climb gradients are measures of slope steepness. A 1% gradient rises 1 unit vertically for every 100 units horizontally. Steeper gradients, like 10%, indicate a steeper slope. At 20%, slopes become very steep, and 30% or higher gradients are extremely challenging, approaching near-vertical terrain. Gradient is essential in road design, biking, and hiking planning.*
