High Point

Threemile Ridge is a favorite of local riders for its sweat and speed. The labor, mitigated by super-vistas during the first 10 miles on the Continental Divide Trail, gives way to velocity when the bottom drops out for 3,000 vertical feet on a twisted two-track that flows like a tumbling stream. For this classic descent, pack a spare set of brake pads. After the ride, if your brakes still work, stop at the Broken Arrow for frosty drinks and fantastic Mexican food.
